Metadata Standards

CF (Climate and Forecast) Metadata Conventions

A standard for climate and forecast “use metadata” that aims both to distinguish quantities (such as physical description, units, or prior processing) and to locate the data in space–time.

CIM - Common Information Model

A model for describing numerical experiments carried out by the Earth system modelling community, the models they use, and the data they produce.

DIF - Directory Interchange Format

An early metadata initiative from the Earth sciences community, intended for the description of scientific data sets. It inlcudes elements focusing on instruments that capture data, temporal and spatial characteristics of the data, and projects with which the dataset is associated.

FGDC/CSDGM - Federal Geographic Data Committee Content Standard for Digital Geospatial Metadata

BGDC policy states that non-Federally authored standards that are endorsed by the FGDC have the same status as FGDC developed standards. Since ISO 19115 and the associated standards are endorsed by the FGDC, federal agencies are encouraged to transition to ISO metadata as their agencies are able to do so.

ISO 19115

An internationally-adopted schema for describing geographic information and services. It provides information about the identification, the extent, the quality, the spatial and temporal schema, spatial reference, and distribution of digital geographic data.

Extensions

Cruise Summary Reports

The National Oceanographic Data Centre's required format for reporting on cruises or field experiments at sea, formulated using tags from the ISO19115 metadata standard.

CSDGM Extensions for Remote Sensing Metadata

An extension to the FGDC/CSDGM metadata standard providing a common terminology and set of definitions for documenting geospatial data obtained by remote sensing.

EDMED Metadata Profile

The European Directory of Marine Environmental Datasets metadata scheme, which is a profile of ISO 19115.

INSPIRE Metadata Regulation

A profile of ISO 19115:2003, adopted in 2007 as the common metadata standard for the Infrastructure for Spatial Information in the European Community (INSPIRE). The other profiles of ISO 19115 in use in European Member States have been made compliant with INSPIRE.

ISO 19115-2 - Imagery and gridded data

An extension of ISO 19115 defining the schema required for describing imagery and gridded data.

Marine Community Profile

A profile developed in accordance with ISO 19115 rules by the Australian Ocean Data Centre that supports the documentation and discovery of marine spatial datasets.

Tools

ANZ-MEST - Metadata Entry and Search Tool

A GeoNetwork web application for metadata management and searching, with profiles available for two extensions of ISO 19115: ANZLIC and the Marine Community Profile.

CF Compliance Checker

A utility that checks netCDF files for CF-compliance.

CIM Tools

Tools for viewing and validating CIM metadata encoded in XML format.

CMOR - Climate Model Output Rewriter

A set of C-based functions, with bindings to both Python and FORTRAN 90, that can be used to produce CF-compliant netCDF files.

FGDC/CDSGM Tools

The FGDC website's list of tools to implement the CSDGM standard.

ncISO

A package of tools that facilitates the generation of ISO 19115-2 metadata from NetCDF data sources.

NetCDF

A set of software libraries and self-describing, machine-independent data formats that conform to the CF metadata conventions. They support the creation, access, and sharing of array-oriented scientific data.

PIMMS - Portable Infrastructure for the Metafor Metadata System

A methodology and toolset for documenting climatology simulation experiments using the Common Information Model(CIM).

SeaDataNet Software

A suite of tools designed by SeaDataNet to facilitate the creation, editing, and conversion of ocean and marine data and metadata. Particular tools are available for preparing ISO 19115-conformant XML metadata files for the SeaDataNet directories.

Use Cases

BADC - British Atmospheric Data Centre

The Natural Environment Research Council's (NERC) Designated Data Centre for the Atmospheric Sciences. It uses the CF-Compliant NetCDF format for its datasets.

BODC - British Oceanographic Data Centre Published Data Library

This national facility for looking after and distributing data concerning the marine environment requires that data sets use a well-documented format such as CF-compliant NetCDF and be accompanied by a Dublin Core record as well as discovery metadata in a recognised standard such as DIF or FGDC/CDGM.

CEOS International Directory Network

An international effort headed by the Committee on Earth Observation Satellites developed to assist users in locating Earth science data sets, data services, and visualizations using DIF metadata.

CMIP5 Metadata Questionnaire

A service for submitting CMIP5 climate data to the Earth Science Grid in a form compliant with the Common Information Model (CIM).

Common Data Index

A web service allowing users to access the availability and geographical spreading of marine data sets managed by the SeaDataNet data centres, using metadata based on the ISO 19115 content model.

Earth System Grid

A gateway providing a discovery service for climate data held at repositories across the globe. It supports use of the Common Information Model (CIM).

GFZ Information System and Data Center

A case study describing DIF metadata use in the German Research Center for Geoscience.

Global Change Master Directory

The GCMD uses DIF metadata to promote the discovery, access, and use of Earth science data and data-related services worldwide, parcitularly focusing on NASA data.

Met Office Hadley Centre

A number of projects at the Hadley Center require CF-Compliant NetCDF files, including HadAT and Transpose AMIP.

NASA EOSDIS - The Earth Observing System Data and Information System

EOSDIS provides online FTP access to thousands of Earth system science data products described with DIF metadata.

NCAR - National Center for Atmospheric Research

The NCAR Research Data Archive uses CF-Compliant NetCDF files.

NCDC - National Climatic Data Center

The world's largest climate data archive, providing climatological services and data worldwide. It currently promotes the FGDC/CSDGM metadata standard for its datasets.
