There are many resources being gathered for use as part of the project including:    (2RJO)

These will be increasingly made available based on input and collaboration.    (2RJV)

A start has been made on gathering ontologies and their storage as part of an open repository which was tested in late 2010. Relevant ontologies were selected as part of their domain relevance and potential for demonstrating added value to the scientific community (and society) by making existing geographic systems and applications interoperable and used within a semantic framework.    (2RJW)

Examples of ontologies in this base include the geonames ontology at http://www.geonames.org/ontology, ontologies published by the Ordnance Survey and Geo-Concepts http://www.geospatialmeaning.eu/geo-ontologies-survey/W3C-Geo2007/.    (2RKB)

As noted by the GEOSS (Global Earth System of Systems) effort several institutions have initiated efforts to propose a standard ontology and/or terminology/taxonomy related with Earth Observation. Besides GEOSS itself these include:    (2RJX)

The INSPIRE Registry "http://inspire-registry.jrc.ec.europa.eu/" http://inspire-registry.jrc.ec.europa.eu/) also constitute examples of structured vocabularies in the SDI domain.    (2RK8)

These are diverse approaches and question the community needs to address is how such multiple ‘vocabulariesÂ’ be shared across communities. One idea is to map them to specific domain ontologies which have suitable semantics for his and also an ontology that allows vocabularies to be objects that are maintained. This idea will be explored in early workshops such as the Geo-Vo-Camp-DC-2011 planned for June 3-4 (see http://vocamp.org/wiki/GeoVoCampDC2011#What).    (2RK9)
