It is important to understand that datalog is not a new query language. It is an old one, with a strong pedigree. It has power equivalent to the relational model plus recursion.

SPARQL is cool, and they did a good job making it look a little like datalog.

SPARQl1.0 is equivalent to a datalog without recursion. Wonder what SPARQL 1.1. with property paths is equivalent too. Any way a hobby project idea I won't have time for is implement the datomic api on top of a systap bigdata quad store.
