Service Discovery (ISO 19115-1)
The spirals below provide guidance regarding ISO 19115-1 recommendations for service discovery.
This spiral includes mandatory ISO 19115-1 attributes for Service discovery. This list of attributes was obtained from table F.2 of the ISO 19115-1 Specification.
Source: ISO-1 Metadata for Service Discovery| 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. | ECS /*/ecs:ShortName > /*/ecs:LongName ECHO /*/echo:ShortName>/*/echo:LongName DIF /dif:DIF/dif:Entry_Title DIF /dif:DIF/dif:Data_Set_Citation/dif:Dataset_Title SERF /serf:SERF/serf:Entry_Title FGDC /fgdc:metadata/fgdc:idinfo/fgdc:citation/fgdc:citeinfo/fgdc:title DCAT /dct:title 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 |
| Bounding Box | A bounding box for identifying a geographic area of interest Note: This concept is called "Coverage" in the CSW Specification | ECS /*/ecs:Spatial/ecs:HorizontalSpatialDomain/ecs:BoundingRectangle ECHO /*/echo:Spatial/echo:HorizontalSpatialDomain/echo:Geometry/echo:BoundingRectangle DIF /dif:DIF/dif:Spatial_Coverage FGDC /fgdc:metadata/fgdc:idinfo/fgdc:spdom/fgdc:bounding DCAT /dct:spatial ISO /*/gmd:identificationInfo/gmd:MD_DataIdentification/gmd:extent/gmd:EX_Extent/gmd:geographicElement/gmd:EX_GeographicBoundingBox ISO /*/gmd:identificationInfo/srv:SV_ServiceIdentification/srv:extent/gmd:EX_Extent/gmd:geographicElement/gmd:EX_GeographicBoundingBox ISO-1 /mdb:MD_Metadata/mdb:identificationInfo/*/mri:extent/gex:EX_Extent/gex:geographicElement/gex:EX_GeographicBoundingBox |
| Abstract | A paragraph describing the resource. Note: This concept is called "Desciption" in Catalog Services for the Web. | ECS /*/ecs:CollectionDescription ECHO /*/echo:Description DIF /dif:DIF/dif:Summary/dif:Abstract SERF /serf:SERF/serf:Summary/serf:Abstract FGDC /fgdc:metadata/fgdc:idinfo/fgdc:descript/fgdc:abstract DCAT /dct:description ISO /*/gmd:identificationInfo/*/gmd:abstract/gco:CharacterString ISO-1 /mdb:MD_Metadata/mdb:identificationInfo/*/mri:abstract/gco:CharacterString |

| Resource Type | A resource code identifying the type of resource e.g. dataset, a collection, an application (see MD_ScopeCode) which the metadata describes. | ISO /gmd:MD_Metadata/gmd:hierarchyLevel/gmd:MD_ScopeCode ISO-1 /mdb:MD_Metadata/mdb:metadataScope/mdb:MD_MetadataScope/mdb:resourceScope/mcc:MD_ScopeCode |

| Coupled Resource | Identifier and name of the dataset to which the service is coupled. | ISO /*/gmd:identificationInfo/srv:SV_ServiceIdentification/srv:coupledResource ISO-1 /mdb:MD_Metadata/mdb:identificationInfo/srv:SV_ServiceIdentification/srv:coupledResource |
| Coupled Type | Describes the tightness of the coupling to the coupled resource. | ISO /gmd:MD_Metadata/gmd:identificationInfo/srv:SV_ServiceIdentification/srv:couplingType ISO-1 /mdb:MD_Metadata/mdb:identificationInfo/srv:SV_ServiceIdentification/srv:couplingType |
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. 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.
