Background

The Open Geospatial Consortium (OGC) defines a OpenGIS® Catalogue Service Implementation Specification, including the ebRIM profile of CSW (ebRIM)

• OG Catalogue Services — ebRIM (ISO/TS 15000-3) profile of CSW

Instructions for adjusting this document for omar (and making it validate!) are available at OGCebRIM

Doing spatial Adhoc Query in Omar

We have to perform the following tasks

1. Load OGC CSW ebRIM catalog profile
2. WCSCapabilities to ebXML
3. Spatial index for gml:EnvelopeType slot types
4. Configure Adhoc Query
5. Perform Spatial Query

Mapping a Web Coverage Service Capabilities Document

(from the spec)

CSW <-> ebRim Mapping from [ebRIM profile of CSW]

CSW:Record	ebRim
dc:identifier	rim:RegistryObject/@id, rim:RegistryObject/rim:ExternalDriver/@Value
dc:type	rim:RegistryObject/@ObjectType
dc:title	rim:RegistryObject/@Name
dc:description	rim:RegistryObject/rim:Description
dc:subject	rim:RegistryObject/rim:Slot/rim:ValueList/rim:Value
dc:format	rim:ExtrinsicObject/@mimeType
ows:BoundingBox	rim:RegistryObject/rim:Slot
