         [0093]    The P/E Platform&#39;s hardware for the based on different devices interconnected, with the central element that the Mini Datacenter called P/E Server, server or P/E. 
     
    
     
       FIGURE DESCRIPTION 
         [0094]    In order to allow a better understanding of the invention, figures are included in annex, which represent exemplary realizations of the invention. The contents of such figures should not, however, limit the present invention. 
           [0095]    FIG.  1 —Schematic representation of the user&#39;s perspective on the system 
           [0096]    1. P/E Server 
           [0097]    The P/E Server: aggregates all forms of communication of information (static/dynamic content, documents, text, audio, video, conference, etc.) performed by the system, in the context of a work session or not; indexes, archives and acts as a distribution platform to all nodes of the platform and maintains their configuration; executes the control commands and applies and enforces security restrictions and rules of trust defined by users with sufficient privileges themselves; coordinates interactive work sessions between workgroups; serves as repository for content and document classification structures, while also allowing for their management. 
           [0098]    The P/E Server automatically determines the necessity of updating/upgrading platform components running/stored in the user&#39;s computer and automatically updates to all those systems according to the latest system specification. 
           [0099]    2. Interactive Workgroup Session Management 
           [0100]    Virtual and interactive work session between users, occurring in real-time and coordinated by the P/E Server. Includes the user&#39;s computers (learners, educators, assistants, etc.), without limitation of participants, and other audio/video/interactive peripherals. The P/E Server enforces all configuration structures defined by its own configuration (refer to Process Flow Diagram— 1 . 1  through  1 . 10 ). 
           [0101]    3. User Controls the Workgroup Management System from his Computer 
           [0102]    From his computer, the user executes the workgroup management system commands, in order to control the workgroup&#39;s virtual and interactive work session; all control commands are sent in real time to the P/E Server, which checks its internal configuration for actions to realize in that operation context and broadcasts the initial commands to all other users of that interactive work session; the P/E Server classifies, indexes and stores that information; users may also use the text/audio/video conference sub-systems to interact with other work session users. 
           [0103]    4. User Monitors the Workgroup Management System Session from his Computer 
           [0104]    The user&#39;s computer receives all work session contextual control commands emitted by users and routed thru the P/E Server (see item 3, above); if unblocked, the remote user may perform those same interactive work session control commands, for which the P/E Server also performs the same command control routing as listed above (item 3) to all other work session users, guaranteeing that content/information/documents flow bi-directionally within the work session and that all parties may interact with that data. 
           [0105]    5. Communication 
           [0106]    Wireless or wired communication devices guarantee data communication between the P/E server and all other system components (user&#39;s computers, interactive boards, etc.). Those other system components may or may not be physically separate from the institution in which the P/E Server is hosted. 
           [0107]    6. User Instructs Workgroup Management System Using the Interactive Whiteboard 
           [0108]    Through an integration layer, users may perform the same commands referred in items 1 and 2, above, from the interactive whiteboard, to control the P/E platform. 
           [0109]    7. User Monitors the Workgroup Management System Session from his Computer 
           [0110]    (Special case of item 4, above; please refer to that section) A user may control and interact with the platform independently of its physical location. Users which are not physically at the hosting site of the P/E Server are called Remote Users. He/she uses the workgroup management system to control interactive work sessions as if it was physically present. 
           [0111]    8. Portal 
           [0112]    User accesses the P/E platform&#39;s management and configuration sub-systems, through direct P/E Server access—refer to Process Flow Diagram (items  2 . 1  through  2 . 4 ). 
           [0113]    FIG.  2 —Process Flow Diagram (Schematic Representation) 
           [0114]    1. P/E Server Access Processes, Through the Workgroup Management System 
           [0115]    1.1. Workgroup Management System Access 
           [0116]    User issues the Workgroup Management System Start control command; optionally, the Server may do it automatically when a session is created, for which the user is being requested. 
           [0117]    1.2. User Authentication 
           [0118]    User authenticates him/herself in the Workgroup Management System. 
