DCAT for Data Discovery - Mandatory
These attributes are mandatory for the common core metadata specification based on the Data Catalog Vocabulary (DCAT). Where compatible the spirals below provide like xpath references for DIF, ECHO, ECS, UMM and ISO.
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. | DIF /dif:DIF/dif:Entry_Title DIF /dif:DIF/dif:Data_Set_Citation/dif:Dataset_Title 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 ISO /*/gmd:identificationInfo/*/gmd:citation/gmd:CI_Citation/gmd:title/gco:CharacterString ISO-1 /*/mdb:identificationInfo/*/rmd:citation/cit:CI_Citation/cit:title/gco:CharacterString |
Abstract | A paragraph describing the resource. | DIF /dif:DIF/dif:Summary/dif:Abstract ECHO /*/echo:Description ISO /*/gmd:identificationInfo/*/gmd:abstract/gco:CharacterString ISO-1 /*/mdb:identificationInfo/*/rmd:abstract/gco:CharacterString |
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. |
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 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 ECS (1) /ecs:CollectionMetaDataFile/ecs:CollectionMetaDataSets/ecs:Collections/ecs:CollectionMetaData/ecs:DisciplineTopicParameters/ecs:DisciplineKeyword ECS (1) /ecs:CollectionMetaDataFile/ecs:CollectionMetaDataSets/ecs:Collections/ecs:CollectionMetaData/ecs:DisciplineTopicParameters/ecs:TopicKeyword ECS (1) /ecs:CollectionMetaDataFile/ecs:CollectionMetaDataSets/ecs:Collections/ecs:CollectionMetaData/ecs:DisciplineTopicParameters/ecs:TermKeyword ECS (1) /ecs:CollectionMetaDataFile/ecs:CollectionMetaDataSets/ecs:Collections/ecs:CollectionMetaData/ecs:DisciplineTopicParameters/ecs:VariableKeyword ISO (1) /*/gmd:identificationInfo/*/gmd:descriptiveKeywords/gmd:MD_Keywords[gmd:type/gmd:MD_KeywordTypeCode='theme']/gmd:keyword/gco:CharacterString |
Modified Date | Date on which the record was created or updated within the catalogue | DIF /dif:DIF/dif:DIF_Creation_Date ISO /*/gmd:dateStamp/gco:Date ISO /*/gmd:dateStamp/gco:DateTime |
Publisher | Publisher of the cited resource | DIF /dif:DIF/dif:Data_Set_Citation/dif:Dataset_Publisher DIF /dif:DIF/dif:Reference/dif:Publisher 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 |
Resource Contact | The organization or person responsible for answering questions about the resource. | DIF /dif:DIF/dif:Personnel[dif:Role='INVESTIGATOR'] ECHO /*/echo:ArchiveCenter ECHO /*/echo:Contacts/echo:Contact ECS /CollectionMetaDataFile/CollectionMetaDataSets/Collections/CollectionMetaData/Contact[Role='User Services'] ISO /*/gmd:identificationInfo/*/gmd:pointOfContact |
Metadata Identifier | A phrase or string which uniquely identifies the metadata file/record. | DIF /dif:DIF/dif:Entry_Id ISO /*/gmd:fileIdentifier/gco:CharacterString |
Resource Contact | The organization or person responsible for answering questions about the resource. | DIF /dif:DIF/dif:Personnel[dif:Role='INVESTIGATOR'] ECHO /*/echo:ArchiveCenter ECHO /*/echo:Contacts/echo:Contact ECS /CollectionMetaDataFile/CollectionMetaDataSets/Collections/CollectionMetaData/Contact[Role='User Services'] ISO /*/gmd:identificationInfo/*/gmd:pointOfContact |
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. | DIF /dif:DIF/dif:Access_Constraints ECHO /*/echo:RestrictionFlag ECHO /*/echo:RestrictionComment ECS /ecs:CollectionMetaDataFile/ecs:CollectionMetaDataSets/ecs:Collections/ecs:CollectionMetaData/ecs:AccessConstraints 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 |
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.
