The following NetCDF Attribute Convention for Data Discovery variable attributes are highly recommended for data usability.
ACDD variable attributes for Usability - Highly Recommended
Concept | Description | Dialect (Fit) Paths |
---|
Parameter Name (Standard) | The name of a parameter included in the resource from a standard vocabulary. | ISO-1 /mdb:MD_Metadata/mdb:contentInfo/mrc:MD_CoverageDescription/mrc:attributeGroup/mrc:MD_AttributeGroup/mrc:attribute/*/mrc:name/mcc:MD_Identifier/mcc:code/gco:CharacterString netCDF /nc:netcdf/nc:variable/nc:attribute[@nc:name='standard_name']/@nc:value

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.
