Standards Add

CF (Climate and Forecast) Metadata Conventions Edit

The CF standard was originally framed as a standard for data written in netCDF format, with model-generated climate forecast data particularly in mind. However, it is equally applicable to observational datasets, and can be used to describe other formats. It is a standard for “use metadata” that aims both to distinguish quantities (such as physical description, units, and prior processing) and to locate the data in space–time.

Sponsored by the NetCDF Climate and Forecast Metadata Convention, the current version dates from December 2011.

DIF (Directory Interchange Format) Edit

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. It is defined as a W3C XML Schema.

Sponsored by the Global Change Master Directory, the DIF Writer's Guide Version 6 is from November 2010.

FGDC/CSDGM (Federal Geographic Data Committee Content Standard for Digital Geospatial Metadata) Edit

A widely-used, but no longer current standard defining the information content for a set of digital geospatial data required by the US Federal Government.

CSDGM was sponsored by the US Federal Geographic Data Committee.  However, in September 2010 the FGDC endorsed ISO 19115 and began encouraging federal agencies to transition to ISO metadata.

ISO 19115 Edit

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.

Sponsored by the International Standards Organisation, the first edition of ISO 19115 was published in 2003. It has since been split into parts: ISO 19115-1:2014 contains the fundamentals of the standard; ISO 19115-2:2009 contains extensions for imagery and gridded data; and ISO/TS 19115-3:2016 provides an XML schema implementation for the fundamental concepts compatible with ISO/TS 19138:2007 (Geographic Metadata XML, or GMD).

Extensions Add

COARDS Conventions Edit

Developed by the Cooperative Ocean-Atmosphere Research Data Service (COARDS), these conventions constitute a standard set of metadata to include in netCDF files, allowing them to be shared and interchanged.

The COARDS Conventions are generalized and extended by the CF (Climate and Forecast) Metadata Conventions.

Cruise Summary Reports Edit

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 Edit

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 Edit

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

INSPIRE Metadata Regulation Edit

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 Edit

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

Tools Add

FGDC/CDSGM Tools Edit

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

SeaDataNet Software Edit

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 Add

Australian Ocean Data Network Portal Edit

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 Edit

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 Edit

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) Edit

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 Edit

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 Edit

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 Edit

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 Edit
Marine Geoscience Data System Edit

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 Edit

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

NCDC (National Climatic Data Center) Edit

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 Edit

Ocean Networks Canada operates the world-leading 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.
