Semantic InteroperabilitySemantic Interoperability for geo-spatial data by using data definitions, terminologies, relations, gazetteers (Ontology ) etc.

supportNeed more

focus

○ Develop Ontology Registry.- Collect available ontology, taxonomy, terminology, gazetteer.- Provide ontology registry service such as visualization,

comparison.

○ Support development of a consistent ontology through registry of ontological information

- GEO participants can compare and analyze available ontology.- GEO participants can develop more interoperable and

appropriate ontology by referring to the registry.

Underlying idea of the proposed task

Ontology Registry Development-Ontology-Taxonomy , Terminology-Gazetteers

1.Registry service of available Ontology2.Defining/ Uncovering Semantic Relations3.Ontology Visualization /Editing Tools

Registration of ontology

Additional information on relationships of different ontology

Visualize available ontology

Help compare and analyzeexisting ontology

in developing new ones

Help develop consistent ontology in each domain though providing ontology/terminology registry service as a part of GCI
