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
These attributes are mandatory for ECS
| Concept | Description | Dialect (Fit) Paths |
|---|---|---|
| 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 ECS /*/ecs:ArchiveCenter SERF /serf:SERF/serf:Service_Provider |
| 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 SERF /serf:SERF/serf:Summary/serf:Abstract |
| Processor | Identification of, and means of communication with, person(s) and organisation(s) associated with the process step. | ISO /*/gmd:dataQualityInfo/gmd:DQ_DataQuality/gmd:lineage/gmd:LI_Lineage/gmd:processStep/gmd:LI_ProcessStep/gmd:processor ISO-1 /mdb:MD_Metadata/mdb:resourceLineage/mrl:LI_Lineage/mrl:processStep/mrl:LI_ProcessStep/mrl:processor ECS /*/ecs:ProcessingCenter |

| 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 SERF /serf:SERF/serf:Entry_Title |
| Version Description | A brief description of the differences between this collection version and another collection version. | ECS /*/ecs:VersionDescription |
| Version | Version of the cited resource | ISO //gmd:CI_Citation/gmd:edition/gco:CharacterString ISO-1 /mai:MI_Metadata/mdb:identificationInfo/rmd:MD_DataIdentification/mri:citation/cit:CI_Citation/cit:edition/gco:CharacterString ECHO /*/echo:VersionId DIF /dif:DIF/dif:Data_Set_Citation/dif:Dataset_Version DIF /dif:DIF/dif:Reference/dif:Edition ECS /*/ecs:VersionId |
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.
