The spirals below document concepts 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, ISO-1 and FGDC dialects.
DCAT for Data Discovery - Mandatory
The Data Catalog Vocabulary (DCAT) is an RDF vocabulary designed to facilitate interoperability between data catalogs published on the Web. This spiral includes the required common core attributes for DCAT.
Source: Common Core Reference
| 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:MD_Metadata/mdb:identificationInfo/*/mri:citation/cit:CI_Citation/cit:title/gco:CharacterString ECHO /*/echo:ShortName>/*/echo:LongName DIF /dif:DIF/dif:Entry_Title DIF /dif:DIF/dif:Data_Set_Citation/dif:Dataset_Title ECS /*/ecs:ShortName > /*/ecs:LongName FGDC /fgdc:metadata/fgdc:idinfo/fgdc:citation/fgdc:citeinfo/fgdc:title DCAT dct:title |
| Abstract | A paragraph describing the resource. Note: This concept is called "Desciption" in Catalog Services for the Web. | ISO /*/gmd:identificationInfo/*/gmd:abstract/gco:CharacterString ISO-1 /mdb:MD_Metadata/mdb:identificationInfo/*/mri:abstract/gco:CharacterString ECHO /*/echo:Description DIF /dif:DIF/dif:Summary/dif:Abstract ECS /*/ecs:CollectionDescription ECS /*/ecs:LongName FGDC /fgdc:metadata/fgdc:idinfo/fgdc:descript/fgdc:abstract DCAT dct:description |
| 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. | ISO (1) /*/gmd:identificationInfo/*/gmd:descriptiveKeywords/gmd:MD_Keywords[gmd:type/gmd:MD_KeywordTypeCode='theme']/gmd:keyword/gco:CharacterString ISO-1 /mdb:MD_Metadata/mdb:identificationInfo/*/mri:descriptiveKeywords/mri:MD_Keywords[mri:type/mri:MD_KeywordTypeCode='theme']/mri:keyword/gco:CharacterString ECHO (1) /*/echo:ScienceKeywords/echo:ScienceKeyword/echo:CategoryKeyword ECHO (1) /*/echo:ScienceKeywords/echo:ScienceKeyword/echo:TopicKeyword ECHO (1) /*/echo:ScienceKeywords/echo:ScienceKeyword/echo:TermKeyword ECHO (1) /*/echo:ScienceKeywords/echo:ScienceKeyword/echo:VariableLevel1Keyword/echo:Value ECHO (1) /*/echo:ScienceKeywords/echo:ScienceKeyword/echo:VariableLevel2Keyword/echo:Value ECHO (1) /*/echo:ScienceKeywords/echo:ScienceKeyword/echo:VariableLevel3Keyword ECHO (1) /*/echo:ScienceKeywords/echo:ScienceKeyword/echo:DetailedVariableKeyword DIF (1) /dif:DIF/dif:Parameters/dif:Category DIF (1) /dif:DIF/dif:Parameters/dif:Topic DIF (1) /dif:DIF/dif:Parameters/dif:Term DIF (1) /dif:DIF/dif:Parameters/dif:Variable_Level_1 DIF (1) /dif:DIF/dif:Parameters/dif:Variable_Level_2 DIF (1) /dif:DIF/dif:Parameters/dif:Variable_Level_3 DIF (1) /dif:DIF/dif:Parameters/dif:Detailed_Variable ECS (1) /*/ecs:DisciplineTopicParameters/ecs:DisciplineKeyword ECS (1) /*/ecs:DisciplineTopicParameters/ecs:TopicKeyword ECS (1) /*/ecs:DisciplineTopicParameters/ecs:TermKeyword ECS (1) /*/ecs:DisciplineTopicParameters/ecs:VariableKeyword FGDC (1) /fgdc:metadata/fgdc:idinfo/fgdc:keywords/fgdc:theme/fgdc:themekey |
| Modified Date | Date on which the record was created or updated within the catalogue | ISO /*/gmd:dateStamp/gco:Date ISO /*/gmd:dateStamp/gco:DateTime ISO-1 /mdb:MD_Metadata/mdb:dateInfo/cit:CI_Date[cit:dateType/cit:CI_DateTypeCode="lastUpdate"]/cit:date/gco:DateTime ECHO /*/echo:LastUpdate DIF /dif:DIF/dif:DIF_Creation_Date ECS /*/ecs:RevisionDate |
| Publisher | Publisher of the cited resource | ISO //gmd:CI_Citation/gmd:citedResponsibleParty/gmd:CI_ResponsibleParty[gmd:role/gmd:CI_RoleCode = 'publisher'] ISO-1 //cit:CI_Citation/cit:citedResponsibleParty/cit:CI_Responsibility[cit:role/cit:CI_RoleCode='publisher']/cit:party/cit:CI_Organisation/cit:name/gco:CharacterString DIF /dif:DIF/dif:Data_Set_Citation/dif:Dataset_Publisher DIF /dif:DIF/dif:Reference/dif:Publisher DCAT dct:publisher |
| Resource Contact | The organization or person responsible for answering questions about the resource. | ISO /*/gmd:identificationInfo/*/gmd:pointOfContactPro ISO-1 /mdb:MD_Metadata/mdb:identificationInfo/*/mri:pointOfContact/cit:CI_Responsibility[cit:role/cit:CI_RoleCode='pointOfContact'] ECHO /*/echo:Contacts/echo:Contact DIF /dif:DIF/dif:Personnel[dif:Role='INVESTIGATOR'] ECS /CollectionMetaDataFile/CollectionMetaDataSets/Collections/CollectionMetaData/Contact[Role='User Services'] DCAT dct:person |
| Metadata Identifier | A phrase or string which uniquely identifies the metadata file/record. | ISO /*/gmd:fileIdentifier/gco:CharacterString ISO-1 /mdb:MD_Metadata/mdb:metadataIdentifier/mcc:MD_Identifier DIF /dif:DIF/dif:Entry_Id |
| 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 ISO-1 /mdb:MD_Metadata/mdb:identificationInfo/*/mri:resourceConstraints/mco:MD_Constraints ISO-1 /mdb:MD_Metadata/mdb:identificationInfo/*/mri:resourceConstraints/mco:MD_LegalConstraints ISO-1 /mdb:MD_Metadata/mdb:identificationInfo/*/mri:resourceConstraints/mco:MD_SecurityConstraints ECHO /*/echo:RestrictionFlag ECHO /*/echo:RestrictionComment ECHO /*/echo:Visible DIF /dif:DIF/dif:Access_Constraints ECS /*/ecs:AccessConstraints FGDC /fgdc:metadata/fgdc:idinfo/fgdc:accconst |
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.
