Not yet. I'm planning an overhaul of email analyzer. I'd really like to see 
his discussed and finally decided on first. Maybe NMO proposal is a good 
candidate for ticket-a-day :)

This pre-release is intended to compile a list of issues to be fixed. If you 
find any other, please let me know.

We're sort of forced to rush 7.0 out of the door, because we really have to 
break stuff^H^H^H^H change ontology before kde 4.3 is out. After this, minor 
releases aren't going to be a problem. This doesn't mean I consider 7.0 to be 
very broken. But I guess it still has some rough edges.

Deb guys will break it up. Actually it's already separated AFAIK. not sure 
about other binary distros. Might give them a hint.

For Gentoo it's going to be a sort of a problem. Gentoo guys usually prefer 
one package per one released tar.gz with a set of use flags to compile library, 
daemon, support for various deps etc. So it means than in gentoo tracker 
ebuild would depend on strigi ebuild. Alternatively if you can build 
libstreamanalyzer separately they might introduce two conflicting ebuilds for 
strigi and libstreamanalyzer with tracker ebuild being able to use either of 

Which approach is taken depends on tracker guys being willing to be bashed by 
anti-kde trolls :)

I'm putting it on my todo list to ensure that there's an option to build 
libstreamanalyzer separately

P.S. just checked and it seems that if I run regular build commands in 
streamanalyzer dir, everything builds properly and is installed.

P.P.S. One more unresolved issue: libstreamanalyzer currently drags ontologies 
along. We might want to fix this to use shared ontologies, or rather fix it to 
not care about ontologies at all. The question is: should libstreamanalyzer 
try and validate analyzer output(especially 3rd-party analyzer output) against 
the ontology or should it be done at backend level?