           [0119]    1.3. User Identification 
           [0120]    Based on his credentials and matching profile, the system identifies the user and presents him with a list of possible work sessions (based on platform&#39;s configuration at that time). Optionally, the user may create a session not previously configured. 
           [0121]    1.4. User Initiates Work Session 
           [0122]    User selects a work session and initiates it. 
           [0123]    1.5. Work Session Startup 
           [0124]    The system communicates the session start command to the P/E Server. The P/E Server obtains all session metadata (list of involved participants, initial or previous session content, etc.) and creates a virtual representation of that physical work session. Session metadata may be altered by the user at any time, while the work session is being held; the P/E Server automatically forwards the session created command to all authenticated users identified as being part of the work session (through configuration); the P/E Server makes all metadata and session content available to those users. 
           [0125]    1.6. External System Integration 
           [0126]    Session information is automatically shared with relevant external systems (school ERP systems, corporate intranets, etc.), through custom integration mechanisms. This process is only realized if the platform is configured and according to the specification provided by that configuration. This process is dependent upon the availability of such external systems. 
           [0127]    1.7. Virtual Board Activation 
           [0128]    The workgroup management system is correctly initialized and the P/E Server is able to monitor, control and broadcast all user initiated actions which occur in a work session context. 
           [0129]    1.7.1. Virtual Whiteboard Activation 
           [0130]    The user may resume a previous work session, which had been previously stored in his/hers computer or archived on the P/E Server. Commanding the P/E Server, privileged users may initiate/terminate the workgroup management in other user&#39;s computers if they are part of the same work session. 
           [0131]    1.7.2. Absence and Participation Recording 
           [0132]    Privileged session users may record the physical (or virtual) absence of another user, independently of its status before the system (the user may be logged on but still be marked as absent from the work session); the P/E Server automatically forwards the user status (both physical/virtual absence and participation) to all work session users. At any given time, users may invoke a command to require contribution or participation in the work session (may be referred to as “raising the hand”); that command is routed to all users by the P/E Server and a privileged user may allow the requesting user to participate, by unblocking its work session (this command may unblock one or several users at time); that user may also restrict users from participating in the work session (non-privileged users are blocked from participating by default); finally, the privileged user may attribute a score to each user&#39;s participation individually. The P/E Server tracks and broadcasts all these commands, in real-time, to all work session participations. 
           [0133]    1.7.3. Virtual Board Interaction 
           [0134]    Privileged users create and delete virtual work areas for interaction with other users, in the context of their current work session; the user may switch between previously created virtual work areas; all users share the same virtual work areas and interact with their current virtual work area; in response to a switch virtual work area command, the P/E Server may automatically change the virtual work area for any user in the work session; privileged users may delegate work session control to any other privileged user—the P/E Server will then recognize the new user as its main controller. 
           [0135]    Privileged users may assign specific work areas to other users or groups of users, with the intention of realizing specific collaborative work tasks (respond to questionnaires and exercises, content production and annotation, etc.). Unblocked users may use their computer and/or external interactive devices (such as interactive boards, digital pens, etc.) to add, change and remove virtual content (write, draw, add images, audio, video, etc.) from their assigned work areas, concurrently. 
           [0136]    1.7.4. Attach/Detach Associated Documents 
           [0137]    Unblocked users choose documents of relevance to the work session and attach them to the work session; the user may also remove those documents at any time. 
           [0138]    1.7.5. Dynamic Content 
           [0139]    1.7.5.1. Add/Remove Content 
           [0140]    Users navigate the P/E Server archive structures and may include content located there, directly into the virtual work session. This content may come from the user&#39;s private managed content areas, public navigable structures, and/or public content galleries. 
           [0141]    1.7.5.2. Interact with Content 
           [0142]    Dynamic content included in the work session may behave dynamically, according with the work area where it&#39;s included and, also, the computer where it&#39;s running (all users share the virtual work areas, but dynamic content is allowed to recognize and interact with each specific user independently). Dynamic content may expand the system&#39;s capabilities beyond its initial capacity; when interacting with dynamic content, users may activate features that also trigger other types of non-predefined actions; dynamic content may also use the P/E Server to interact with remote users of the work session. 
