[Nepomuk] File types

[Ivan Čukić]

Hi,

I've got a few questions regarding the files database.

The first one is whether it would be possible to add the file category 
(document, image, ...) to the sqlite mapping.

The second is an implementation detail.

The code uses prepared queries, and it prepares a query for every single call 
of the method which is sub-optimal. The preparation should be performed only 
once since the query does not change, just the argument.


Cheerio,
Ivan
