Who are we?

• Stanford Medical Informatics – part of the Stanford University School of Medicine

• Research project led by Mark Musen

• Comprise about a half-dozen full-time staff (2 programmers + researchers) + students

• Funded primarily by US Government grants and contracts (NCI, NLM)

• http://protege.stanford.edu

What have we done? (1)

• Built an free, open-source, extensible Java tool for developing and maintaining frame-based (OKBC) ontologies and knowledge-bases.

• Not built-in support for rules, inference, classification, etc.

• Acquired 6000 registered users, 1000 active users.

What have we* done? (2)

• A number our users have developed plug-ins including interfaces to rule-based systems, classification engines, etc (JESS, Prolog, FACT)

• Developed plug-ins for visualization, ontology management (merging, etc) and PSMs

• Built plug-ins to interface to XML Schema and RDFS

• Worked with SRI to develop a DAML+OIL plug-in (in alpha)

*and our users

What are our plans?

• We are (will be) funded by NCI to develop an OWL backend for Protégé.

• We have hired a postdoc who will be devoted to this effort.

• Our near-to-intermediate term goal is to provide good support for OWL-Lite, with eventual support for full OWL.

Why are we here?

• Create new disasters. (Find out how we can best work with the core OWL community to develop the best editing environment for OWL that we can.)

• Understand more about some of the technical problems in the spec

• Understand the plans/timeline for the spec• Better understand the OWL species• Encourage development of reference parser

What are our problems?

• “differentFrom”

• Need OWL full for:– Allowed-values– Metaclasses– Allowed-parents– Cardinality