           [0143]    1.7.6. Collaboration 
           [0144]    1.7.6.1. Present Exercises/Exams 
           [0145]    Using the interactive and collaborative capabilities of the workgroup management system, users pose questions, layout exercises and/or start discussion threads (other collaborative scenarios are also possible). 
           [0146]    1.7.6.2. Respond to Exercises/Exams 
           [0147]    Users which are required or want to respond/contribute to exercises/discussions can do so, using their computer and the interactive and collaborative functions of the workgroup management system. 
           [0148]    1.7.6.3. Display Results 
           [0149]    If so desired, users may inspect the discussion thread or exercise resolution areas to check their result and may attribute a given score to that user&#39;s performance while resolving the problem at hand. 
           [0150]    1.7.7. Work Session Management 
           [0151]    1.7.7.1. Access User Profile 
           [0152]    Privileged users access other users public profile and are presented with their public personal details and platform usage status (the definition of both “public” and “usage status” depends on the dynamic configuration of P/E Server). 
           [0153]    1.7.7.2. Add/Remove Work Session Participants 
           [0154]    After accessing their public profile, privileged users may request the P/E Server to add or remove other users from the virtual work session. The P/E Server forwards this request to those users and mandates a positive or negative response, adding those users in the affirmative case (no acknowledgment is necessary for user removal from the work session). 
           [0155]    1.7.8. Conference System Interaction 
           [0156]    The platform&#39;s real-time text/audio/video conference system is used as an auxiliary communication mechanisms and remote collaboration tool, within the work session (apart from traditional methods, which include: physical conversation, landline or mobile phone calls, email, etc.) 
           [0157]    Privileged users control the platform&#39;s conference system; using his/hers computer, he/she may initiated and terminate a conference session within the work session. After it&#39;s activated, all other work session users may require access to the work session&#39;s conference system; privileged users are responsible for allowing or denying those requests. Privileged users also manage the focus of attention of conference sessions (who interacts with whom). 
           [0158]    1.8. Workgroup Management System Broadcasts Interaction/Activity 
           [0159]    The P/E Server automatically broadcasts every work session activity to all work sessions users, independently of their physical location, in real-time. It also automatically indexes and archives all content produced within the work session, for future reference. That information is made available in the P/E Server&#39;s content management system (every work session object is classified individually, e.g., every text block, audio/video clip, etc.). 
           [0160]    1.9. Conference System Broadcasts Interaction 
           [0161]    Also in real-time, the workgroup management system&#39;s text/audio/video conference sub-system broadcasts all interaction recorded within its boundaries to all participants of the work session&#39;s conference (not all users of the work session). 
           [0162]    1.10. Exit from Workgroup Management System 
           [0163]    User issues an exit command, which is forward to the P/E Server, informing is desired to leave the work session; the P/E Server dynamically determines if the work session should be terminated or if it should continue executing. 
           [0164]    2. P/E Server Information Management Processes 
           [0165]    2.1. P/E Server Access 
           [0166]    User access the P/E Server through internet or intranet connectivity. 
           [0167]    2.2. Authentication 
           [0168]    User provides his logon credentials to the P/E Server, which validates and authenticates the user credentials. The user&#39;s profile is loaded by the P/E Server, in order to customize the system&#39;s capabilities for that particular user. 
           [0169]    2.3. Content Management Processes 
           [0170]    2.3.1. Archive Documentation 
           [0171]    The user is allowed to archive electronic documents of any type; when archiving a document, the system requires the user to provide sufficient metadata to classify that document in accordance to the metadata structure defined as part of the P/E Server&#39;s metadata configuration services. The system automatically stores the document in the appropriate location (once again, according to the system&#39;s configuration), versions it and, optionally, signs it with the user&#39;s digital certificate information; if so configured, the system may also initiate a set of actions (workflows) in response to that document being stored in the system (examples of actions are: sending emails, creating other documents; creating tasks for users to execute, etc.). 
