yep, WSP server that translates protocol to tracker sparql queries is
working (with caveats )
The code would need some effort to get it in shape, as you might imagine
there has been quite a bit of bitrot especially of late as recent dce
rework broke it (although I have a WIP version working against current
master (even more hacky than usual)
I've also started to look at elastic search as a backend, and am going
to talk about that a little at sambaxp. Probably that talk would maybe
explain more (and in more detail) about some of these questions. I
intend to talk about state of the WSP work, revisit again and explain
how it works, what works, what doesn't, what is provided, talk a bit
about experience of experimenting with elasticsearch how that affect
what needs to be done with the current implementation etc. (or something
like that :-))
WSP is complex, generic and very windows centric, there is a large
impedance mismatch between the features that WSP seems to be able to
provide and query for and what say is available from tracker. (mileage
may vary with other indexers). The WSP support that I have worked on has
concentrated mainly on supporting the subset of queries that are emitted
when using the search UI ribbon in windows explorer. Additionally there
is a simple WSP samba search client that allows simple queries to
constructed to be targeted at any WSP server.
