Re: ISSUE-66: Translation Scheme as proposed seems too complicated for the simple task of mapping <DB value(s), RDF term>

We have uploaded a new version (revision: 1.146) containing the same 
examples implemented using a new translation scheme that

    * is much simpler (does not use SKOS)
    * allows DB values to map to any RDF term (IRIs and literals)

The new scheme uses the following new R2RML terms:

    * rr:valueMap (range is class rr:ValueMap)
    * rr:value (range is xsd:string, really just plain literal)
    * rr:term (range is Term Map)

We have not patched the text around it yet. Also, we can further 
simplify the mapping via use of some syntactic sugar. We'll do these in 
a subsequent version.

Seema & Souri.