           [0172]    2.3.2. Access (Meta) Information Structures 
           [0173]    The user navigates the P/E Server&#39;s indexing and classification structures or searches its contents by inputting complex textual expressions and operators (“this and that”, “this or that”, “this contains that”, etc.). In response to this kind of input, the server presents the list of content that matches the given criteria, independently of location. Upon discovery of the desired electronic document, the user may read, write or activate it and/or access its metadata information (creation date and user, type of document, etc.). Optionally, the user with sufficient privileges may alter the metadata associated with the given document; metadata changes will result in a re-classification of the document, which might trigger a relocation of that given object. This process might be replicated for each document version in the system. 
           [0174]    2.3.3. Personal Area Management 
           [0175]    User accesses his/hers personal area and manages his/hers personal data (access credentials, address, custom profile data, contact information, etc.) and adds/removes collaboration areas (blogs, wikis, newsletters, etc.) to interact with other users (non real-time collaboration). 
           [0176]    A personal messaging system allows the user to send direct asynchronous messages (not in real-time) to others users and respond to messages those users send him; all messages are indexes, stored and routed by the P/E Server; the user can delete messages at a later time. 
           [0177]    2.3.4. Manage Users 
           [0178]    Privileged users (P/E Server administrators) add or remove users to the system, configure their access credentials and base profile and block or unblock them from accessing the system; the system automatically enforces the necessary security rules and access restrictions based on the user&#39;s new or changed profiles, possibly reclassifying already existent information. All sub-systems are automatically informed of this change and reconfigured accordingly. 
           [0179]    2.3.5. Manage Content 
           [0180]    Users manage content they are responsible for (which they&#39;ve created or for which other content owners have relinquished its control); they add and remove content (new or different versions of old content) from their personal content gallery or from the P/E Server community driven galleries (to which privileged users control access—who can add, remove and/or change content); that content is automatically made available in the workgroup management system for dynamic inclusion in virtual work sessions; the user manages the metadata of all content in its personal galleries, while only steering the P/E Server&#39;s automatic classification infra-structure, if the content is to be made public (placed in public content galleries). 
           [0181]    2.3.6. Manage (Meta) Information Structures 
           [0182]    Privileged users configure the system&#39;s document/content classification structures by adding or removing content repositories and relocating content. 
           [0183]    2.4. Exit P/E Server 
           [0184]    The user closes his/hers P/E Server session. 
       
    
    
     DETAILED DESCRIPTION OF INVENTION 
       [0185]    The Mini-DataCenter is the centerpiece and the core of the whole P/E platform. 
         [0186]    This is a piece of hardware that includes different electronic components that ensure the functioning of the whole P/E platform, and therefore all its sub-systems and the procedures that it implements. 
         [0187]    Physically, this equipment is a rigid box where all electronic devices described below are mounted. 
         [0188]    It is designed according to a set of requirements that allow its easy and intuitive installation and use. 
         [0189]    The aim is to provide a base P/E platform as an integrated ready to use product, featuring a system that allows self-installation. 
         [0190]    The Mini-DataCenter or P/E Server has the capacity of processing, manage content and logically file digital information. 
         [0191]    The Mini-DataCenter contains a set of components necessary to the management of an infrastructure which mandates high security standards. 
         [0192]    It also features remote access, in order to be remotely maintainable. 
         [0193]    Mini DataCenter Components 
         [0194]    1—Processing Units 
         [0195]    The P/E Server includes a set of servers suitable for Data Centers with redundant power supplies, storage and ventilation. 
         [0196]    2—Storage Units 
         [0197]    The P/E server includes variable capacity storage, scalable and configurable according to the needs of implementation. 
         [0198]    3—Storage 
         [0199]    The data storage is guaranteed by a storage component that allows you to have large amounts of information with redundancy. This storage component provides scalability to the P/E Platform and its hardware failures. 
