[Tracker] tracker RDF data

[Eyal Oren <eyal oren deri org>]

Hi,

I'm very interested in tracker. I saw it some months ago, and decided to 
check back now since it seems more mature and I really like it! 

I'm the developer of ActiveRDF [1], a Ruby library for easy access to 
various RDF datasources (somewhat similar to ActiveRecord or LINQ for SQL).  
I'm also working on a big European semantic desktop project called Nepomuk 
[2].  Nepomuk uses its own crawler and data extractor [4], but I would be 
very interested in using tracker instead.

It would be great if I could support tracker as an ActiveRDF datasource.  
Seeing that you use the W3C RDF query language [3], that could be quite 
easy. What would be best way to programmatically query the tracker 
database, I guess dbus? What do you return then? Is it possible for you to 
return RDF (in some serialisation such as ntriples [5])?

It would be great if we could use tracker as the crawled metadata in our 
semantic desktop.

[3] do you mean RDQL or SPARQL here, or something else?
