Hi I am pleased to announce the release 1.13 of EulerGUI, a development tool and a framework for the Semantic Web and rules, under LGPL license, in Java and Scala. There was no announcement here on Drools list since version 1.7.1 of EulerGUI in January 2011. As some of you know, EulerGUI is using Drools since beginning of 2009, as an engine for N3 logic (http://www.w3.org/2000/10/swap/doc/Rules) . N3 is a language for the Semantic Web equivalent to RDF, but much easier to read and write by hand. Moreover, N3 has an extension for rules, e.g. : { ?x parent ?y } => { ?y child ?x }. Such rules are translated in Drools language under the hood. This allows to make experts systems without writing any Java class for business domain. Moreover, it' possible to reuse the thousands of ontologies available in search engines. And there are also the hundreds of SPARQL data sources available in the Linked Open Data ( http://linkeddata.org/ ), notably http://dbpedia.org . The improvements since version 1.7.1 mainly concern : - N3 Drools inference engine: more builtins, embedded Java objects, - Semantic Web client GUI for SPARQL queries and update - local Jena TDB database (SPARQL) - generate a project skeleton ontology for missing declarations - new N3 sources : ATTEMPTO Controled English; Squall Controled English for SPARQL - download N3 sources from Internet in multithread, with cache - popup by which it is possible to kill an inference launch - in tools menu, add all referred Ontologies to current project - N3 command line interface ( BasicRuntime ) as a separate program - and many fixes The download is here: https://sourceforge.net/projects/eulergui/files/eulergui/1.13/ Full CHANGES list: https://eulergui.svn.sourceforge.net/svnroot/eulergui/trunk/eulergui/CHAN...
