Update: December 7, 2007
Version 1.5: Implementation of new SPARQL spec (April 2006); improved query and loading performance of OWL Ontology Repository; removal of EODM Workbench (ontology editors); numerous bug fixes.
What is Integrated Ontology Development Toolkit (IODT)?
IODT is a toolkit for ontology-driven development. This toolkit includes EMF Ontolgy Definition Metamodel (EODM) and an OWL ontology repository named Scalable Ontology Repository (SOR).
EODM is derived from the OMG's Ontology Definition Metamodel (ODM) and implemented in Eclipse Modeling Framework (EMF). In order to facilitate software development and execution, EODM includes RDFS/OWL parsing and serialization, reasoning, and transformation between RDFS/OWL and other data-modeling languages. These functions can be invoked and called by the applications that use ontologies. EODM is also an Eclipse open-source project.
SOR is a high-performance OWL ontology storage, inference, and query system based on RDBMS (Relational Database Management Systems).
This technology runs on Windows® and Linux®.
How does it work?
IODT includes the following components, which can be downloaded and used independently or cooperatively:
- EODM is the run-time library that allows the application to read and serialize an RDFS/OWL ontology in RDF/XML format; manipulate an ontology using Java™ objects; call an inference engine and access inference results; and transform between ontology and other models.
- The OWL ontology repository, named Scalable Ontology Repository (SOR), is a high-performance OWL storage, inference, and query system based on RDBMS. It supports DLP (Description Logic Program), a subset of OWL DL, and the SPARQL language.
Version 1.5 contains the following enhancements:
- New SPARQL specification (April 2006) has been implememnted.
- Query and loading performance has been greatly improved by schema and index changes.
- EODM Workbench has been removed from this release. It is no longer supported. (Please download the 1.1.2 version if you want to try it).
- Numerous bugs have been fixed.
