1. Japan and IEEE Ontology and Taxonomy Development for GEOSS as a part of AR-09-01: GEOSS Common Infrastructure (GCI)

2. Global Earth Observation System of Systems （ GEOSS ） What is “MODIS”? What is “ultra-sonic method” to measure air temperature?

3. DB DBDB 気象用語 biology term Landuse Classification schema Climatology Health Science Agriculture term Hydrology term 农业 เกษตรก รรม 농업 temp Air temperature Data cannot be accessed and used without knowing data name/definition a specification of a conceptualization: “Ontology” Should help find data. a specification of a conceptualization: “Ontology” Should help find data. Necessity of Ontology

4. Challenge for Data Interoperability Syntax Interoperability Proposal of Standard Schema and Interface. It is not always enough for diversified Geo-spatial Information. Need to Manage Very Large& Heterogeneous Data Very Large Image Data Data Stream from Sensor Networks Integrating Observation Data and Model Simulation Semantic Interoperability Semantic Interoperability for geo-spatial data by using data definitions, terminologies, relations, gazetteers (Ontology ) etc. support Need more focus

5. ○ 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

6. Ontology Development in each domain Human Health, Disaster, Weather, Climate Water Resource, Agriculture, Ecosystem, Oceans. Underlying idea of the proposed task Ontology Registry Development -Ontology -Taxonomy, Terminology -Gazetteers 1.Registry service of available Ontology 2.Defining/ Uncovering Semantic Relations 3.Ontology Visualization /Editing Tools Registration of ontology Additional information on relationships of different ontology Visualize available ontology Help compare and analyze existing ontology in developing new ones Help develop consistent ontology in each domain though providing ontology/terminology registry service as a part of GCI

8. Ontology Registry by Wiki Starting with the list of available ontology

9. Editing Tool “Semantic Media Wiki” allows tagging. http://semantic- mediawiki.org/wiki/Help:Introduction_to_Semantic _MediaWiki

10. Gazetteer ID Place name Latitude Longitude Language Country category Scale MBR Relation Life cycle Editing Date Collecting available gazetteers for comparison.
