How can I add my custom extensions to BuddySpace?
Probably the best way is to write your own plug-in (more information is / will be on http://kmi.open.ac.uk/projects/buddyspace/developers/). All plug-ins use common interface BSPlugin and are maintained by the BSPluginLoader. When implementing a new plug-in you may want to handle also some custom xml extensions. These are typically done by triple Tag, TagBuilder and TagHandler, which need to be registered in the Handler.properties file inside jabberbeans.jar. Best way to learn more is to look at the existing plug-ins.
