Data Discovery (CSW)

Catalogue Services for the Web (CSW) is an Open Geospatial Consortium (OGC) standard designed to support interfaces that discover, browse, and query metadata about data, services, and other related resources. CSW defines Core Queryables, Core Returnables, and Other Queryables that cab be supported in any compliant implementation. Profiles of CSW map these fields to concepts and xPaths for particular metadata dialects.

Catalog Services for the Web (CSW) Core Queryables

The Open Geospatial Consortium Catalog Services for the Web (CSW) standard defines 11 Core Queryables that must be supported in any compliant implementation. Profiles of CSW map these queryables to concepts and xPaths for particular metadata dialects. For additional reference information see the ISO Profile of CSW (Table 6).

Concept	Description	Dialect (Fit) Paths
Theme Keyword	A word or phrase that describes some aspect of a resource. Can be one of several types. Note: The general identification keywords usually have a type of "theme" and are refered to as "theme keywords". Other types and vocabularies are used for other information. Service Entry Resource Format (SERF) requires a Science and a Service GCMD Keyword. This concept is called Subject in the CSW Specification.

Catalog Services for the Web (CSW) Core Returnable Properties

The Open Geospatial Consortium Catalog Services for the Web (CSW) standard defines 15 Core Returnables that must be supported in any compliant implementation. Profiles of CSW map these queryables to concepts and xPaths for particular metadata dialects. For additional reference information see the ISO Profile of CSW (Table 9).

xPath Note: The xPaths included in these tables use several wildcards. // means any path, so //gmd:CI_ResponsibleParty indicates a gmd:CI_ResponsibleParty anywhere in an XML file. /*/ indicates a single level with several possible elements. This usually indicates one of several concrete realizations of an abstract object. For example /*/gmd:identificationInfo could be gmd:MD_Metadata/gmd:identificationInfo or gmi:MI_Metadata/gmd:identificationInfo and gmd:identificationInfo//*/gmd:descriptiveKeywords could be gmd:identificationInfo/gmd:MD_DataIdentification/gmd:descriptiveKeywords or gmd:identificationInfo/srv:SV_ServiceIdentification/gmd:descriptiveKeywords. Fit: The fit of the dialect path with the concept is estimated on a scale of 1 = excellent two-way fit, 2 = one-way fit or some other problem, 3 - extension required.
