  1. SOCoP Workshop 2010 Discussion Notes Frameworks, Vocabularies, Demos

  2. Vocabularies • E.g W3C Geo XG – formed GEO vocabularly and imagined 5 others. • VoCamp – feature-geometry, relationship, POI, events vocabularies sketched out • GeoSPARQL – feature-geometry, relationship vocabularies. • Next? Event? Sensor? Connectonomy(mereotopology)?,

  3. Methodology • Choose domain • Compose / steal in RDF • Lift into OWL? • Coordinates as WKT? • Stepping back – vocamp experience to build guidelines. • TAO of URI’s • Granularity? Does hierarchical naming help? Is there a danger in exploiting the URI structure? • Place no barriers to changing URI’s but never do it… • Decidability versus resonance…resonant cleanliness? • Minimalism -> tractability…microtheories

  4. Methodology, cont’d • Bottom-up alone has issues (consistency…) • Recommended upper or utility ontologies • Tools for vocabulary reuse • Overlap is good! Unless it’s confusing.

  5. Reference Model • Vocabulary standardization guidelines. • Value in “ontologizing” OGC concepts (UML, XML Schema, text)? • GeoSPARQL as focal point for priorities • Semantic mediation + linked data +? • ? Reasoning ? • Selection of layer – filter – symbolization – scale …

  6. Implementations • Cross-vocabulary visualization / exploration • Query expansion • GeoSPARQL implementation • (OGC policy – at least 2 implementations before specification approval) • Cross-vocabulary GeoSPARQL experience.

  7. Demonstrations • Query across multiple domain vocabularies • OWS-8 “Look-aside” versus “Pass-through” semantic queries. • Operation of vocabulary formation “process” • Essential queries (small-number-of)

  8. Actions • Merged concept for OWS-8, AIP-4, SOCoP demos. • Develop & maintain the vocabulary development best practices. • Prizes for creating the most same-as triples. • Use existing tools and USGS linked data to create and publish derivative services. • Publish page of existing tools available for use. • Leverage INTEROP and create educational resources.
