•	Title: Extending Enterprise Ontologies: Levels, Limits, and Tensions

Rationale
• The Ontolog Forum is an open, platform-neutral community, focused on issues associated with the engineering of business ontologies
• One of its main projects has been to develop a formal ontology based on the UBL schemas
• The community has used Protege in a number of ways. Some were successful. Some were not.

Who should attend?

• This workshop will report lessons learned, describe future projects, and other topics of general interest to the Protege community in general, as well as those interested in Ontological Engineering and eBusiness projects. This especially addresses those with expertise in the converstion of Protégé-based ontologies to OWL, RDF/S, XML/XSD, UML2, and related projects.
• Those with an interest in contributing to these general discussions of are encourage to attend and submit additional papers for consideration to Bob Smith (robsmith5@1talltrees.com) or Kurt Conrad (conrad@SagebrushGroup.com) on or before June 1st, 2004.

Scheduled Topics
• Management of Ontology Projects that Rely on Virtual, Volunteer Teams (Kurt Conrad)
• Extending Protege to Import and Export SUMO KIF (Pat Cassidy)
• Using Protege to Formalize the REA (Resources-Events-Agents) Ontology (Bill McCarthy)
• Development of Ontology-Based Meta-Standards to Integrate and Support the Development of Multiple, Normative Information Standards (Peter P. Yim)

Solicited Topics
• Collaborative infrastructures for distributed ontology development
• Tools for modeling and visualizing business ontologies
• Strategies for engaging and leveraging subject matter expertise
• Modeling business processes and associated knowledge flows
• Translating formalized models between representation standards and tools
• Elevating the semantic richness of implicit conceptual models
• Application of ontological engineering principles to the integration of existing database schemas
• Training people to contribute to an ontological engineering project
• Protege vs KIF: The Options and Tradeoffs

Notice: Due to space restrictions, we may need to limit the number of workshop attendees. Interested participants are invited to send us a statement of interest. If you want to give a presentation on one of the above topics, you should submit an extended abstract (around one or two pages), which will be published on the Workshop web site. Statement of interest for attendance and presentation submission should arrive before June 1st and should be sent Bob Smith at robsmith5@1talltrees.com or Kurt Conrad at conrad@SageBrushGroup.com
