Abstract:
A system for retrieving and disseminating information records from Internet sources includes a client device and an intermediary server system, including software, between the client device and the Internet. The system collects a record specific to a client from an individual one of said Internet sources in a first form in which the record is recorded at the Internet source, transforms the record from the first form to a second form specific to an application other than an Internet browser application, the application executable by the client device, and transmits the transformed record to the client device for display in the application other than an Internet browser application executable by the client device. In some cases the client device connects by a data link that is not Internet-compatible link. Data mining on the Internet specific to clients and client devices is taught, with aggregation services and synchronization for keeping a client up-to-date efficiently for changing data content.

CROSS-REFERENCE TO RELATED DOCUMENTS 
   The present application is related in part to U.S. patent application Ser. No. 09/323,598 filed on Jun. 1, 1999 now U.S. Pat. No. 6,477,565 and entitled “Method and Apparatus for Obtaining and Presenting WEB Summaries to Users”, the content of which is incorporated in its entirety by reference. 

   FIELD OF THE INVENTION 
   The present invention is in the field of network information services including data gathering and transmission over wired and wireless network connections and pertains more particularly to restructuring of personal data and, in some cases, general data for the purpose of enabling receipt of such data by a variety of connected and portable network appliances without requiring added hardware or software. 
   BACKGROUND OF THE INVENTION 
   The information system known in the art as the Internet, and the Internet subset known as the World Wide Web (WWW), represents the largest publicly available source of information in the world. Anyone with an Internet-capable appliance and an Internet connection can navigate the Internet for the purpose of accessing virtually any type of data that may be held in any one of millions of network-connected servers adapted for the purpose. 
   The most traditional network appliance used for navigating the Internet and downloading data therefrom is the personal computer (PC). More recently however, a host of other electronic communication devices have been adapted for network connection and navigation on the Internet. Some of these better known devices include cellular telephones, personal digital assistants (PDA&#39;s), pagers, and notebook and laptop computers. Some types of these appliances access the Internet via wireless connection. In other cases, data from the Internet is transmitted to such devices through a gateway to a network generic to the device. An example would be that of a cellular phone or pager capable of accessing e-mail and other Internet accounts information. 
   The Internet operates under a shared bandwidth protocol wherein data packets are transmitted whereby each transmission competes with all other current transmissions for available bandwidth resources. The total amount of bandwidth resource available to network appliances accessing the Internet is a function of network traffic, reliability and capability of lines, power of appliance processor, nature of intermediary network, and a host of other variables. It is not always possible to maintain an Internet connection for any reliable length of time considering all of these variables. Sometimes, there are periods when a device simply cannot gain access at all. In other cases physical connection is only possible on a periodic basis, and an appliance is therefore only intermittently connected. 
   Even with the more powerful and traditional PC&#39;s or notebook computers there may be times when available bandwidth suddenly drops resulting in a disconnect or “moof” as it is often termed. If a moof occurs when attempting to download data, another attempt must be made to re-access the network, re-navigate to the data source, and attempt a retry of the data download. This can be frustrating for users operating such devices as cell phones, pagers or PDA&#39;s which are already operating on high latency and/or low bandwidth connections. 
   Administrators of network equipment and connection architecture as well as companies that host such as WEB-based information services and the like are improving aspects of communication with various portable network devices by upgrading lines and equipment, developing better data compression and bandwidth reservation techniques and lobbying for more bandwidth for wireless intermediary networks. However, one area that has been largely overlooked is the very format and structures of data that is transmitted. For example, HTML or XML-scripted content is largely unsuitable for transmission under low bandwidth conditions to small portable devices. As a result, such devices having lower memory and operating under lower bandwidth resources are limited to certain types of data such as only e-mail or voice mail. 
   A system known to the inventor and listed under the cross-reference to related documents section provides a capability of automated login and navigation to Internet or other network-held sources written in HTML, XML, or other languages for the purpose of retrieving and presenting WEB summaries to subscribers according to client/enterprise directives. This service uses scripted templates prepared by knowledge workers using known site logic to enable navigation, not just to the site, but to specific content posted on the site. A parsing method is then used to identify appropriate data based on the provided script directives. 
   The data obtained by the above-described method is held in a server for user access (via PC), or pushed to a user (PC or alternate appliance) according to enterprise rules. The data is typically presented in the form of a WEB page made accessible to a user having suitable equipment for retrieving and viewing such pages. However, in another embodiment, the data is re-formatted when possible for transmission to a user specified Internet appliance such as a cell phone, laptop, PDA, etc. The user must first access the service using a device that supports a browser interface. Data is forwarded to alternate devices only on user request and assuming the user has configured his or her alternate device to the service. In order to receive some types of data, special software and/or hardware implementations must be made to the alternate appliances. 
