Background
pycsw fully implements the OpenGIS Catalogue Service Implementation Specification [Catalogue Service for the Web]. Initial development started in 2010 (more formally announced in 2011). The project is certified OGC Compliant, and is an OGC Reference Implementation.[1] Since 2015, pycsw is an official OSGeo Project.
pycsw allows for the publishing and discovery of geospatial metadata via numerous APIs (CSW 2/CSW 3, OpenSearch, OAI-PMH, SRU). Existing repositories of geospatial metadata can also be exposed, providing a standards-based metadata and catalogue component of spatial data infrastructures.
Deployment
pycsw is used in government, academia and industry, and powers the Geoplatform.gov and Data.gov CSW services.[2] Data.gov is the home of the U.S. Government’s open data. pycsw can be deployed both as a standalone and embedded component in geospatial data portal applications such as CKAN, GeoNode, and Open Data Catalog.[3]
