Data Discovery (DIF)
From Earth Science Information Partners (ESIP)
The spirals below provide required and highly recommended attributes for NASA's Directory Interchange Format (DIF). Where compatible the spirals provide xpath references for DIF, ECHO, ECS, DCAT, ISO, ISO-1 and FGDC documentation dialects.
==DIF for Data Discovery - Required==
The Directory Interchange Format (DIF) is a NASA metadata format used to create directory entries that describe scientific data sets. The attributes in the spiral below are required by the DIF standard. Additonal documentation is available via the following online references:

| Theme 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.

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.
