Re: [JavaScriptFunctions] any WG implementations / advocacy?

Why just Javascript? I have the impression that most SPARQL 
implementations are written in some other language, and this would force 
the implementation to include a JS engine. But, if not JS, then what? A 
language independent declarative description of a functionality?

I think it is cool but way beyond what SPARQL1.1 could handle. Maybe 
SPARQL 2? :-)
