Summit 2008/Face. To. Face. Agenda – Next week (April 10, 2008): Developing an Ontology of Ontologies (for OOR): • http: //ontolog. cim 3. net/cgi-bin/wiki. pl? Conference. Call_2008_04_10 • Today: – – Focus is on potential content providers for such an OOR Rationale Expectations Requirements 2

Rationale • Why are we interested in an OOR and what purpose does it serve? • Isn’t the Semantic Web notion of distributed islands of semantics sufficient as a de facto repository? – If you put it out there, they will come? – If you build it better and put it out there, they will prefer yours? – History does not show this laissez faire “field of dreams” is good reality • So real rationale: – You can find it simply – It’s registered, so you know who built it – It’s got metadata, so you know the purpose, KR language, user group, etc. – It’s got metadata, so you know what the content subject area is – It’s got mappings, so you can connect it to other ontologies – It’s got quality and value, as gauged by recognized criteria – It’s got services, so that you can map and be mapped, can find and be found, can review/certify and be reviewed/certify, can hook your own services into and can use the services others have hooked in – It’s linked to multiple common middle and upper ontologies – It can be easily extended 3

Expectations • Will the OOR solve everything? • How will we stage our wants and needs? • Can we provide good service to end users, content providers, application developers? • In particular today, what do content providers expect to find and use? • What do content providers expect to be able to provide? 4

Requirements • • • What’s needed: today, tomorrow, next week? What do end users need? What do content providers need? What do application developers need? Architecture Ontology of Ontologies Quality and Gateway Criteria State of the Art OOR the reality: – Requirements -> Design -> Implementation -> Long-term Maintenance & Enhancement – A Technical Roadmap and Realization – How do we ensure long term value, quality, commitment, progress? • Towards the Ontology Summit 2008 Communique 5
