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

SERF for Service Description - Required

Concept Description Dialect (Fit) Paths
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
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

DIF /dif:DIF/dif:Entry_Title
DIF /dif:DIF/dif:Data_Set_Citation/dif:Dataset_Title
Keyword A word or phrase that describes some aspect of a resource. Can be one of several types.

Note: The general identification keywords usually have a type of "theme" and are refered to as "theme keywords". Other types and vocabularies are used for other information. Service Entry Resource Format (SERF) requires a Science and a Service GCMD Keyword. This concept is called "Subject" in the CSW Specification.

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.
