FIG. 5 is a system-level sequence diagram for explaining the flow of a mechanism for developing an article updated on the Internet during map browsing on a map in real time.
First, a request is transmitted from the location content browsing terminal to the map information providing server 600. (Step ST10)

  The request for map information (step ST10) preferably uses a standardized service interface such as WMS (Web Map Service). Further, it is preferable that the map information providing server 600 also provides a service corresponding to WMS.

  Based on the content of the request, the map information providing server 600 searches for map information (step ST11). A response of the map search result is returned to the position content browsing terminal 300 (step ST12). The map received by the location content browsing terminal 300 is displayed (step ST13).

  The display of the map in the position content browsing terminal 300 is preferably arranged on the screen based on the real coordinate information, and the position content can be displayed in a hierarchy on the map.

  Moreover, it is preferable that the position content browsing terminal 300 can acquire only the position content asynchronously with the Web page.

  A request is transmitted from the location content browsing terminal 300 to the location content collection server 100 (step ST14). The request is processed in the request processing unit 11 of the location content collection server 100, and the search processing unit 16 searches the location content database 10 for location content (step ST15). A response of the search result is returned to the position content browsing terminal (step ST16). The position content is displayed on the upper display hierarchy of the map received by the position content browsing terminal 300 (step ST17). After receiving the current map information and location content, the location content is requested again from the location content collection server 100 in order to continuously receive the location information of the latest information (step ST18). After being received by the request unit processing unit 11 of the location content collection server 100, the processing is temporarily suspended in the request queue of the request control unit 12. While waiting for delivery until receiving a location content update notification from the location content transmission server (step ST19), the location content browsing terminal 300 enters a response standby state.

  Requests held in the request queue are preferably managed by the same thread.

  Article posting of local content is performed from the local content providing terminals 400 and 500 to the local content transmission server 200 (step ST20). The registration processing unit 21 of the local content transmission server 200 performs registration processing on the local content database 20 (step ST21). The update notification unit 22 sends an update notification to the location content collection server 100.

  Since the update notification method is as described in [0028], it is omitted.

  Upon receiving the update notification, the location content collection server 100 requests content information from the local content transmission server 200 based on the URI described in the message body of the update notification (step ST22). The local content transmission server 200 returns the HTML content of the Web site that has received the request (step ST23). Since the meta information related to the position cannot be recognized from the Web content specified in the acquired URI, the URI of the RDF site summary described in the header part of the WEB content is acquired (step ST25), and the local content transmission server 200 is obtained. Then, a request for the RDF site summary of the target site is made (step ST26). The local content transmission server 200 returns the RDF site summary content of the requested Web site (step ST27). In the position information processing unit 14 of the position content collection server, coordinates such as extracting position coordinates from the coordinate character string or coordinate binary data from the contents described in the RDF site summary contents, or converting the address character string to position coordinates, etc. Information is acquired (step ST28). Release notification is performed for a request waiting in the request queue (step ST29). As the request is released, the process is retried (step ST30).

  In [0038], it is preferable to release the thread and continue the processing with a new thread for the request whose hold has been released.

  Search processing is performed from the search processing unit 16 to the location content database 10 (step ST31).

  Based on the search process, position information encoded by the distribution processing unit 17 is generated and distributed to the position content browsing terminal 300 (step ST32).

  The latest location content is received at the location content browsing terminal 300, and redisplayed on the upper display hierarchy of the map based on the described coordinates (step ST33).
