Update on Open Geospatial Ontology Repositories Mike Dean mdean@bbn. com 2 nd Annual SOCo. P Workshop MITRE Mc. Lean 12 November 2009 1

Open Ontology Repository (OOR) • Collaborative effort started in December 2007 – Subject of Ontology Summit 2008 – Incubated by Ontolog • Open source software to support sharing of open source and other ontologies • Current implementation based on Bio. Portal – Domain independent, despite the name – “Sandbox” implementation in place, preparing for production deployment • See http: //openontologyrepository. org 2

Desired Characteristics • Multiple language support (OWL, Common Logic, …) • Ontology mapping capabilities • Gatekeeping policies (curated, ratings, etc. ) • Metadata and provenance • Federation with OOR and other repositories and tools (bi- or uni-directional) • Modular software architecture that allows OOR instances to select their features and policies • … 3

SOCo. P Repository Efforts • An NSF proposal submitted by SOCo. P members emphasized development of an ontology registry/repository to facilitate ontology awareness and reuse • A recent resubmission proposed use and extension of OOR as the repository – OOR’s bootstrap funding strategy is to align with others proposals with common goals 4

Demo • OOR sandbox http: //oor-01. cim 3. net • Pre-loaded with several geospatial ontologies – Basic RDF Geo Vocabulary (wgs 84_pos) – GEO 2007 (from W 3 C Geospatial XG) – Spatial Relations (from Neo. Geo. Vo. Camp) • Capabilities – Browsing – Searching – Alignment 5

OOR 6

Larger Scale Example • Bio. Portal http: //bioportal. bioontology. org/ 7

Questions • What additional capabilities are needed in a repository for geospatial ontologies? (not generally including instances) – Spatial/temporal indexing? – Coordinate reference systems? – Federation with geospatial web services? • Would you be interested in using and/or helping to develop such a repository? 8
