Description

Allows users logged into a client-server version of Protege to chat in real time. Aims to provide the same sort of functionality as Yahoo! Messenger or Google Talk. The HTML Chat tab supports HTML-style editing (Bold, Italics, Underline, Strikethrough) along with dynamic hyperlink detections and internal link detections (more on internal links below).

Example

Consider the newspaper example which is included by default with Protege. Remember that you need to be running in client-server mode to use the HTML Chat tab.

1. Get the Chat tab by enabling it from the Project | Configure... menu item.

2. As you type, the Chat tab automatically detects any hyperlinks that you enter and enables them. Clicking the link opens it in a separate browser.

3. If you want to add an internal link pointing to a Protege class (e.g., Library) in the project, just type @'Library' as shown in the screenshot below. Notice that the link becomes enabled. In other words, to create internal link to "XXX XXX" we need to type @'XXX XXX'.

4. When you click on the internal link, the class form for the Library class opens. The internal link functionality works for classes, slots, and instances in the project. The Chat tab also supports text formatting as shown in the screenshot above.

PLEASE NOTE

Internal links: If the size of your knowledge base is huge (i.e., it contains many classes, instances, and slots), then searching is more efficient if done using the "internal name" of the class, slot, or instance instead of the "display name". This consideration becomes important for instances because their "internal name" often differs from the "display name". Most instances have system generated names like "newspaper_instance_10000", etc. The "display name" could be something as simple as "Ms Gardiner". The threshold (maximum number of frames allowed to be searched by "display name") can be specified in the properties file by changing value of "editor.pane.browsertext.frame.limit". The default value is set to 10000. This means that if the total number of classes, slots, and instances in the knowledge base exceeds 10000, then the search for internal links would be done by the "internal name" and not by the "display name".

Installation

The HMTL Chat tab is bundled with the "full" installation of Protege (version 3.4 beta, build 110 and higher). The source code for is available from the Protege Subversion repository:
