Challenge for Data Interoperability Very Large Image Data Integrating Observation Data and Model Simulation Data Stream from Sensor Networks SyntaxInteroperability Proposal of Standard Schema and Interface. It is not always enough for diversified Geo-spatial Information. Need to Manage VeryLarge& Heterogeneous Data Need more focus support Semantic Interoperability Semantic Interoperability for geo-spatial data by using data definitions, terminologies, relations, gazetteers (Ontology ) etc.
○ 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. Proposal of New sub-Task
Underlying idea of the proposed task Ontology Development in each domain Human Health, Disaster, Weather , Climate Water Resource, Agriculture, Ecosystem, Oceans. Help develop consistent ontology in each domain though providing ontology/terminology registry service as a part of GCI Registration of ontology Additional information on relationships of different ontology Visualize available ontology Help compare and analyze existing ontology in developing new ones • Ontology Registry Development • Ontology • Taxonomy , Terminology • Gazetteers 1.Registry service of available Ontology 2.Defining/ Uncovering Semantic Relations 3.Ontology Visualization /Editing Tools

Editing Tool “Semantic Media Wiki” allows tagging. http://semantic-mediawiki.org/wiki/Help:Introduction_to_Semantic_MediaWiki
Gazetteer Collecting available gazetteers for comparison.
