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.
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).
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.
The European Directory of Marine Environmental Datasets metadata scheme, which is a profile of ISO 19115.
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.
An extension of ISO 19115 defining the schema required for describing imagery and gridded data.
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.
A GeoNetwork web application for metadata management and searching, with profiles available for two extensions of ISO 19115: ANZLIC and the Marine Community Profile.
OWSLib is a Python package for client programming with Open Geospatial Consortium (OGC) web service (hence OWS) interface standards, and their related content models
pycsw is an OGC CSW server implementation written in Python. Started in 2010 (more formally announced in 2011), pycsw allows for the publishing and discovery of geospatial metadata via numerous APIs (CSW 2/CSW 3, OpenSearch, OAI-PMH, SRU), providing a standards-based metadata and catalogue component of spatial data infrastructures. pycsw is Open Source, released under an MIT license, and runs on all major platforms (Windows, Linux, Mac OS X)
pygeometa is a Python package to generate metadata for geospatial datasets
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.
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.
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.
EOSDIS provides online FTP access to thousands of Earth system science data products described with DIF metadata.
