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).
Some repositories have decided that current standards do not fit their metadata needs, and so have created their own requirements.
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.
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
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.
