Ok. Cool. Actually I had a conversation with Martyn on IRC few hours
ago. I am afraid I could not clearly put my question to him.

Just to avoid any misunderstanding, this not F-Spot. :-) I am planning
to use C++ to write this. :-)

So there will be an application(s) (like Conduit, maybe?) where the
user will be setting all the data sources (local directories, Flicrk
accounts, RSS feeds, etc.) she wants to be indexed and the miners will
fetch information from those sources and feed them into Tracker. Other
applications (like a photo manager) will just benefit from this by
querying Tracker. Am I right?

This seems like a relatively easy thing to do. I will give it a try
and let you know.

Happy hacking,
