Data Discovery (ECS)
ECS for Data Discovery - Mandatory
These attributes are mandatory for Earth Observation System Data and Information Core System (ECS) metadata model.
| Concept | Description | Dialect (Fit) Paths |
|---|---|---|
| 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 |
| 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 |
| Title | ISO /*/gmd:identificationInfo[1]/*/gmd:citation/gmd:CI_Citation/gmd:title/gco:CharacterString |

| Distribution Contact | Contact information for the organization or individual that distributes the resource. | DIF /dif:DIF/dif:Data_Center/dif:Personnel/dif:Role ECHO /echo:Collection/echo:Contacts/echo:Contact ISO /gmd:MD_Metadata/gmd:distributionInfo/gmd:MD_Distribution/gmd:distributor/gmd:MD_Distributor/gmd:distributorContact/gmd:CI_ResponsibleParty ISO-1 /mdb:MD_Metadata/mdb:distributionInfo/mrd:MD_Distribution/mrd:distributor/mrd:MD_Distributor/mrd:distributorContact/cit:CI_Responsibility |
| 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 |
| Metadata Identifier | A phrase or string which uniquely identifies the metadata file/record. | DIF /dif:DIF/dif:Entry_Id ISO /*/gmd:fileIdentifier/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.
