Data Discovery (ECS)
The spiral below lists mandatory attributes for the Earth Observation System Data and Information Core System (ECS) metadata model. Where compatible the spiral provides like xpath references for DIF, ECHO, ECS, SERF, ISO and ISO-1.
ECS for Data Discovery - Mandatory
| Concept | Description | Dialect (Fit) Paths |
|---|---|---|
| Resource Contact | The organization or person responsible for answering questions about the resource. | ISO /*/gmd:identificationInfo/*/gmd:pointOfContact ISO-1 /mdb:MD_Metadata/mdb:identificationInfo/mri:MD_DataIdentification/mri:pointOfContact/cit:CI_Responsibility ECHO /*/echo:ArchiveCenter ECHO /*/echo:Contacts/echo:Contact ECS /CollectionMetaDataFile/CollectionMetaDataSets/Collections/CollectionMetaData/Contact[Role='User Services'] DIF /dif:DIF/dif:Personnel[dif:Role='INVESTIGATOR'] SERF /serf:SERF/serf:Personnel |
| 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:identificationInfo/*/rmd:abstract/gco:CharacterString ECHO /*/echo:Description ECS /ecs:CollectionMetaDataFile/ecs:CollectionMetaDataSets/ecs:Collections/ecs:CollectionMetaData/ecs:CollectionDescription DIF /dif:DIF/dif:Summary/dif:Abstract SERF /serf:SERF/serf:Summary/serf:Abstract |
| Distribution Contact | Contact information for the organization or individual that distributes the resource. | 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 ECHO /echo:Collection/echo:Contacts/echo:Contact DIF /dif:DIF/dif:Data_Center/dif:Personnel/dif:Role SERF /serf:SERF/serf:Service_Provider |

| Title | ISO /*/gmd:identificationInfo[1]/*/gmd:citation/gmd:CI_Citation/gmd:title/gco:CharacterString |
|
| 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 SERF /serf:SERF/serf:Entry_ID |
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.
