Nepomuk in 4.13 and beyond

I'm not sure this was *the* problem with nepomuk adoption, but lets ignore 
that for a moment :)

So, nepomuk was based on rdf and sparql. Essentially, a simple and 
standardized yet really slow (and overly academic) technology that (in our 
case) introduced quite a few issues, as you already stated.

What is a replacement for sparql in baloo? (the wiki page is quite 
underwhelming)

Things here seem to be quite separated. Are the different 'stores' at least 
sharing a same instance of a database? (aka, are akonadi, and other stores 
going to share a single instance of **sql)

How are the following things going to be implemented (some use-cases that come 
to mind):
 - telepathy and akonadi contacts (kpeople implementation)
 - linking a contact (kpeople vs akonadi) to an activity
 - linking a file to an activity
 - linking an application to an activity
 - getting emails of contacts that are linked to an activity
 - getting emails with attachments of contacts that are linked to an activity

Agreed. RDF stores are usually slow because they focus on flexibility as a 
most common use-case which it is not.

> you've read the basic ideas behind Baloo [2]

As I said, the basic ideas are overly basic when you come from outside world 
and don't know what is written between the lines. :)

Ch!
