Ellos incluyen conceptos, generalmente encerrados en círculos o cajitas de algún tipo, y relaciones entre los conceptos indicadas por una línea conectiva que enlaza dos conceptos. Introducción Los mapas conceptuales son herramientas gráficas para organizar y representar conocimiento. 'Public Cmaps', 'Science Cmaps', and 'History Cmaps' were located via the Directory of. 'Corporate Cmaps' is located as a Private Place by explicitly providing the Internet address of the CmapServer. The 'Students Cmaps' Place is located via broadcast since the user's computer is on the same LAN as that CmapServer. Figure 6 shows a CmapTools client connected to a variety of Places through the three mechanisms described above. The client program will locate the server by various means and will know that it corresponds to the same Place. A server on the same LAN as the client, or one that is registered with the Directory of Places can be added as a Private Place in a client. A Private Place does not have to be behind a firewall or inaccessible via broadcast or through the Directory of Places.

Additionally, both of these users could be working on Places located via the Directory of Places described above. The one on the left is accessing the 'Students Cmaps' Place via broadcast, while the user on the right is also accessing the 'Corporate Cmaps' Place that was located by explicitly giving its Internet address. The same dialogue box can be used to remove or edit a Private Place from the list of servers to be contacted.

Once the address of a Private Place is provided, the client will attempt to locate that Place every time it is executed. We refer to Places that are located via the explicit Internet address provided by the user as Private Places. In addition to the IP address, the user must provide the 'Port' on which the server is listening. If the client CmapTools program is not on the same LAN as the server, then the user must explicitly provide the Internet address (IP or domain address) of the server in the program's Preferences dialogue box (Edit/Preferences menu item in CmapTools).

CmapServers may be configured not to register with a Directory of Places, or may be behind a firewall that prevents the registration from taking place.

Figure 4 shows a CmapTools client obtaining the servers information from the Directory of Places and accessing the various servers. Recently installed CmapServers will be located and show up in the CmapTools client. It then proceeds to contact each of those servers to make sure it is accessible and retrieve information about the Place. When the client CmapTools program starts executing, it contacts the Directory of Places defined in its configuration and retrieves the list of CmapServers that are available. If a Directory of Places does not receive a heartbeat from a CmapServer for a period of time, it removes it from its list of active servers.

Periodically, the CmapServer contacts the Directory of Places providing a 'heartbeat' -an indication that it is still up and running. In addition to its Internet address, the CmapServer provides other pertinent data, such as its name (Place) and other identifying information, and the services it is running (services include Discussion Threads, Knowledge Soups, Synchronous Collaboration, etc.). When a CmapServer starts running it contacts the Directory of Places it has defined in its configuration or the Directory of Places that might be running on the same local area network and it has located through broadcast. Directory of Places is a special type of server that handles 'registrations' from CmapServers.
