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 is currently compatible ONLY with OWL ontologies exported from Hozo ontology editor. We plan to add support for OWL ontologies created using other ontology editors, such as Protege ontology editor very soon.
