1 Ontology Application Management (OAM) Framework User Tutorial
Part 1: Database to Ontology Mapping & Semantic Search System Part 2: Recommender Application Management © LST Lab, NECTEC, Thailand Last updated: Aug 28, 2013

2 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.

3 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).