         [0200]    4—Communications 
         [0201]    The P/E Server communicates with other devices that integrate the P/E Platform with high speed networks and centralizes all communications. The hardware has a firewall that performs real time control over all transmissions, filters that traffic, according to permissions and access levels configured in the P/E Server. 
         [0202]    5—Energy 
         [0203]    The power supply is a module (UPS) that ensures that the system is not susceptible to external power outages, and, thus, the ability to withstand electrical surges and momentary power failures. 
         [0204]    In case of continued power failure, it will automatically shutdown the system, ensuring that information is stored before turning the system off. 
         [0205]    The UPS is connected to the monitoring system to check the system status. 
         [0206]    6—Safety Components 
         [0207]    6.1. Microphone 
         [0208]    There is a microphone on the front of the P/E Server that allows you to check and record the presence of people. Through this feature, the P/E Server will be able to monitor the sound environment of the classroom, and also send alerts to start a conversation with the support team. The simultaneous use of voice and image allows the user to make contact with the support team, via the existing digital communication infra-structure. 
         [0209]    6.2. Video Camera 
         [0210]    The camera positioned in the Front Panel of the Mini DataCenter allows detection of movement. Once movement is detected, the system starts to record and sends the information to an external location, possible future investigation. This camera also allows to start a conversation with support teams. 
         [0211]    6.3. Servomotor-Equipped Access Door 
         [0212]    Using a door with servomotor, it is possible to protect the access to the machines through an integrated security system, which means that the door opens only after the user has been identified. 
         [0213]    6.4. RFID 
         [0214]    The RFID system requires a technician to be positively identified, prior to any intervention. If anyone tries to access a system component while not identified, the system will immediately block itself. 
         [0215]    6.5. Personal Identification System 
         [0216]    Personal identification systems based on biometric technologies (voice, fingerprint, iris or facial recognition) can be used for personal recognition, to protect the equipment from being accessed by non authorized personnel. 
         [0217]    6.6. Laser Beams 
         [0218]    If the equipment is forced, there is a laser detection system that covers the entire perimeter of the box. The beam is invisible, but if it is traversed by any object, it emits an alarm and initiates procedures to block machine access and destructs encryption keys, making it impossible to access its configuration information. 
         [0219]    6.7. Chip Data Encryption 
         [0220]    The data stored in the system is encrypted by a chip that contains an encryption certificate. By encrypting data the information is made secure against possible attempts of theft or fraud. 
         [0221]    7—Integrated Air Conditioning Module 
         [0222]    The air conditioning module is an optional system that is installed on top of the Mini DataCenter. All external structures are positioned to ensure that the cooling system is completely closed. 
         [0223]    The air conditioning is extremely important so that the server can be used in locations of high heat, high levels of humidity or other adverse conditions to proper functioning. 
         [0224]    8—Soundproof Boards 
         [0225]    Allow noise emissions to be kept under control and in accordance with the standards of hygiene and safety at work. 
         [0226]    9—Monitoring, Security and Assistance 
         [0227]    9.1. Monitoring 
         [0228]    The Mini DataCenter has a specific component for monitoring; this component has the function of verifying all of P/E platform&#39;s hardware and software, allowing the immediate deployment of technical assistance. 
         [0229]    The information about the state of the machine is available on an external display located in the exterior of the P/E Server. 
         [0230]    By monitoring indicators, it&#39;s possible to identify the operational status of the machine, enabling preventive maintenance and optimization of resources/performance. 
         [0231]    All monitoring records can be centralized, in order to be analyzed remotely via public or private communication networks. 
         [0232]    9.2. Assistance 
         [0233]    Assistance may be local or remote. 
         [0234]    By using the external screen on the Mini DataCenter, the user can submit a direct request for technical support. 
         [0235]    The user can choose to provide the support technician with the remote equipment usage and monitoring records (logs), so that he can better analyze the problem. 
         [0236]    By using the external screen, camera and microphone built in the machine, it is possible for a user to interact with the remote support team and simultaneously proceed with the instructions for correcting anomalies. 
