About OAM Framework
• To simplify creation and adoption of a semantic web application.
– Provides common application templates that can process the user's published RDF data.
– User's programming skill is NOT REQUIRED in building a prototype application.
– Supports both RDF data publishing from databases and building ontology-based applications
• Semantic search, Recommender system applications.

Software used by and bundled with
OAM Framework user’s package
• Apache Jena ( http://jena.apache.org/ )
• D2RQ ( http://d2rq.org/ )
• Hozo ontology editor ( http://www.hozo.jp/ )
• Apache Tomcat ( http://tomcat.apache.org/ )
Note: OAM framework was originally developed as a companion application framework for OWL ontologies developed using Hozo ontology editor. It also works with OWL ontologies created using Protege 4.x Ontology Editor (although with some limitation).