   The above service does not support independent device access to the Internet (except for devices already capable of browser navigation), nor can it deliver certain content held in a format that is not readily convertible to a format generic to the software running on such alternate devices. Moreover much content that would be convertible may still overload the memory of certain alternate devices such as pagers or cell phones if additional data restructuring and synchronization steps are not taken. 
   It will be appreciated that there is a growing variety of existing and new portable-type devices that are being adapted for Internet access. Most of these devices communicate according to device-generic protocol and are unable to receive and disseminate certain other types of data under normal circumstance. Furthermore, low bandwidth connection states and limited memory provisions preclude many of these devices from broad Internet navigation capabilities and limit download capability in terms of time and type of data content that may be received. 
   What is clearly needed is a method and apparatus for intelligent restructuring of personalized data and, in some cases, generalized data from the Internet into model/device-specific data formats such that it may be easily made available for transmission to and presentation by a variety of known communication devices having either direct or indirect Internet connection capability. Such a method and apparatus would broaden the scope of Internet-sourced data types that a communication device could independently access and receive without requiring hardware or software modifications to such devices. 
   SUMMARY OF THE INVENTION 
   In a preferred embodiment of the present invention a system for retrieving and disseminating information records from Internet sources is provided, comprising a client device; and an intermediary server system including software between the client device and the Internet. The system collects a record specific to a client from an individual one of said Internet sources in a first form in which the record is recorded at the Internet source, transforms the record from the first form to a second form specific to an application other than an Internet browser application, the application executable by the client device, and transmits the transformed record to the client device for display in the application other than an Internet browser application executable by the client device. 
   In some embodiments the intermediary server system is connected to the Internet by an Internet-compatible link and the client device is connected to the intermediary server system by other than an Internet-compatible link. The other-than-Internet-compatible link may be an Internet Protocol Telephony link, a conventional telephony link operating by a conventional telephony protocol, a wireless cellular telephony link, or a wireless satellite-enhanced link. 
   In some embodiments there may be a personal computer (PC) connected to the intermediary server system by a conventional Internet-compatible link, and the client device connects to the PC by an other than Internet-compatible link, and wherein the system transmits the transformed record first to the PC which then transmits the transformed record to the client device. 
   Also in some embodiments the intermediary server system is a subscription system, and maintains client profiles for subscribers to the system, the client profiles including data relative to information destinations on the Internet for a specific client, data records to be retrieved from the destinations, and data forms for transformation of specific records. 
   In these and other embodiments the intermediary server system may maintain input and output templates for individual clients, the input templates having slots mapping records by type as received from Internet sources, and the output templates having slots mapping data records by type to be transmitted to the client, there being specific correlation between input template slots and output template slots for an individual client. Data forms for transformation to transmit to client devices may include one or more of conventional telephone protocol, Internet protocol telephony Protocol (IPNT), voice mail, e-mail, pager message, and records for applications common to personal digital assistants (PDAs), including one or more of appointment-book data records, memo-pad records, alarm records, and things-to-do records. 
   In some cases airline reservations retrieved for a client from the Internet are converted into multiple appointment-book entries displayable by an appointment-book application on a PDA, one appointment book entry for each individual flight in a reservation. In these cases there may be an alarm generated for each flight at a time preceding flight time for each flight. A different alarm interval may be used for domestic flights than for International flights. 
   In some cases billing schedules retrieved for a client may be converted into two or more records, one being a memo pad record detailing the details of the bill, and another being a things-to-do record to remind the client of the time the bill is due. In these cases an alarm record may be entered to generate an alarm prior to the time the bill is due, to remind the client that the bill is due. 
   There are a number of ways the system architecture might be arranged. In one alternative the intermediary server system is implemented in association with an Internet Service provider site. The intermediate server system may include an aggregation service for aggregating client-specific records prior to transmission to client devices. There may also be a synchronization service for keeping data on client devices synchronized with data from sources on the Internet and from the aggregation service. In one case the synchronization service uses an algorithm enabled to adaptively minimize round trip messages between the intermediary server system and the client device according to whether the client device is more limited by latency or bandwidth. The algorithm in some cases computes Cyclic Redundancy Check (CRC) codes for input and output records, and computes intersections between CRCs on records on the client device and at the aggregation service, the output of the algorithm being exactly the records that need to be sent to the client device and exactly the list of records that need to be deleted form the client device to keep the data sets in synchronization. 
