[Nepomuk] Queries not working as expected

[Alessandro Diaferia]

Hello list,
as already discussed with Vishesh some minutes ago there seems to be a
problem with the following SPARQL query:

"select ?url where { ?resource nie:url ?url . ?resource a nfo:Image . }"

This query returns less results than it should, skipping for example png
files.
In particular, as noticed by Vishesh, replacing nfo:Image with
nfo:RasterImage or nexif:Photo works fine.
Shouldn't nfo:Image cover all types of pictures?

My particular code is here: http://pastebin.com/TVj6HJGx

Also, is there a way to perform the same query using the API rather than
plain SPARQL?

Regards
