The netCDF Group at Unidata has recommended netCDF attributes for data discovery. Where compatible the spirals below provide like xpath references for DIF, ECHO, ECS, UMM and ISO.

Attribute Convention for Data Discovery - Highly Recommended

These attributes are highly recommended by the Attribute Convention for Data 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. 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

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.
