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 ISO-1 /*/mdb:identificationInfo/*/mri:citation/cit:CI_Citation/cit:title/gco:CharacterString ECHO /*/echo:ShortName>/*/echo:LongName ECS /ecs:CollectionMetaDataFile/ecs:CollectionMetaDataSets/ecs:Collections/ecs:CollectionMetaData/ecs:ShortName> /ecs:CollectionMetaDataFile/ecs:CollectionMetaDataSets/ecs:Collections/ecs:CollectionMetaData/ecs:LongName 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.
