Data Discovery (ACDD)
From Earth Science Information Partners (ESIP)
Nearly a decade ago, the netCDF Group at Unidata recommended a set of netCDF attributes (the NetCDF Attribute Convention for Dataset Discovery) to enable data discovery. This convention was designed to augment the Climate-Forecast conventions that were already being used to facilitate data accessibility in netCDF via tools. The ACDD was adopted as the basis for the ncISO tool developed at NGDC and incorporated into THREDDS with the goal of providing ISO 19115-compliant discovery metadata for datasets in THREDDS that supported the ACDD. The governance of these conventions has since been taken over by the ESIP Documentation Cluster.
This page includes ACDD recommendations at three levels: highly recommended, recommended, and suggested.

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.
