Spatial Ontology Community of
Practice (SOCoP)
• SOCoP was developed because of the:
– Recognition of the semantic interoperability
component of geospatial data
– Realization of the potential of ontologies and
formal representations to help solve semantic
heterogeneity in geospatial data
•
SOCoP officially began in Oct. 2006
after a June meeting at the National
Science Foundation

SOCoP (www.socop.org)
• Membership in SOCoP is open to anyone
• Conference calls are held every month,
currently on the 3rd Wednesday
at 11:00 Eastern time
• Through an NSF INTEROP grant, we are
expanding SOCoP to create a larger Network
• We invite those here to participate.

INTEROP – Spatial Ontology Community of
Practice: an Interdisciplinary Network to
Support Geospatial Data Sharing,
Integration, and Interoperability
NSF Program: Community-based Data
Interoperability Networks (INTEROP)

Purpose of the SOCoP INTEROP Grant
• Apply and develop semantic technologies for the
Geospatial domain
• Share ontologies to promote data interoperability

• We have started to create pages
here, including educational
material

Original Semantic Web Vision:
Mark up Web documents and data
to be machine-processable
This requires:
Spatial representation
•Additional Knowledge Representation
(HTML  XML, RDF, OWL)
Spatial ontologies
•Ontologies
•Reasoners
Spatial reasoners,
Spatial rules,
Spatial operators

A Vision for Spatial Semantics and
Ontologies
• Improve search for geospatial data and services
– Ontologies for semantics and background knowledge
• Improve querying in geospatial data
– Semantic interoperability
• Combining information, Discovering new information
• Role of ontologies in different geo-architectures
– e.g., demos, decision-support systems,
cyberinfrastructures
• Geospatial data in the Linked Open Data cloud

Putting
Wisconsin
data into
RDF and
(maybe)
eventually
into the
LOD cloud
D2RMap (.dbf -> RDF)
Sesame (store)
Possible Workshop
• Design to incorporate semantics/ontologies
into computer architectures
– Spatial Data Infrastructures, portals,
cyberinfrastructures, information systems
• Where/how do ontologies fit in?
– How are they found? Remote ontologies? What
component knows which ontology to use? Use
of DBMS? Ontology driver for entire system?
