The spiral below is for the Common Core metadata specification based on the Data Catalog Vocabulary (DCAT). Where compatible the spiral provides like xpath references for DIF, ECHO, ECS, SERF, ISO and ISO-1.
DCAT for Data Discovery - Mandatory
Concept | Description | Dialect (Fit) Paths |
---|---|---|
Resource Title | A short description of the resource. The title should be descriptive enough so that when a user is presented with a list of titles the general content of the data set can be determined. | ISO /*/gmd:identificationInfo/*/gmd:citation/gmd:CI_Citation/gmd:title/gco:CharacterString ISO-1 /*/mdb:identificationInfo/*/mri:citation/cit:CI_Citation/cit:title/gco:CharacterString ECHO /*/echo:ShortName>/*/echo:LongName ECS /ecs:CollectionMetaDataFile/ecs:CollectionMetaDataSets/ecs:Collections/ecs:CollectionMetaData/ecs:ShortName> /ecs:CollectionMetaDataFile/ecs:CollectionMetaDataSets/ecs:Collections/ecs:CollectionMetaData/ecs:LongName DIF /dif:DIF/dif:Entry_Title DIF /dif:DIF/dif:Data_Set_Citation/dif:Dataset_Title |
Abstract | A paragraph describing the resource. Note: This concept is called "Desciption" in Catalog Services for the Web. |

Keyword | A 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. |

Resource Access Constraints | Information about any constraints for accessing the data set. This includes any special restrictions, legal prerequisites, limitations and/or warnings on obtaining the data set. Some words that may be used in this field include: Public, In-house, Limited, Additional detailed instructions on how to access the data can be entered in this field. | ISO /*/gmd:identificationInfo/gmd:MD_DataIdentification/gmd:resourceConstraints/gmd:MD_LegalConstraints/gmd:legalConstraints/gmd:MD_RestrictionCode ISO /*/gmd:identificationInfo/gmd:MD_DataIdentification/gmd:resourceConstraints/gmd:MD_LegalConstraints/gmd:otherConstraints/gco:CharacterString ISO /*/gmd:identificationInfo/srv:SV_ServiceIdentification/srv:restrictions/gmd:MD_LegalConstraints/gmd:legalConstraints/gco:CharacterString ISO /*/gmd:identificationInfo/srv:SV_ServiceIdentification/srv:restrictions/gmd:MD_LegalConstraints/gmd:otherConstraints/gco:CharacterString ECHO /*/echo:RestrictionFlag ECHO /*/echo:RestrictionComment ECS /ecs:CollectionMetaDataFile/ecs:CollectionMetaDataSets/ecs:Collections/ecs:CollectionMetaData/ecs:AccessConstraints DIF /dif:DIF/dif:Access_Constraints SERF /serf:DIF/serf:Access_Constraints |
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.
