I just released version 1.1.0 of the Ruby SPARQL gem [1]. This is a fairly
completely functional implementation of SPARQL 1.1 Query. The notable exception
is for Property Paths, which are not supported yet. I intend to get there too,
but this is a significantly more difficult thing to implement, so that would be
delayed until a subsequent release, along with SPARQL Update, Federated
Queries, Entailment regimes and the Graph Store protocol.
In particular, the following new features are added from SPARQL 1.1:
• Functions
• BIND
• GROUP BY
• Aggregates
• Subqueries
• Inline Data
• Exists
• Negation
The SPARQL gem is in the public-domain, and cloneable on GitHub [2].
