  The present invention relates to a UML NOTE data distribution system and a UML NOTE data distribution method in which a server and a design terminal are connected through a network, and design support is performed when product design is performed using UML in a group.

  Conventionally, when a server and a design terminal are connected via a network and a group designs products using UML, each group modifies a previous design error or adopts a new technology at the development stage. Changes in the design content were announced to each group by, for example, each design engineer at a design meeting, or communicated to other groups affected by the design change by telephone or e-mail.

  If the number of related groups increases and the design becomes complicated, design work will not progress smoothly unless important information such as design changes is shared with the entire related group. Then, I missed it, forgot to communicate it to related groups, etc., and there was a problem that all the related engineers could not share information such as design changes reliably.

  The present invention has been made in view of the above-described conventional technical problems, and the comments written in the Note tag in the UML design data of the product under development at each design terminal are other than the above. It is an object of the present invention to provide a UML NOTE data distribution system and a UML NOTE data distribution method that can be reliably shared with users of design terminals.

Analysis means to read, Note list creation means for creating a Note list by registering the text of the Note tag read by the analysis means together with its writing date and time and terminal identification information, and the Note created by the Note list creation means Note list delivery means for delivering a list to each of the design terminals through the network.

  According to a fifth aspect of the present invention, in the server of the fourth aspect, the Note list creation means creates the Note list in XML.

  The invention of claim 6 is characterized in that, in the server of claim 5, the note list creation means creates the note list by RSS.

  In the UML NOTE data distribution method of the invention of claim 7, the server reads the text written in the Note tag in the UML design data sent from each design terminal through the network, and the server reads A process for creating a Note list by registering a note tag text together with its writing date and time and terminal identification information, a process for delivering the Note list to each of the design terminals through the network, and the design terminal Each has a process of displaying the Note list distributed from the server on a display device.

  The invention according to claim 8 is the UML NOTE data distribution method according to claim 7, wherein the note list is created in XML.

  The invention of claim 9 is the UML NOTE data distribution method of claim 8, wherein the note list is created by RSS.

  According to the present invention, the server distributes the comment written in the Note tag in the UML design data to each other UML design terminal at each UML design terminal, so that each UML design terminal uses another UML design at the browser. Multiple UML design terminals that can read comments in UML design data written in the terminal and connect design changes and other written information over the network even when products are developed in multiple groups Can be shared between.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 shows the configuration of a UML NOTE data distribution system according to an embodiment of the present invention. The UML NOTE data distribution system according to the present embodiment includes a server 1 and a plurality of design terminals 3 connected via a network 2 in order to share design data created using a UML editor. The server 1 performs the network communication unit 10 that performs network communication with other servers and the design terminal 3, and the text written in the Note (note) tag among the UML design data created by each design terminal 3. An analysis unit 11 to be read, a note list creation unit 12 that creates a note list by registering the text of the note tag read by the analysis unit 11 together with the writing date and terminal identification information in the list, and the note list creation unit 12 A note list distribution unit 13 that distributes the generated note list data to each design terminal 3 through the network 2 and a storage device 14 that stores various data and updates the data.

  The analysis unit 11 executes an XML analysis module such as Xerces (product name) for the analysis of the text written in the Note tag. In order to create the list data for each ID of the design terminal 3 in the order of update date, the Note list creation unit 12 uses, for example, SQL to write the text written in the Note tag of each design terminal 3 analyzed by the analysis unit 11. Execute the database module using. When the content of the Note list created by the Note list creation unit 12 has been updated since the previous delivery, the Note list delivery unit 13 displays the content of the updated part by changing the field row for each Note tag. The format XML is distributed to each design terminal 3. For this, for example, RSS (RDF Site Summary) software is used, and therefore the Note list to be created is XML.

  The network 2 is a LAN and is also connected to the Internet. Each of the design terminals 3 includes a network communication unit 30 for performing network communication, a UML editor 31 for creating UML design data, and an HTML browser 32 or RSS for displaying a Note list distributed from the server 1 on a display device. With a leader. The UML editor 31 is not particularly limited as long as it is a UML modeling software.

  Next, a UML NOTE data distribution method by the UML NOTE data distribution system having the above configuration will be described. On the server 1 side, each process of XML analysis by Servlet, extraction of a Note tag in UML design data, creation of a Note list, and delivery of the Note list by RSS is performed. FIG. 2 is a flowchart of this embodiment. For example, upload. When uploading a file of UML design data from each design terminal 3 using software such as cgi (step SQ11), the analysis unit 11 on the server 1 side checks whether the file is a UML file (step SQ12). If the file is not a UML file, the process ends as it is (step SQ20).

  If the upload file is a UML file in step SQ12, the analysis unit 11 starts analyzing the Note tag. In that case, first, for example, XML analysis is performed by software such as Xerces, the file contents are loaded while maintaining the nested state that is the feature of XML (step SQ13), the Note tag is recursively searched, and the Note list Is generated (step SQ14).

  The Note list creation unit 12 extracts the text that is the content of each Note tag recursively generated by the analysis unit 11, and generates the UML design terminal ID, the file name, and the text content as a Note list (step SQ15). ) And a Note list log to which a time stamp is further added (step SQ16).

  When receiving a log-in from a certain design terminal 3, the note list distribution unit 13 generates an access log of the user (design terminal 3) using RSS (step SQ17). Then, regarding the contents of the Note tag registered in the Note list between the previous access date and time of the design terminal 3 and the current access timing, the login user name, the Note tag file name, and the Note text are entered in the new Note list. And transmitted to the design terminal 3 that is the access source (steps S18 and SQ19).

  In the design terminal 3 at the access source, if this new arrival list is received from the server 1 through the network 2, the new arrival list is displayed on the display device by the HTML browser or the RSS reader, and there has been any design change in any design group. Can be confirmed by looking at the contents of the new Note list.

  FIG. 3 shows an example of a UML design screen in the UML editor on the design terminal 3 side. A comment (text) using Note 35 can be written in any of 9 types of UML diagrams. With this, the part changed by each design group during the design is written in the Note, the server 2 is accessed by uploading the update, the server 2 side analyzes it, and the writing to the Note is made into the Note list. Can be held. Transmission of UML design data through the network 2 is performed on an XML basis. An example of the format is shown in FIG.

  FIG. 5 is a display screen of a new arrival note list distributed from the server 1 to the design terminal 3. Thereby, the design terminal 3 can grasp the development progress status of each group of products developed in the group and can know the design change.
