You can create and maintain semantic models (often referred to as "ontologies") written in the ObjectLogic, RDF and OWL languages. Due to a harmonization of ObjectLogic, OWL and RDF to help make OntoStudio more user friendly, OntoStudio now provides one single perspective for all three ontology languages. The modeling perspective is the only and the easiest way to modify your ontologies. Its simple and user friendly interface is mostly self-explanatory. For more information about supported RDF and OWL features see the README.TXT file.

An ontology defines a common vocabulary for researchers and experts who need to share information in a domain. It includes machine-interpretable definitions of basic classes in the domain and relations between them.

Why would someone want to develop an ontology?

To share common understanding of the structure of information among people.
To enable the reuse of the domain and expert knowledge.
To make the domain assumptions explicit.
To separate the domain and expert knowledge from the operational knowledge.
To analyze the domain and expert knowledge.

Furthermore, you must answer the following questions when developing an ontology:

Which domain will the ontology cover?
What is the purpose of the ontology?
To what types of questions should the information in the ontology provide answers?
Who will use and maintain the ontology?


An ObjectLogic Tutorial is available in the OntoStudio help system.
