We are very proud to announce the release of Sesame 2.4.0. This is a
major new release featuring support for SPARQL 1.1 Query.
Sesame 2.4.0 implements all features of SPARQL 1.1 Query as outlined in
the October 14 W3C Working Draft, with the exception of basic federated
query. SPARQL 1.1 for Sesame is developed by Ontotext in cooperation
with Aduna.
The list of new SPARQL query features includes:
- Use of expressions in the SELECT clause
- Aggregates (COUNT, MIN, MAX, AVG, SUM, GROUP_CONCAT), HAVING
and GROUP BY
- Property paths
- Subqueries
- Negation: (NOT) EXISTS and MINUS
- Set membership: (NOT) IN
- Conditionals: IF
- Various new builtin functions: COALESCE, BNODE, IRI,
isNumeric, strLang, strDt
Apart from this impressive array of new query language features, Sesame
2.4.0 also implements a number of bug fixes and improvements, including
scalability and performance improvement in the Native store. For a full
overview, see the release notes[1].
As always, the latest Sesame release and all relevant documentation can
