OWLIM 4.3 Released
November 4, 2011
Ontotext are pleased to announce the release of OWLIM version 4.3
This release has been coordinated with the latest release of the Sesame openRDF framework
OWLIM 4.3 is bundled with Sesame 2.6 to deliver SPARQL 1.1 Federation. This emerging
SPARQL standard provides a means to distribute queries over multiple SPARQL
end-points. The big advantage of this technology is the ability to enrich query results
by 'joining' to other 3rd party resources, e.g. linked data services that provide a
SPARQL interface.
Many of the advanced features of OWLIM are implemented as plug-ins and the API for
building such extensions has been made public for this release. OWLIM plug-ins can
communicate and share data via various 'hooks' in to the processing pipelines. This
allows custom indices to be used, and opens up many possibilities for improving
performance and adding novel features.
OWLIM 4.4 is scheduled for release at the end of January 2012 and will include the much
anticipated data-type index for improved performance when dealing with range queries over
numeric and date/time types.
Full documentation for all OWLIM editions is available online.