   In another aspect of the invention a method for retrieving and disseminating information records from Internet sources is provided, comprising steps of (a) collecting a record in a first data form from an Internet source by an intermediary server system connected to the Internet; (b) transforming the record into a second data form specific to an application other than an Internet browser application, the application executable by a client device connectable to the intermediary server system; and (c) transmitting the transformed record to the client device for display with the client device connected by a data link to the intermediary server system. The method or a variation according to embodiments of the invention may be practiced with and within all of the apparatus and function variations described above. 
   In various embodiments of the present invention for the first time a server system is provided for retrieving and disseminating Internet-based data specific to individual clients, wherein clients may use devices that do not have or need an Internet connection capability or an Internet browser, but may still very clearly relate to the client all of the mined data, and wherein also the system can keep all data fresh and up-to-date for the client.

   DESCRIPTION OF THE PREFERRED EMBODIMENTS 
   According to a preferred embodiment of the present invention, a method and apparatus is provided that allows virtually any Internet-based data to be accessed, restructured, and then transmitted to a wide variety of network-capable appliances without requiring special software or hardware additions to the receiving devices, and in a form that the receiving device may display the data using an existing application on the device typically used for an entirely different purpose and function. Such method and apparatus is described in enabling detail below. 
     FIG. 1  is a basic overview of a communication network  9  wherein a data aggregation and tunneling service is hosted and operated according to an embodiment of the present invention. Communication network  9  comprises a data packet network  11 , which is the well known Internet in this example, an Internet Service Provider (ISP)  15 , and at least one exemplary wireless data network  13 . 
   Network  11  may be another type of data packet network instead of the Internet such as perhaps a private or corporate wide area network (WAN) as long as Transfer Control Protocol/Internet protocol (TCP/IP) or other suitable network protocols are supported. Network  11 , hereinafter referred to as Internet  11  for example purposes, is exemplified herein as a preferred embodiment because of the large public accessibility to the network. Such public accessibility lends to a preferred embodiment for hosting a large data-information service such as the service described in the cross-referenced application Ser. No. 09/323,598. 
   Internet  11  may comprise any geographical portion of the global network including such as data sub-networks connected thereto. Internet  11  has an Internet backbone  19  distributed throughout, which represents the many lines and connections making up the wired Internet. Three data servers  21 ,  23 , and  25  are illustrated within Internet  11  and connected to backbone  19 . 
   Servers  21 - 25  are, in this embodiment, file servers known in the art for serving data in such as hypertext markup language (HTML), XML, or other suitable languages associated with electronic information pages known as WEB pages in the art. It should be noted here that servers  21 - 25  are not limited to only serving WEB pages. In some embodiments, other data such as E-commerce data associated with on-line forms, digital authorization certificates, secure digital signature forms and the like, may also be held in such servers. Moreover, any one of servers  21 - 25  may be adapted as an E-mail server or may be subject to any other adaptation for serving data. 
   ISP  15  is adapted, in this example, for providing Internet connection services as known in the art. Illustrated within ISP  15  are a main connection server  33 , a mass data-repository  31 , and a modem bank  29 . Main server  33  is directly connected to Internet  11  as shown. Main sever  33  is adapted to perform normal Internet service routines as known in the art, and is additionally enhanced via a unique software instance  51  for enabling practice of the present invention. 
   In one embodiment, an additional server may be provided for executing software  51  and enabling practice of the present invention in conjunction with main server  33 . In another embodiment, more than one such server may be provided and adapted to execute individual instances of software  51 . The inventor illustrates just one server  33  and SW  51  for the purpose of simplifying illustration and deems it sufficient for the purpose of explaining the present invention. 
   Main server  33  is connected to a data center  37  by a data link  35 . Data center  37 , among other tasks, provides an ISP (Internet) interface to server  33  for various wireless data networks represented by network  13 . Network  13  is further characterized by the illustration of a communication satellite  17 , which provides satellite rebroadcast of uplinked data streams from data center  37  and a backlink to data center  37  as illustrated by a dotted double arrow. As previously described, network  13  may be plural in the sense that plural wireless data networks common to certain communication devices may accomplish an interface to ISP  15  (server  33 ) through such as satellite  17  or another type of wireless transceiver/receiver and data center  37 . 
   Within network  13  a variety of Internet capable appliances are illustrated. As examples there are a pager  39 , a notebook computer  41 , and a cellular telephone  43 . In this example, appliances  39 - 43  broadcast data, which is picked up by satellite  17  and relayed to data center  37 . Similarly, data arriving to satellite  17  from data center  37  is broadcast to and received by appliances  39 ,  43 , and  41  as illustrated herein with dotted double arrows representing respective two-way communication links. In the case of appliances  39  and  43 , network  13  might be a cellular network typically implemented for those devices. In the case of notebook  41 , network  13  may be a wireless Internet service using cellular or other suitable wireless technologies. 