         [0237]    9.3. Security 
         [0238]    The physical access to the P/E Server can be made with different degrees of security clearance, according to the following procedure: 
         [0239]    The technician will physically access the P/E Server and will insert his personal code on screen, to acquire access to a secondary identity matching mechanism. If the code is correct, the system will require the technician to input his/hers credentials through the personal identification system (biometric or other). 
         [0240]    After confirming the technician credentials, the Mini-DataCenter door will open and the laser detection system will be turned off. 
         [0241]    II—Peripherals that Interact with the P/E Server 
         [0242]    1—Interactive Boards 
         [0243]    Interactive smart boards are integrated with the P/E Server as external peripherals that are part of P/E Platform. 
         [0244]    The Interactive smart boards are interconnected with a control computer that will ensure the authentication and integration with the P/E platform through a set of identification elements composed of a username and password, or alternatively, a biometric recognition system. 
         [0245]    2—Work Computers 
         [0246]    The work computers are connected to the P/E Server through a wireless network or via an internet connection. 
         [0247]    Regardless of the location of the machines, they will always have to be authenticated before the P/E Platform so that they can access the system. 
         [0248]    Using the P/E Platform&#39;s Command System (see below) each user is validated and all the features to which he has access are available automatically. 
         [0249]    3—Microphone 
         [0250]    Using a microphone, it&#39;s possible to record work session sound. For instance, a teacher may record the class so that it might be heard again later by his students. 
         [0251]    4—Camera 
         [0252]    Using a camera enabled device, an entire work session can be recorded and replayed at a later time. 
         [0253]    5—Video Conference System 
         [0254]    Electronic system that enables the capture and dissemination of text, sound and image in real time, used also to record and store all interaction between the various users of the P/E Platform. 
         [0255]    6—User Geo-Positioned Location System 
         [0256]    The system monitors user location through geo-positioning enabled access card usage and emits alerts (sound, email, etc.) when location boundaries are exceeded. 
         [0257]    7—Access Point 
         [0258]    By using Access Points it is possible to integrate all the components in the network without the need for wires to link the physical infrastructure of the P/E Platform. 
         [0259]    8—Other Peripherals 
         [0260]    The entire platform is designed to grow and integrate new components, such as peripherals tailored to handicapped individuals. 
         [0261]    III—Logic Infrastructure 
         [0262]    1—P/E Platform Network 
         [0263]    All of the P/E Platform is designed in a distributed way, allowing new nodes to be added, creating a distributed network where rules of trust and responsibility can be defined to enforce virtual boundaries. Each node of this network is called P/E Platform Command System. 
         [0264]    P/E Platform network is formed by all connected Command Systems. 
         [0265]    2—Distributed Communication 
         [0266]    Messages are routed between network nodes, and all communication must flow between the P/E Server and the appropriate P/E Platform Command Systems. 
         [0267]    3—P/E Platform Administration 
         [0268]    The P/E Platform&#39;s Management System is responsible for enabling capabilities such as: managing users, creating user groups, configuring the accessibility and extensibility functions, installing sub-systems, etc. 
         [0269]    It is also this system that defines the rules of trust between users of the P/E Platform, allowing the creation of structured networks. 
         [0270]    4—Content Management System 
         [0271]    The P/E Platform includes a Content Management System that provides: 
         [0272]    A Notification Control System for content changes—a System for Automatic Content Distribution between servers, which ensures that contents are continuously synchronized between different platforms, allowing optimized and local access to contents. 
         [0273]    The Content Management System is a structured, classified and indexed mechanism, allowing efficient information searches, document versioning and also life cycle management, audit and tracking for each individually stored data unit (content/electronic document). 
         [0274]    The Access Control System allows the sharing of information across different users in a fully secure environment. 
         [0275]    It allows the creation of virtual workspaces and provides users with a personal work area, so it is unnecessary to save documents locally until the document is complete; all documents are guaranteed to remain available on the P/E Platform, for their entire lifetime, surviving local data corruption and loss of information (accidental deletion, for instance). 
