KeywordA word or phrase that describes some aspect of a resource. Can be one of several types.

Service Entry Resource Format (SERF) requires a Science and a Service GCMD Keyword. This concept is called "Subject" in the CSW Specification.

Metadata Use ConstraintsInformation about how the data may or may not be used after access is granted to assure the protection of privacy or intellectual property.

xPath Note: The xPaths included in this table 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.

Documenting ISO-1 metadata for Discovery

This table contains the metadata elements recommended for the discovery of data resources. These elements are are identified in Table F.1 of the ISO 19115-1 specification. Each of the element names is followed by an abbreviation to indicate the element obligation and max occurrence. The obligation options include M for Mandatory, O for Optional, or C for Conditional. The occurrence options are 1 or N for any number.
