ANN: Thea OWL library for SWI Prolog v0.5

*Thea <http://www.semanticweb.gr/TheaOWLLib/>*

An OWL library for [SWI] Prolog



*Thea* is a Prolog library for generating and manipulating OWL 
<http://www.w3.org/2004/OWL/> (Web Ontology Language) content. *Thea* 
version 0.5 consists of:

    *

      OWL parser,

    *

      OWL generator and

    *

      SQL to OWL converter.

Current version of *Thea* OWL Prolog library (v 0.5) released April 21, 
2006.


Description

*Thea* OWL parser uses SWI-Prolog <http://www.swi-prolog.org/>'s 
Semantic Web library for parsing RDF/XML serialisations of OWL documents 
into RDF triples and then it builds a representation of the OWL ontology 
as it is defined in the OWL Web Ontology Language Semantics and Abstract 
Syntax <http://www.w3.org/TR/2004/REC-owl-semantics-20040210/> part of 
the OWL specification. The OWL ontology abstract syntax is implemented 
as Prolog terms. Thea has been tested extensively against the OWL test 
cases and for almost all cases it generates the correct syntactic 
constructs.

*Thea* OWL generator is used to the OWL absract sysntax constructs from 
Prolog terms into RDF triples and saving the resulting RDF model into an 
RDF/XML file. Thea OWL generator is also using SWI-Prolog 
<http://www.swi-prolog.org/>'s Semantic Web library for saving RDF 
models into RDF/XML files.

*Thea SQL to OWL converter* is used to generate OWL facts from records 
in a relational database. *SQL2OWL* uses SWI-Prolog's ODBC package to 
access the RDBMS. The conversion is guided by a mapping between 
Relational entities (Tables and Columns) and OWL constructs (Classes and 
Properties). The mapping is defined in a declarative form by means of 
Prolog terms.
