pycsw
================================================================================

Metadata Catalog
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

pycsw is an OGC CSW server implementation written in `Python`_.

pycsw implements clause 10 (HTTP protocol binding (Catalogue Services for the Web, CSW)) of the `OpenGIS Catalogue Service Implementation Specification`_, version 2.0.2.  Initial development started in 2010 (more formally announced in `2011`_).

pycsw allows for the publishing and discovery of geospatial metadata.  Existing repositories of geospatial metadata can be exposed via OGC:CSW 2.0.2.

pycsw is `Open Source`_, released under an MIT :ref:`license <license>`, and runs on all major platforms (Windows, Linux, Mac OS X).
