this is a list of links I gathered up which should cover the work I've done during the last month. I hope that I got everything ;)

also created during the development of the mapping and its tests:
- https://github.com/zazi/D2RQ-maven - a maven project of D2RQ that powers the LinkedBrainz D2R instance (incl. some patches that are included now in the main D2RQ project as well, see [12])

Yes, of course. However, I wasn't sure whether such mappings to existing ontology are really possible with R2RML, i.e., till now I thought that it wasn't implemented yet. However, I haven't checked these maps recently. Furthermore, are there any Semantic Web vendors which support R2RML right now?

We do :-)
I you look at R2R (released recently by Chris and Co.) you'll also see use of R2RML for mappings across RDF.

Cool! However, is this official yet? ;)

Yeah, I discovered these new features right now as well. However, it may still be a problem to transfer the logic that is implemented in the specific D2RQ Translator classes (see [1]) into SQL stored procedures or another (vendor-specific) technique, since R2RML doesn't support such a mechanism yet. Generally, I'm happy to get an R2RML mapping description out of the existing D2RQ mapping description. Unfortunately, the LinkedBrainz project ends in the end of July, i.e., there is no time left to do this as part of this project. Further contributions may only be based on a volunteer basis (as usual :\ ). Besides the MBZ NGS to MO etc. mapping is still not finished yet (see the end of this blog post [2], were I listed some open issues which I couldn't implement during my time on working on the LinkedBrainz project).

Not in a general release if that's what you mean. That's coming in September time.

just to let you know, I moved yesterday my LinkedBrainz projects to a separate location on GitHub [1], i.e. you will find [5,6,7,8,9,10,11,13] from below now at their new locations (see [5,6,7,8,9,10,11,13]).