   As previously described, main server  33  is also connected to modem bank  29  as is known in the art of land-line Internet access through an ISP. A personal computer (PC)  45  operated by a user/subscriber to the service of the present invention is illustrated as connected to modem bank  29  by an Internet connection line  49 . Line  49  may be a conventional telephone line, an integrated digital services network (ISDN) connection line, or any other suitable wired connection such as ADSL. A PDA  47  is illustrated by a dotted double arrow as having a wireless communication link to PC  45  as is common in the art of computer peripherals. 
   In the example of a subscriber service, data repository  31  would contain data about individual subscribers to the service of the present invention (user profiles and other user-specific records). Repository  31  may be an optical storage facility or any other convenient facility that is adapted for storing large amounts of data. Repository  31  is illustrated as connected to main server  33  by a data connection  27 . In this example, repository  31  is considered an off-line storage facility that is accessible to server  33 . In another embodiment repository  31  may be a part of server  33 , or in any other network-connected location such as on-line, or on a connected local area network (LAN). In addition to holding data specific to individual subscribers such as account information, address parameters, user ID and authorization data, repository  31  may also hold data gathered from such as Internet  11  before being delivered to or being accessed by users. 
   SW  51  executing on server  33  is provided for the purpose of enabling a unique data-gathering and tunneling service that allows users operating such as appliances  39 - 43 , and  47  to have structured access to data such as may be sourced in one of servers  21 - 25 ; and, to have the data re-structured in an intelligent fashion for delivery to a specific Internet appliance that may not be normally adapted for receiving and displaying the data. 
   Software  51  provides, in this case, a unique subscriber service hosted by ISP  15  in which the service may be accessed and utilized by using any Internet-capable appliance. For the purpose of discussion, an Internet-capable appliance shall include any electronic communication device capable of a direct or indirect (through a connected network) connection to a data packet network such as Internet  11 . Such devices may also include devices that may only receive data from such as Internet  11  as long as a separate device is used to access the service and upload a data request. 
   In practice of the present invention, a user operating such as cellular telephone  41 , for example, accesses ISP  15  from anywhere in network  13  through a wireless path, exemplified herein by satellite  17  to data center  37 , and registers a request for data. The data request in some cases may be manually initiated by a user, and in other cases automatically initiated on a periodic basis while the device is connected to the Internet. In some cases a request will he automatically initiated when the device connects to the Internet. 
   The nature of a request may vary under a broad set of rules set-up by a hosting enterprise (ISP  15 ) for types of requests. For example, one request may be for a data result of a site-specific search according to defined parameters such as was described in the characterization of a WEB summary disclosed in application Ser. No. 09/323,598. Another type of request may be for information about departure/arrival parameters and gate instructions associated with purchased airline tickets. Still another type of request may include a desire to access only the existing incoming mail from a certain individual or individuals. There are many possibilities. In a preferred embodiment a script for data requests may be a part of a user profile, and a single generic request from a user may trigger a variety of data searches and retrievals from Internet  11  on behalf of the user. 
   Data center  37  processes requests from network  13  and forwards them to main server  33  where they implemented. Various technological enhancements may be implemented in data center  37  to facilitate communication and interface capability with various portable appliances such as appliances  39 - 43 . One example would be to provide an interactive voice response (IVR) unit (not shown) that may take a vocal or touch-tone initiated request originating from such as cell phone  43 . Such an IVR may be included in data center  37  as a client interface. 
   The nature and content of a request from cell phone  43 , for example, is analyzed and restructured into an equivalent Internet Protocol (IP) request that can be uploaded into main server  33  over data link  35 . This process is, in a preferred embodiment, performed in data center  37  with the data center having access to a portion of software  51  dedicated to the specific function. In another embodiment, a specific portion of software  51  may be provided to be executable on a connected machine at data center  37  for the purpose of analyzing requests of varied protocol and restructuring them into requests that can be understood on server  33 . 
   Once a request from cell phone  43  is registered in main server  33  as an IP data request, data about the user is accessed from repository  31  for verification and authorization purposes. A scripted template supplied by a knowledge worker (not shown) is provided for accessing site logic during navigation and parsing as initiated by SW  51 . Such knowledge workers may be stationed at data center  37 , ISP  15 , or any other centralized location that is connected to the service by network connection. The scripting, navigating, and parsing technology is fully explained and detailed in the co-related application Ser. No. 09/323,598. However, further innovation is required in order to accomplish the goal of the present invention, which is the intelligent restructuring of data coming into and leaving from the service of the present invention. 
