Registry of Open Access Repositories

CKAN - the Data Hub


The statistics currently shown are wrong but the harvesting operations should restart over the summer.

We are doing everything we can to bring the service back to normal and we apologise for the interruption to the service.

CKAN is the Comprehensive Knowledge Archive Network, a registry of open knowledge packages and projects (and a few closed ones). CKAN makes it easy to find, share and reuse open content and data, especially in ways that are machine automatable. As a system CKAN functions as a synthesis of several different services: it combines the features of a listing/registry, a package index and a wiki. As a registry it acts like freshmeat but for open data and content resources. However it adds to a simple registry in key ways. First, thanks to its underlying versioned domain model CKAN has a wiki-like interface that lets anyone add and material held in it. Second, and unlike a wiki, CKAN can store 'structured' information, which allows it to provide 'index'-like features such as automated registration, discovery and installation of material. In this respect it behaves like CPAN or PyPI in the software world -- though again for open data and content not code.
