  1. Open Ontology Repository Initiative Mike Dean mdean@bbn.com SOCoP Workshop MITRE McLean 17 October 2008

  2. Open Ontology Repository • Recent effort to promote use of ontologies by extending and federating ontology repositories • Convened by Leo Obrst, Peter Yim, and Mike Dean last October • Incubated by the Ontolog Forum (a virtual community of practice) • Central topic for Ontology Summit 2008 (third annual event co-organized by NIST, NCOR, and OntoLog) • ~3 months of online discussions and virtual panel sessions culminating in a 2-day face-to-face workshop at NIST • ~70 participants (government, academia, industry) • Requirements, issues, and ideas documented in the Ontology Summit 2008 Communique • Full details at http://openontologyrepository.org

  3. Existing Ontology Repositories • DAML Ontology Library • SchemaWeb • Ontaria • Protégé Ontology Library • Extended MetaData Registry (XMDR) • OBO Foundry • CODS • BioPortal • OntoSelect • TONES Ontology Repository • …

  4. OOR Key Features • Registry (metadata search) and repository (storage) • Multiple languages (OWL, Common Logic, etc.) • Gatekeeping and quality control • Full lifecycle support • Mappings/alignment between ontologies • Federation among multiple repositories

  5. Proposed Roadmap • 1 public site + public/private instantiations • Emphasis on federation, including loose ontologies and collaborative editing sites • Apache Server-like modular software architecture • Sites select languages, metadata, repository, IPR and other policies, governance, etc. they want to support • Initial support for OWL and Common Logic • Leverage and “cross reference” related efforts while seeking dedicated funding • More details in slides 55-64 of Ontology Summit 2008 OOR Team Presentation

  6. 3 Initial Threads • Continued implementation of Roadmap • Refinement of interfaces • Encapsulate existing components, e.g. from BioPortal, XMDR, etc. • Develop federation interfaces to other repositories • Volunteer effort • Pairwise integration of BioPortal (including LexGrid) and XMDR as an initial capability • Leverages existing funded projects • Pursue OOR-specific funding • All lead to public instantiation on openontologyrepository.net (infrastructure provided by CIM3)

  7. OOR Project • OOR has a public software developmentproject on the SemWebCentral.org GForge site • http://projects.semwebcentral.org/projects/oor/ • Anyone can download • Interested developers can register for an account using New Account and send email to mdean@bbn.com to be added

  8. Module Hierarchy • Standard composable interfaces and (currently) stubbed example implementations • Each site selects which modules they want to support • Each module supports its own configuration options • Developers can “vote with their code” • Code available at http://oor.projects.semwebcentral.org/

  9. NCBO BioPortal • 2.0 released in August • Led by developers of Protégé at Stanford • Supports OWL and OBO ontologies, LexGrid structured vocabularies, and mappings • Generic technology, not specific to bioinformatics • Modular, service-based architecture • Single portal (no federation) • Ongoing NIH project • http://bioportal.bioontology.org

  10. SOCoP Applicability • SOCoP brings together multiple communities each with their own ontologies and other data models • Desire to manage, evolve, and map these ontologies • An ontology repository was a key component of last year’s INTEROP proposal by SOCoP members • Separate from repositories of instances • OGC Catalogue Service • OOR has less, if any, need for geospatial indexing, etc.

  11. More Information • openontologyrepository.org • Telecons every other Friday • Representatives of ~10 organizations actively participating – we’d welcome more • Implementation rather than discussion focus • Podcast recordings available • Frank Olken’s OOR briefing at http://ontolog.cim3.net/forum/oor-forum/2008-09/msg00006.html • Provides more detail on Communique topics
