Glaciology

Standards Add

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.

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

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.

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.

Marine Community Profile Edit

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 Add

ANZ-MEST (Metadata Entry and Search Tool) Edit

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

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

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.

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.

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.
