The spirals below provide guidance for ISO 19115-1 data discovery recommendations. Where compatible XPath references are provided for the DIF, ECHO, ECS, DCAT, ISO, ISO-1 and FGDC documentation dialects.

==ISO-1 for Data Discovery - Mandatory==

This spiral includes mandatory ISO 19115-1 attributes for data discovery. This list of attributes was obtained from table F.1 of the ISO 19115-1 Specification.

==ISO-1 for Data Discovery - Conditional==

This spiral includes conditional ISO 19115-1 attributes for data discovery. This list of attributes was obtained from table F.1 of the ISO 19115-1 Specification.

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. 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.
