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.