   In the present example a ready request is queued for execution by SW  51  according to on-demand or in a scheduled fashion. Server  33 , upon executing the request, navigates to one or more of servers  21 - 25  (for example, as representative of plural servers in the Internet) holding the requested data. The location of the data is then identified according to site logic provided in the scripted template. Located data is then parsed for specified content to be returned. The resulting data is aggregated in repository  31  if the request has a scheduled delivery or user-access time. If the return data follows an on-demand criteria, then it is immediately processed and delivered over data link  35  to data center  37  for further processing before being broadcast over network  13  to a user operating such as cell phone  43 . 
   In another aspect of the present invention, requests and return data may be registered and received by a user operating a PDA such as PDA  47 , which is a peripheral to PC  45  illustrated as wired to Internet  11 . In this embodiment, a user operating PDA  47  registers a request to PC  45 . The request is analyzed and uploaded to server  33  under control from PDA  47 . Additional processing concerning obtaining and returning information is the same as with previously described embodiment except that instead of using data center  37  as an interface, PC  45  acts as the interfacing machine. If requested data arrives to PC  45  in a format that is not discernable to PDA  47 , then data restructuring may be performed in PC  45  by a provided instance of SW  51  that is dedicated to the purpose. PDA  47  would require no modification in either hardware or software. In yet another embodiment the client machine may be PC  45 . 
   The method and apparatus of the present invention provides a unique capability of restructuring data in an intelligent way. That is, instead of simply converting one format of data into another, a first data set is analyzed and understood so that an alternate data set in a format specific to applications executable on a receiving device may be created that reflects the desired content and function of the first data set. More detail about how this is accomplished is provided below. 
     FIG. 2  is a block diagram illustrating an exemplary hierarchy and data transformation and flow existing between various components of the data aggregation and tunneling service of  FIG. 1 . The service of the present invention in a preferred embodiment comprises three basic component layers. These component layers are illustrated herein as layer  53 , layer  55  and layer  57 . Layer  53  is best described as a source-data interface layer. This portion of the service is dedicated to navigating to and obtaining data from Internet-connected data sources. Data sources (S)l-n are analogous to servers  21 - 25  of  FIG. 1 . It will be appreciated that the number of data sources that are available on a network such as Internet  11  ( FIG. 1 ) is vast. Data collected from Sl-Sn is continually aggregated into such as repository  31  ( FIG. 1 ) as indicated by the bi-directional arrows linking each Sl-Sn to aggregation service  54 . Aggregated data is tagged according to requesting user and target receiving device. 
   Layer  53  includes all of the means and processes required for locating and parsing user-requested data according to site-specific scripting techniques and funneling the collected data back to aggregation for storage under a user-specific ID parameters. Most, if not all of the data retrieved in layer  53  will be in the form of HTML, XML, or a similar protocol. Other than XML types of data may include various multimedia types associated with audio and video data, animated graphic data, or still graphic data. All data requested by any one user is aggregated under that user&#39;s ID parameters. 
   Data stored in aggregation is forwarded to layer  55  according to a pre-assigned schedule for processing. Layer  55  provides an internal process comprising data restructuring and primary interface capabilities. Data processing is the first phase of layer  55  as illustrated by process  56 . It is in the main the data processing phase that is unique and distinguishes the present invention from that disclosed in the copending and referenced application Ser. No. 09/323,598. 
   Instead of simply converting data from one language or format into another in an attempt to render it usable to a specific Internet appliance, the present invention seeks to rewrite original data in an alternate format or language that accurately represents the data presented in the original format in terms of content and function. Data expressed in this alternate format (standardized) is then restructured into the appropriate device-specific format for transmission. 
   To accomplish the above-described task, it is required that data obtained in layer  53  be at least machine-legible in its given language or format and understood by software  51 . SW  51  must also know parameters encompassing the formats and data presentation schemes of various software routines used in various Internet-capable appliances. For example, an HTML description of a flight reservation and gate instruction as presented on an information page (WEB page) would not be expressed as a text block in such as an electronic calendar, or a PDA. Rather, the same information would have to be restructured and expressed as a series of entries expressing time and date functions associated with the particular flight schedule. 
