What a great tool this CKAN is! With CKAN it's all about open data. It's a powerful data management system that makes data accessible – by providing tools to streamline publishing, sharing, finding and using data. CKAN is aimed at data publishers (national and regional governments, companies and organizations) wanting to make their data open and available. And we managed to install CKAN for our platform on a Amazon Web Service.

Currently we are internally improving the system, but as soon as it is public, I will update it here. But here a first screenshot:
