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.

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.

Tools

FGDC/CDSGM Tools

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

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

Australian Ocean Data Network Portal

This portal is the primary access point for search, discovery, access and download of data collected by the Australian marine community. Uses the Marine Community Profile extension of ISO 19115

BAS PDC - British Antarctic Survey Polar Data Centre

An organisation coordinating the management of data collected by UK-funded scientists in the polar regions, using an application profile that is harmonious with both ISO 19115 and DIF.

BGS NGDC - British Geological Survey National Geoscience Data Centre

The world's oldest national geological survey and the United Kingdom's premier centre for earth science information and expertise, with information access via an ISO 19115-compliant discovery metadata database.

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.

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.

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.

Integrated Marine Observing System Portal
This portal is the primary access point for search, discovery, access and download of data collected by the Integrated Marine Observing System (IMOS), an Australian Government Research Infrastructure project. Uses the Marine Community Profile extension of ISO 19115
Marine Geoscience Data System

An online portal providing access to a number of NSF-supported marine geoscience projects, which has developed its own metadata requirements.

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.

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.

Ocean Networks Canada

Ocean Networks Canada operates the NEPTUNE and VENUS cabled ocean observatories that collect data on physical, chemical, biological, and geological aspects of the ocean over long time periods, supporting research on complex Earth processes. The CF standard is used within netCDF data products delivered through the Oceans 2.0 interface and via OPeNDAP webservices.
