 * **ckan2pycsw**: Software to achieve interoperability with the open data portals based on CKAN. To do this, ckan2pycsw reads data from an instance using the CKAN API, generates ISO-19115/ISO-19139 metadata using [pygeometa](https://geopython.github.io/pygeometa/), or a custom schema that is based on a customized CKAN schema, and populates a [pycsw](https://pycsw.org/) instance that exposes the metadata using CSW and OAI-PMH.