   In a preferred embodiment, an algorithm is employed as part of software  51  that can take information from provided input data-templates and restructure the information to fit pre-designed and associated output data-templates. For example, an input template is created for one or more records of network-based data. The input template renders the original data into a proprietary language similar to HTML and XML. The proprietary language or code expresses the original data in a standard format that may then be manipulated by algorithm. The input template holds the rendered data according to mapped slots. 
   An output template is created that is generic to the parameters and presentation scheme associated with a specific Internet-capable appliance that will receive the data record or records. The output template holds the specific slots wherein data will be rendered by the algorithm. The algorithm uses provided data-restructuring rules to identify data contained in an input data template and re-map it by matching the data to appropriate data-slots presented in an output data template. As a result, one or more input records (parsed and rendered data) will produce one or more output records (data remapped by algorithm). 
   Data templates as described above, are not analogous to logic templates described in the co-related application Ser No. 09/323,598. Data templates work in conjunction with scripted logic-templates used to find and parse the requested data. Input templates are request-generic while output templates are device-generic. For example, there are many variations of data formats and languages that can be used when presenting data on a WEB page. Therefore, an input template should be modeled to facilitate the specific data fields, language, and format in which requested data is expected to be found. In some cases, an input template may be enhanced to support a variety of differing formats and or languages, and be made to hold more slots for data not necessarily requested. The output template is device generic and contains only usable data-slots that may be presented on its associated device. 
   In one embodiment of the present invention, a knowledge base (not shown) could be provided as part of SW  51  and used to equate data parameters associated with frequently requested data types from a network to data parameters that are generic to various network appliances. In this method, categories and titles describing oft-requested data records such as flight reservations, account balance information, order status information, and the like are created, coded and stored in the knowledge base. Device-specific equivalents described as rules for presenting the type data to each specific model device are also stored in the knowledge base and equated. 
   When a data request comes in, a runtime engine (software application) takes the input data and finds the category and subtitle that matches it. Then the data presentation rules concerning the specific receiving device are matched from the knowledge base. In this way, appropriate output records may be created that are specific to the type and model of device that is targeted to receive the data. 
   In one embodiment, the knowledge base method is used in conjunction with the template/algorithm method. As use of the service progresses, the knowledge base is updated with new categories and subtitles associated with repetitive requests. The knowledge base may also be updated to reflect parameters associated with new types and models of network capable devices. There are many such possibilities. 
   Component layer  55  includes an interfacing data center such as data center  37  represented in  FIG. 1  and a desktop PC such as PC  45  of  FIG. 1 . Output templates contain device specific data that is ready for transmission to target devices such as devices  39 - 47  of  FIG. 1 . As output templates are completed, they may be held for requesting users at a storage facility (not shown) held in a data center, or pushed to requesting users based on the original request. Similarly, output records destined for such as Internet-connected PCs may be held therein for remote access, or pushed to requesting users operating peripherals such as PDA  47  of  FIG. 1 . 
   Component layer  57  represents various network capable appliances as described above and their associated transmission networks. Illustrated within layer  57  is a PDA with a remote (wireless) link to PC in layer  55  as shown by double-arrow connecting line. Also illustrated within layer  57  is a pager, a notebook, and a mobile phone, all having remote (wireless) connections to the data center represented in layer  55  as shown by the double-arrow connecting lines. The PC illustrated in layer  55  may be a desktop PC operated by one or more users. In another embodiment, it may be a powerful workstation shared by many users. The represented data center has all of the interface means required to bridge the appliances of layer  57  to the service. 
   It will be apparent to one with skill in the art that knowledge workers associated with creating input and output templates may perform their services from anywhere in a connected network without departing from the spirit and scope of the present invention. In one embodiment, input templates are supplied by knowledge workers associated with the service, while output templates are created by knowledge workers that are associated with various network hosting entities. 
   In another embodiment, the service of the present invention may be provided as a turnkey package wherein companies may set-up their own specific information services using the implements of the present invention. 
   It will also be apparent to one with skill in the art that an intermediary language derived in part from HTML and XML languages may be proprietary in nature and used as an intermediary data-conversion language between such as pure HTML and device specific protocol without departing from the spirit and scope of the present invention. Codes specific to such an intermediate language may be licensed to entities wishing to recreate the service for their own purposes. 
     FIG. 3  is a block diagram illustrating client request/result loop progressing through the various process phases of the service of the present invention in a preferred embodiment. In step  57  a client (user/subscriber) initiates a request for data. Such a request may be initiated from a network capable appliance like appliances  39 - 43  of  FIG. 1 . A client may also initiate a request from a standard PC such as PC  45  of  FIG. 1 , or a PDA such as PDA  47  of  FIG. 1 . Browser software of any sort is not required for a device to access the service. In this way, a low bandwidth device may be used to practice the present invention without depending on a parent or associated machine. For example, devices not having IP capability or navigational software would interface with such as data center  37  of  FIG. 1  in order to gain access. Appropriate equipment and means for bridging networks is made available in data center  37 . An Internet-capable appliance having a browser function and Internet connection capability may, of course, gain access through normal wired or wireless channels. 
