[expertfinder-dev] Mappings between base vocabularies for ExpertFinder

[Axel Polleres]

Dear all,

I started to work on the mappings mentioned in our paper.
See

      http://www.rdfweb.org/topic/ExpertFinder_2fmappings

for details. Note that even for the supposedly simple case of mappings 
between vCard and FOAF, we need surprisingly expressive mappings way 
beyond OWL or RDFS subclass or subproperty definitions, but even beyond 
what is expressible in the current version of SPARQL by means of 
CONSTRUCT statements.

Opinions welcome, I think this exercise gives quite valuable insights.
When back from vacations, I plan to further work on these mappings, 
probably, I will provide some additional version in DLVHEX [1] rules, 
where some of the things we need can be expressed more elegantly in the 
future, but although being a very flexible framework for rules on top of 
RDF, DLVHEX cannot yet produce RDF as output. I expect to have this 
functionality in the future though, just "negotiating" with the developers.

cheers & merry christmas,
(you may view these first mappings as a "present", feel free to 
extend/comment over christmas!!! ;-) )

p.s.: I'll be off to christmas holidays tonite and back only january 
7th. probably without internet connection most of the time... Looks like 
a nice break, I think I won't miss it too much, the last few months were 
quite busy!
