Like Juan, I'm very interested in the similarities and the differences.

We're excited to work with you.

Oh cool, that could help meet the Candidate Recommendation exit
criteria. *And*, that would be fun to play with it :-)

I'm interested in your feedback there. Eric and I put the Scala
implementation in the spec as a direct translation of the mapping
function. You can find a proof-of-concept at [1].

We intend both RDB and RDF abstract models to be intuitive:
* the RDF model is directly the one from the spec [2]
* the relational model captures [3]
The algebra should be easily implementable in any language (trivial if
you have native sets and maps).

The main purpose of the Scala code today is to type-check our
definitions so we are sure we don't miss any case in the mapping.
