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.
