Thanks for this insight. 
The SPARQL approach indeed is much more generic and accomodates more easily
SKOS extensions

I did miss out on the SPARQL 2 extensions and in particular the full text
search is a particular feature I would be needing for retrieving concepts by

Let me turn the question around, if you don't mind.

Since we began the SKOS work in the SWAD-Europe project 5 years ago, a 
lot has happened. We now have a standardised RDF query language (SPARQL) 
including a Web (HTTP/REST) protocol and supporting formats (XML, JSON).

W3C also has recently renewed work on SPARQL. See the SPARQL Working 
Group wiki page here - http://www.w3.org/2009/sparql/wiki/Main_Page
Charter - http://www.w3.org/2009/01/sparql-charter
Proposed features - http://www.w3.org/2009/sparql/wiki/Category:Features

- Is there anything in the old SKOS API that you couldn't do in SPARQL?

- Is there anything *useful* in the old SKOS API that you couldn't do in 

- Is there anything useful in the old SKOS API that could fit into the 
proposed features for SPARQL 2.0?

- Is there any implementation experience about updating SKOS API-based 
systems to use SKOS "2009" which should be written down in the wiki 
http://esw.w3.org/topic/SkosDev ?

- Would publishing that advice as a snapshotted W3C Note instead make 
any practical difference? (eg. a precise reference is needed for 
government agencies commissioning software?)

Thanks for any detail,
