I've added a much nicer looking screenshot of Topicalla, now with images and anti-aliased fonts. It shows a UI of a single FOAF file. The UI elements to use are determined from the data in the FOAF file. Some additional data is loaded from musicbrainz.org, although the loading part isn't handled automatically yet. One can select the Detail drop-down to show more detail such as the song titles on the albums, and the descriptions from the weblog.
I recently also added support for templates using XPath and XML datasources as well as the existing ReoPath and RDF support. It is generic enough now that support may be added for other kinds of datasources as well. This allows one to create a UI that is bound to some XML data. For instance, the following:
<hbox rp:repeaton="//td"> <label rp:assign="text()"/> </hbox>
