Agenda

We are a not-for-profit organisation dedicated to promoting openness in all its forms (data + content)

We build:Communities + Tools

The Open Knowledge Foundation

A piece of content or data is open if anyone is free to use, reuse, and redistribute it — subject only, at most, to the requirement to attribute and share-alike.

We can currently harvest: other CKAN catalogs, CSW endpoints and WAFs serving ISO 19139 documents

Federation
