| Concept | Description | Dialect (Fit) Paths |

| Metadata Identifier | A phrase or string which uniquely identifies the metadata file/record. | DIF /dif:DIF/dif:Entry_Id ISO /*/gmd:fileIdentifier/gco:CharacterString |
| Publication Date | Date of publication of the cited resource | DIF /dif:DIF/dif:Data_Set_Citation/dif:Dataset_Release_Date DIF /dif:DIF/dif:Reference/dif:Publication_Date ISO //gmd:CI_Citation/gmd:date/gmd:CI_Date[gmd:dateType/gmd:CI_DateTypeCode='publication']/gmd:date/gco:Date ISO //gmd:CI_Citation/gmd:date/gmd:CI_Date[gmd:dateType/gmd:CI_DateTypeCode='publication']/gmd:date/gco:DateTime ISO-1 //cit:CI_Citation/cit:date/cit:CI_Date[gmd:dateType/gmd:CI_DateTypeCode='publication']/cit:date/gco:Date |

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.
