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 DAMLOIL plug-in (in
  alpha)and our users

5
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.

6
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

7
What are our problems?

• differentFrom
• Need OWL full for
• Allowed-values
• Metaclasses
• Allowed-parents
• Cardinality
