==Catalog Services for the Web (CSW) Core Queryables== The Open Geospatial Consortium Catalog Services for the Web (CSW) standard defines eleven "Core Queryables" that must be supported in any compliant implementation. Profiles of CSW map these queryables to concepts and xPaths for particular metadata dialects.

Theme KeywordA 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
