Service Identification

Identifier	Title / Description	Value Domain	Card	Condition	Specific mapping notes	Guidelines	Example
SRTYPE [DMF/Services]	Service Type A service type name.	String Default is unknown	1			For OGC Web Services, the value defined by the applicable OGC Specification has to be used (e.g. 'WMS', WFS', 'CSW', 'WMTS', ... )
SRTVER [DMF/Services]	Service Type Version Version of the service type.	String Default is unknown	1			For OGC Web Services, the value defined by the applicable OGC Specification has to be used.
SRSTD [DMF/Services]	Service Standard Standard to which the service adheres.	Citation	0..1			This element can be used to mention to which DGIWG profile the service is compliant with.
SRCPLING [DMF/Services]	Service Coupling Type Type of coupling between service and associated data (if exists)	Coupling Type Codelist Default is loose	1
SROPRS [DMF/Services]	Resource Operated by the Service Provides a reference to the dataset on which the service operates	URI (URI of the metadata of the dataset on which the service operates.)	0..*	Mandatory if coupling type is tight or mixed.	The domain value of SROPRS is the URI of the metadata of the dataset on which the service operates. Mandatory when coupling type is tight or mixed. For one resource either operatedDataset or operatesOn may be used (not both for the same resource).
SROPER [DMF/Services]	Service Operation Provides information about the operations that comprise the service	Service Operation	1..*
SRCORS [DMF/Services]	Service Coupled Resource Further description of the data coupling in the case of tightly coupled services. It links a given operationName with a data set identified by an “identifier". And it requires that a given operationName or identifier shall refer to an existing operationName given by SROPER.name or an identifier given by RSID.code, respectively.	Service Coupling	0..*	Only applicable to tightly coupled services.

DMF/Core	DMF/Core defines the minimum set of metadata elements to be implemented by any metadata catalogue. This set satisfies the discovery use case.
DMF/Common	DMF/Common is an additional set of metadata elements for a more complete description of any type of resource supported by DMF. It extends DMF/Core and covers discovery and basic evaluation use cases.
DMF/Service	DMF/Services extends DMF/Core for service metadata and can be used together with DMF/Common (i.e. it is possible to use DMF/Services on top of DMF/Core (if DMF/Common elements are not needed) or on top of DMF/Common for an extensive profile).
