SOCoP Workshop 2010

Discussion Notes

Frameworks, Vocabularies, Demos


Vocabularies

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)?,


Methodology

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


Methodology cont d

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.


Reference model

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 …


Implementations

Implementations

  • Cross-vocabulary visualization / exploration

  • Query expansion

  • GeoSPARQL implementation

  • (OGC policy – at least 2 implementations before specification approval)

  • Cross-vocabulary GeoSPARQL experience.


Demonstrations

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)


Actions

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.
