Hi Alan, CKAN is a repository for all kinds of datasets. Even if datasets are not open or only for non-commercial use, they can be listed and information on licensing can be noted (Other - Closed, e.g.). This is still a valuable information. If no license is specified or we did not find the license information, CKAN lists the datasets as "not open". Leigh Dodds had a closer look at the licenses of the LOD datasets some time ago [1]. It is sad but true that only about 23% of all datasets come along with a clearly defined license. Hopefully data publishers will more clearly state the licenses along with their datasets to encourage people to use their data.