         [0276]    Through integration with the Microsoft Office platform or other WebDAV enabled tools productivity can be increased. 
         [0277]    5—Integration 
         [0278]    P/E Platform was designed with an open architecture to allow the subsequent integration of new systems. 
         [0279]    By using the Interactive Workgroup Management System it is possible to integrate interactive contents, such as educational games, educational quizzes, dynamic meeting agendas, to-do lists, etc. 
         [0280]    The P/E Platform comprises a set of Development Applications Tools that allow the creation of more dynamic content, which may be made available directly on the P/E Platform. 
         [0281]    6—Internationalization 
         [0282]    The P/E Platform supports several languages and may be configured to support any other. 
         [0283]    IV—Procedures Implemented by the Platform 
         [0284]    1—Official Guides in Digital Mode/Collaboration Platform 
         [0285]    The P/E Platform also provides a set of collaboration tools such as: 
         [0286]    Blogs 
         [0287]    Wikis 
         [0288]    Forums 
         [0289]    Notifications 
         [0290]    Alerts 
         [0291]    SMS 
         [0292]    Newsletters 
         [0293]    News 
         [0294]    Calendars and Events 
         [0295]    2—Structure Explorer 
         [0296]    This system allows to create, index, use of models and storage in structures of complex contents in a simple and direct way. 
         [0297]    The Structure Explorer also includes an automatic structure generator, called Structure Generator sub-system. This system allows replication of content and file structures previously defined through rule-based replication. 
         [0298]    3—P/E Platform Command System 
         [0299]    The P/E Platform Command System ensures that all components have the functionality needed to authenticate, authorize, report, store information, install and run applications and modules and upgrade itself. 
         [0300]    The top-level Command Systems have the ability to register other sub-system commands. The sub-systems request the top-level Command System all the information needed to know how to self-install and customize themselves according to their credentials and functions. 
         [0301]    This is the only system component that has to be initially available on any computer before it is connected to the P/E Platform. 
         [0302]    The top-level Command Systems have the ability to create rules of trust between them. They enforce communication rules between sub-systems, in order to create a fully secure network of components. 
         [0303]    Execution of each of the P/E Platform application components is guaranteed by the Command System. 
         [0304]    4—Application Selector 
         [0305]    The P/E Platform has its own system of software component installation, upgrade, initialization and execution. 
         [0306]    Application Selectors also serves as an entry point to the Application Store and the System Application Launcher of the P/E Platform&#39;s Command System. 
         [0307]    5—My Profile 
         [0308]    The Profile Management System (My Profile) is completely extensible, by allowing the dynamic creation of properties to identify users. 
         [0309]    Each user&#39;s profile supports the definition of public and private data and who as access to that data. P/E Platform access levels&#39; can be customized per user profile. 
         [0310]    The Profile Management System software component allows privileged users to access and maintain the user profile pool and offers users the necessary functionality to manage their own profile. 
         [0311]    Examples of public profile information include: personal interests, birthday date, internet contact information, etc. The Profile Management System also allows the creation of customizable “social” areas or pages that allow visualization of the user&#39;s public profile information in a user friendly environment. 
         [0312]    The Allocation System Certificate of Competence allows schools to create certificates that are forever associated with the student&#39;s profile. For example you can have a certificate indicating that the student passed a particular exam or test. 
         [0313]    These certificates, as all other properties of the profile of the P/E Platform can be exported between systems and monitor its user where the profile is sent to other platforms P/E. 
         [0314]    6—My Location 
         [0315]    The My Location System is based on the use of geo-located cards. 
         [0316]    This system lets privileged users know where other users of the P/E Platform are physically located, by using a system of individual cards that send physical location information to the P/E Platform. 
         [0317]    The system automatically emits alerts when users move to external locations or inside/outside configured coverage areas. 
         [0318]    The Alert Registration System allows users or software components to be configured as recipients of alert messages whenever certain events happen. 
         [0319]    7—My Gallery 
         [0320]    The My Gallery System is integrated with the Workgroup Management System and allows the creation of content gallery that can be used in the context of the Workgroup Management System virtual work sessions. 
