Service Discovery (SERF)

From Federation of Earth Science Information Partners

The Service Entry Resource Format (SERF) is a NASA documentation dialect for service discovery, selection and usage.

SERF for Service Discovery - Required

The Service Entry Resource Format (SERF) is the de-facto GCMD standard for describing data services and applications. This spiral includes the fields that are required by the SERF standard. Additonal documentation is available via the following online references:

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.