   In step  59 , a request from a client is registered to the service. If the request is initiated from a device using a wireless network wherein a data center such as center  37  is the interface, then the request data may be converted from the protocol used by the requesting device to a suitable IP protocol for registering at a server such as server  33  in ISP  15  ( FIG. 1 ). If an Internet-connected PC or workstation is the interface, and a requesting device is a remote peripheral such as PDA  47 , then the original request will arrive already in suitable IP format. 
   In step  61 , the client request is compared against a database for additional information about the initiator of the request and, perhaps to finish the package by associating the appropriate templates to the request. The templates may be stored under specific user ID for repeat requests, and created new for cases where no template is available. This includes the scripting templates of Ser. No. 09/323,598 as well as input/output templates of the present invention. Once all information and planned routines are incorporated into a request, it may be queued for execution. 
   In step  63 , the service navigates to a data source or sources specified in the request on behalf of the client. Site-logic scripting provided by template, along with a data-parsing convention is used to locate and identify data associated with the client&#39;s request. Data sources will typically be information pages written in such as HTML or XML. However, this is not to be construed as a limitation. Other types of data as well as some multimedia content may be located and parsed according to site logic. 
   In step  67 , all data obtained in step  63  is aggregated and tagged according to a user-specific and device specific manner. In some cases the data found during navigation is simply stored in one location for a client with the stored data retaining it&#39;s original format. In another case, data is rendered to an intermediate form of it&#39;s original language for the purpose of providing a standard format from whence further re-structuring may occur. 
   In step  69 , aggregated data is restructured from its original format (if applicable) to it&#39;s final format (device specific) in preparation for transmission. In other cases, the data is stored for client access at his or her convenience. In a preferred embodiment, the above-described template method with algorithm is used. In an alternative method, a knowledge base technique is used. In still another embodiment, the two methods may be combined. It is assumed that by the time data restructuring occurs, an input and an output template containing the appropriate data fields pertaining to a target device have been provided. A software module (not shown) termed a data renderer converts the original data in aggregation into a suitable intermediary language that is understood to be standard to the system and compatible, in terms of further slot-mapping, according to any supported protocols specific to various network appliances interacting with the service. The intermediate language may be of a proprietary nature and licensed to other entities for use. In an embodiment wherein a knowledge base system is used, an intermediate language would not specifically be required. 
   The input template contains the rendered data in specific field-slots that are understood by the software algorithm. The algorithm also understands the field-slots associated with the output template. This is accomplished by creating specific rules for the algorithm to follow in operation. The algorithm re-maps the data from the input template into the field-slots in the output template according to the applicable rules. During this operation a second data renderer inserts and in some instances writes new data for insertion to specific field slots chosen by the algorithm. 
   In one embodiment, output templates may be provided with additional functional routines (based on the content of inserted data) that may be caused to activate a notification system or the like that is generic to a particular receiving device. For example, a round trip flight description may be rendered as a series of appointment book entries in such as a PDA. The additional notification routine in the output template may, according to the data, set an alarm or other audible alert to activate at a convenient time before the scheduled departure, as a reminder to the user. 
   In step  71  output records are delivered to specified devices through their respective interfaces and connected networks. In step  73 , a receiving appliance incorporates the data in usual fashion. Steps  71  and  73  may also be construed as steps for delivering and incorporating only updates to existing information. For example, the client send/return loop represented by steps  57  through  73  can be initiated for one or more requests and then be reactivated to receive periodic updates to already received data. For example, input and output records already sent to a client may be stored at the service for reference and tagged with client ID, time, date, etc. If an update request comes in from a client it can be noted in a new output template designed to carry only the new information. During the process at step  69 , the input template containing the previous data is compared to the input template containing the current data. The discrepant data in the new input template is remapped to appropriate field-slots in a new output template. In this way, the record only reflects the new data. In step  73  then, the new data overwrites the old data. Data obtained through the service may be routinely and periodically updated in a push or pull fashion. 
   In another embodiment, synchronization (updating) may be performed in step  63 . For example, a new update request may arrive wherein the previous input record is obtained and used to partially direct the function of parsing during the navigation process. The rule would in effect direct the parser to designate only data that is different from the old input template for collection. In this case, the algorithm may be employed in reverse fashion so that the intermediate language in an input template may be converted back to original language as seen by a parser. 
