## Background
CROSS-REFERENCE TO RELATED APPLICATIONS
This application claims the priority of Korean Patent Application No. 10-2005-0088681, filed on Sep. 23, 2005, in the Korean Intellectual Property Office, the disclosure of which is incorporated herein in its entirety by reference.
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present general inventive concept relates to a document distribution system and method using a World Wide Web Distributed Authorizing and Versioning (WebDAV) protocol, and more particularly, to a system and method of transmitting a document to a WebDAV server using a WebDAV protocol and distributing the document to several clients.
2. Description of the Related Art
World Wide Web Distributed Authorizing and Versioning (WebDAV) is an Internet engineering task force (IETF) standard for supporting collaborative document authoring on the Internet, and is a Hyper Text Transfer Protocol (HTTP) extension that allows multiple authors to collaboratively edit and manage files remotely on the Internet. It is expected that WebDAV can satisfy an initial goal for collaborative web authoring by adding a write property to a read property of the HTTP. It is also expected that WebDAV allows the multiple authors to collaboratively work on a document on the web in the same manner as performed through the intranet of a company.
Conventionally, a file transport protocol (FTP) has been widely used to transfer files in a document distribution system. To transfer the files in the conventional document distribution system, the FTP has been additionally installed in a server. Moreover, the FTP does not have functions to edit original documents to be transmitted and to set various properties of the document. Thus, a document distribution system using a WebDAV protocol having the above functions is needed.
SUMMARY OF THE INVENTION
The present general inventive concept provides a method and apparatus to transmit a document to a specific folder of a document distribution system using a World Wide Web Distributed Authorizing and Versioning (WebDAV) protocol and to distribute the document to several clients in order to configure the document distribution system without installing an additional file transmission protocol (FTP) in a server and transmit the document after setting various properties of the document without editing the document.

Reference will now be made in detail to the embodiments of the present general inventive concept, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the like elements throughout. The embodiments are described below in order to explain the present general inventive concept by referring to the figures.
FIG. 1 is a block diagram illustrating a document distribution system using a World Wide Web Distributed Authorizing and Versioning (WebDAV) protocol, according to an embodiment of the present general inventive concept. Referring to FIG. 1, the document distribution system using the WebDAV protocol includes a first client 100, a WebDAV server 110, a second client 120, and a third client 130.
The first client 100 transmits a document to the WebDAV server 110 using the WebDAV protocol. In Furthermore, the first client 100 can transmit the document to a predetermined directory of the WebDAV server 110.
A user can set document information and a document level property of the document through the first client 100 or a web server, such as the WebDAV server 110, connected to the first client 100.
FIG. 2 is a view illustrating a user interface to set a document storing location and the document information of a document in the document distribution system of FIG. 1. Referring to FIGS. 1 and 2, the user interface includes a document storing location interface 210 to set the document storing location and a document information interface 220 to set the document information. The user interface to set the document storing location 210 may include a server uniform resource locator (URL) or a directory of the WebDAV server that can be set to store the document. An author's name, an author's e-mail address, a document level, and a date of creating the document may be set as the document information, which is set through the document information interface 220. In addition, a brief memo regarding the document can also be stored through the document information interface 220. The user interface may be generated by either one of the WebDAV 110 and the first client 100. A user may input data to the user interface.
The WebDAV server 110 transmits the document previously transmitted to the URL or the directory of the WebDAV server to a directory that is designated based on the document information and document level property.
The second and third clients 120 and 130 can access the designated directory based on the document information and the document level property according to authority information thereof.
FIG. 3 is a flowchart illustrating a method of distributing a document using a WebDAV protocol such as the one illustrated in FIG. 1, according to an embodiment of the present general inventive concept
Referring to FIGS. 1 through 3, the first client 100 scans data to be transmitted to the WebDAV server 110 (Operation 300). The data may be a document having document information and a document level property. The first client 100 selects the data to be transmitted to a document distribution system (Operation 310). The first client 100 may use the user interface of FIG. 2 to select the data. The first client 100 determines whether to use the existing document level property and document information of the data to be transmitted (Operation 320). When it is determined that the first client 100 does not use the existing document level property and document information, but instead decides to update the data to a new document level property and document information, the first client 100 changes the document information and document level property (Operation 330). When setting the storing location and information of the data, the server URL and the directory of the WebDAV server may be set to store the data. Also, the author's name, the author's e-mail address, the document level, and the date of creating the document can be set as the document information. In addition, the brief memo regarding the data can also be stored along with the document information.
When it is determined that the first client 100 uses the existing document information or the new document information, the first client 100 transmits the data and the document information to the predetermined directory of the document distribution system (Operation 340).
The WebDAV server 110 determines the document level property based on the document information of the transmitted data, and re-transmits the data to directories designated according to the document level property (Operation 350).
A user's authority for the second client 120 or the third client 130 is designated. The authority information for the second or third clients 120 and 130 can be designated by the user's authority. According to the user's authority, the second client 120 or the third client 130 can access the data in the directory designated according to the document level properties (Operation 360).
The embodiments of the present general inventive concept can be written as computer programs and can be implemented in general-use digital computers that execute the programs using a computer readable recording medium. Examples of the computer readable recording medium include magnetic storage media e.g., ROM, floppy disks, hard disks, etc., optical recording media e.g., CD-ROMs, or DVDs, and storage media such as carrier waves e.g., transmission through the Internet.
As described above, a document is transmitted to a specific folder of a document distribution system using a WebDAV protocol, so that a document distribution system can be configured without installing an additional file transmission protocol in a server. Also, various properties of data can be designated without modifying the data when transmitting the document.
Although a few embodiments of the present general inventive concept have been shown and described, it will be appreciated by those skilled in the art that changes may be made in these embodiments without departing from the principles and spirit of the general inventive concept, the scope of which is defined in the appended claims and their equivalents.
