[DL] [ANN] -ontop- v.1.18

[Guohui Xiao]

We are happy to announce the availability of

           -ontop- v1.18

a Java framework to query ontologies with mappings to databases.

If you are interested in virtual RDF graphs, R2RML mappings and/or
RDFS/OWL2QL reasoning, then -ontop- is for you. The system implements
the cutting edge SPARQL-to-SQL and query optimisation techniques that
allow it to answer SPARQL queries using SQL databases while obtaining
great performance.

With -ontop-, you don't need to move your data from your already
efficient database in order to enjoy the benefits of the RDF data
model, the SPARQL query language or RDF/OWL2QL inference.
And there is no need for expensive ETL or forward/backward chaining either.

You can use -ontop- from command line, as a Java API, as a SPARQL
end-point, or as a Protege plugin.

After the deployment to -ontop- v1.17 to Protege plugin repository, we have
received many feedback and bug reports,
most of which are addressed in this new release.

The highlights of this new release include:

- Improvement of Protege plugin
-- Redesigned materialization action dialog
-- Upgrade to Protege 5.0.0 (latest version)
-- Numerous bug fixes

- Support of SPARQL querying of annotation property assertions in the
ontology
- Support of the use of owl:sameAs in mappings
- Upgrade OWLAPI to v4.2.5

The system is available for FREE at

If you are a protege user, you will receive the new version of -ontop-
plugin automatically.

Please, try it out and help us improve it by sending us your feedback.

Tell us how YOU are using -ontop-!