   In still another embodiment, the parsing engine may be equipped to read both languages. The parsing process may also include the algorithm function for re-mapping the data. 
   It will be apparent to one with skill in the art that the method and apparatus of the present invention may be applied to the method and apparatus disclosed in the co-related application Ser. No. 09/323,598 to provide a new and unique service without departing from the spirit and scope of the present invention. It will also be apparent that the method and apparatus of the present invention may stand alone from Ser. No. 09/323,598 as long as a suitable method for site navigation and parsing is included in the new service. 
   The service of the present invention may be adapted to serve specific wireless networks and client/devices connected to them. It may also be broadened to include many wired communication networks, including the Internet and PSTN networks. Conventions may be provided to such as SW  51  for the location, parsing and restructuring of virtually any type of data that may be held on a digital network. Even conventions such as video may be played and interpreted by the service for data mapping to provided output templates for creating records that reflect the content or at least a summary of content contained in the video. 
   Specific Examples 
   The present invention in certain embodiments is to be first brought to the public after the filing of the present patent application by a new Internet company named Yodlee.com in Sunnyvale, Calif. In the first implementations the service practicing the present invention is called Yodlee2Go. Specific features of the Yodlee2Go service are included here as further examples of the present invention. In these examples restructured information is provided to onto the Palm™, but this information could be inserted onto any other mobile device as well. Many cell phones, for example, have calendar and address book applications built in, so the restructured information could be inserted onto those devices as well, and into many others. 
   1. Travel Reservations. 
   If you book your travel reservations through an online travel agency such as BizTravel.Com or Travelocity.Com and you have added the travel site to your Yodlee home page, then your travel reservation information is synchronized onto your Palm, for example, into several places. For each travel reservation that you have:
         a. One record is entered into your Date Book for each “leg” of the flight. The description of the record contains the airline name on which you will by flying, your flight number, and the departure and arrival airport codes.   b. In addition, an alarm is automatically set to go off one hour before your flight time. You may change the alarm time for a particular flight by clicking on the “Details” button in your Date Book. (You may also change the default alarm time to be different than one hour by changing your Yodlee2Go preferences. This is described in Section x of this user manual.)   c. If you click on the “Note” button in the Details dialog box, you can view your confirmation number, the price that you paid for the ticket, the flight mileage, and the name of the travel agency with which you booked the flight.   d. Since Yodlee2Go knows which travel agency you booked the flight with, it synchronizes the contact information for that travel agency into your address book. This way, you will have the phone number of the travel agency with you if you run into problems at the airport. (Also, don&#39;t forget that you have your confirmation number in the note attached to the date book record!)   e. Finally, since Yodlee2Go inserts a memo into your Memo Pad application containing the entire itinerary for each of your flights.
 
2. Frequent Flyer Miles.
       

   If you have added any airline sites in the frequent flyer miles category onto your Yodlee home page, then all of your frequent flyer information is copied into a single memo in your Memo Pad application on your Palm. The memo is titled “Frequent Flyer Miles” and can be accessed by clicking on the Memo Pad application on your Palm. 
   3. Bank Statements. 
   If you do your online banking on the web, and you have added your bank&#39;s site to your Yodlee home page, then a summarized version of your bank statements will by synchronized into the Memo Pad application on your Palm. One memo will be created for each of your online bank accounts. Each memo will contain the balances in each of your accounts, and a total balance across all your accounts at that bank.&lt; 
   4. Credit Card, Telephone Statements, and other Billing Information. 
   If you have added any credit card or billing sites to your Yodlee home page, then this information will be synchronized onto your Palm to help you remember to pay your bills on time. For each bill, Yodlee2Go will insert one entry in your list of things to do in your To Do List application on your Palm device. The entry will contain the name of the company from which you received the bill, the due date, and the amount due by the due date. If you click on the “Details” button, and then click on the “Note” button to view more information about the bill. 
   5. Stock Portfolio Information. 
   If you have added your online stock broker (such as E*trade) onto your Yodlee home page, then your stock portfolio information will be synchronized onto your Palm device by Yodlee2Go. Yodlee2Go will create one memo pad entry in your Memo Pad application that contains a consolidated statement of all of your stocks across all online brokerages that you have added to your Yodlee home page. The memo is titled “Stock Quotes,” and also contains a summary of the total worth of all of your stock portfolios. 
   The methods and apparatus of the present invention have many broad applications and therefore should be afforded the broadest of scope. The methods and apparatus of the present invention are limited only by the claims that follow.
