[Eulergui-user] EulerGUI 2.0 released

[Jean-Marc V. <jea...@gm...>]

It's not perfect, but it's time to turn the page! Towards new Turtle
project format, 100% Scala code, modularization, and quicker startup .


The accent in this release is the new N3 file format for projects, that is
OWL (and Protégé) compatible. Here is an example:

@prefix : <http://eulergui.sf.net/ontology/project.owl.n3#>.
@prefix owl:  <http://www.w3.org/2002/07/owl#> .
@prefix rdfs: <http://www.w3.org/2000/01/rdf-schema#> .

<> a owl:Ontology.

<> owl:imports <plants.n3> .
               <plants.n3> :isActivated false . # true by default

# the main N3 query
<> :hasN3Query <plants-q.n3> .
               <plants-q.n3> :isMainQuery true .

# Import of an RDF or OWL document
<> owl:imports <herbivores.owl> .

<> :subproject <subproject.n3p.n3> . # recommanded suffix .n3p.n3
<> :postProcessing <project-post.n3p.n3> . # only one postProcessing

There is a migration batch program ProjectFormatMigration.scala.


Otherwise , the raw change log is here:

GUI

   - new N3 file format for projects OWL compatible

   with migration batch program ProjectFormatMigration.scala
   - in GUI or from command line, add N3 from abbreviated URL: well known
   prefixes are recognized,

   e.g. dbpedia:Jimi_Hendrix , foaf: , sioc: , sioc:Role

   ( uses prefix.cc web service )
   - try RDFa and microdata on an HTTP URL (and add resulting N3 to
   project) :

   implementation uses web service http://www.w3.org/2012/pyRdfa/
   extract?uri=url
   - migrate from Pellet to OWL API and Hermit for OWL tree view

Rule engines

   - CLIPS Inference Engine ( and N3 rule base for translating N3 to CLIPS )
   - Drools/N3 engine :

   * use Euler Argument --pass to output the deductive closure, like Euler
   does

   * now Euler builtin e:trace does not break Drools / N3 engine

Framework

   - library updates : scala 2.10.3 ; Euler 2013-11 ; Drools 5.5.0.Final,
   OWL API 3.4.4, Jena latest ( 2.11.0 ), Hermit 1.3.8.2, JLine 2.11
   - Jena TDB cache is implemented in class RuleBasedApplicationWithCache.

   It uses both triples store in memory (Drools backed rule engine), and
   persistent TDB store.
   - new programs and API (linked to each other):

   * N3FormApp, generates a form from an ontology : show Datatype Input
   error as tooltip; the incorrect field are red like in N3 Table

   * SWExplorer, Semantic Web Explorer displays contents of an URI as a
   form view, and navigates by hyperlinks, uses new Jena TDB cache,

       combobox for WikiPdepia disambiguation, opening matching dbpedia URI
   (using JSON Web API)

   * DataGUI extends SWExplorer: allows to enter context based triples
   while navigating the semantic web

   * SWMonitorGUI triple store (SPARQL) monitor: shows simplified N3
   queries and named graphs

FIX

   - rule with e:findall containing N3 "a" abbreviation
   - post-Processing with EYE Euler
   - Now Euler / Eye can be stopped by clicking "Cancel"
   - avoid troubles at EulerGUI startup when a broken graphviz is installed
   (report by dmiles_afk on Windows)
   - typo on prefix dbprop