         [0321]    This system may include either or all of: pre-defined content, user generated content or third-party custom developed content. 
         [0322]    8—Application Store 
         [0323]    The Application Store is the System that allows the delivery of applications to users. 
         [0324]    This System archives and indexes all applications and functionalities that the user has access according to his particular profile. 
         [0325]    9—Interactive Workgroup Management System 
         [0326]    The Workgroup Management System is the system that enables real time management and sharing of content between P/E Platform users, storing all exchanged information for offline distribution and use later use. 
         [0327]    Creation of a Workgroup Management System work session allows for multiple users (e.g., students) to work on the same information, while the work session is being controlled by other privileged users (e.g., teacher). 
         [0328]    The Workgroup Management System has the ability to start distributed work sessions among different users according to their different profiles. 
         [0329]    Privileged users (e.g., teachers) may force the execution of the Workgroup Management System on other users (e.g., students), according to their profile per work session. 
         [0330]    This system is managed by the P/E Platform and allows immediate, managed, real time interaction, between various peripherals that may be connected to the P/E Platform (e.g., web cameras, interactive smart boards, etc.). 
         [0331]    This system has a storage component that is integrated with the metadata management system and which indexes all content generated in the work session, as well as managing its logical location within the P/E Server Storage System. 
         [0332]    The metadata system is extensible, allowing new components to extend document/content classification properties. 
         [0333]    The Workgroup Management System allows work session privileged users to request remote participation from other work session users. The contrary is also true. 
         [0334]    All interactions between Workgroup Management System are recorded for auditing, which also allows replaying the work session at a later time. 
         [0335]    The Workgroup Management System is extensible with new functionality and features according to the context in which it is working (ex. workshops, lectures, training sessions, etc.). 
         [0336]    Computers of users in a Workgroup Management System work session can be are locked and unlocked remotely from a privileged user&#39;s computer. 
         [0337]    Work sessions have an infinite content area available. Zoom and pan functionality allow for the entire content area to be made available. 
         [0338]    As said, the Workgroup Management System may include interactive and dynamic content, which may provide users with enhanced functionality. That content and any actions it triggers in the work session context will be replicated in real-time to all other work session users. Content may interact with other content, participants (through any input method available on the user&#39;s computer) and any other of the platform&#39;s software components (if so allowed by the platform&#39;s configuration). 
         [0339]    The system is agnostic to the user&#39;s location, which permits remote work session access through an Internet connection. 
         [0340]    The system of audio and video recording and streaming allows users who are attending class remotely to listen and act as if they were physically present. 
         [0341]    The Speech Recognition System allows automatic transcription of what is being captured in the user&#39;s computers audio input devices, in any physical location, to the work session. Synthesized speech can also be constructed and broadcast, from text written in a work session. 
         [0342]    The creation of user groups within the Workgroup Management System&#39; work session enables separate working groups to have separate access to information, within the context of a work session. 
         [0343]    10—File Formats 
         [0344]    XML is the basic content registration format. This means that various application development tools may be used to access produced content. 
         [0345]    Additionally, the P/E Platform allows storing and indexing of contents regardless of its format (based on the Metadata Management System). 
         [0346]    Also, the Workgroup Management System may include content in several formats, either as an attached document or virtual content include directly into the work session. 
         [0347]    11—Dependency Management System 
         [0348]    This system allows the management of dependencies between the P/E Platform&#39;s components. 
         [0349]    This system allows replication of dependent files without massive information replication, by continuously monitoring the status of the components previously installed. 
         [0350]    12—Application Storage System 
         [0351]    This system is responsible for managing the storage of all applications that ensure the functioning of the P/E Platform. 
         [0352]    13—Application Development Toolkit 
         [0353]    P/E Platform contains a set of application development tools that allow new applications to be developed and integrate with existing ones. 
         [0354]    The development tools of the P/E Platform also allow the development of contents that can be continuously incorporated into the Workgroup Management System and replicated in real time to all users.
