Library data in Semantic Web formats
If you are aware of any data sets/sources that are not listed, feel free to add them to CKAN. You do not need to be the owner/maintainer of the data to add it and do not worry if you do not know all of the details.
After adding the package (or finding/editing an existing package!), give it the tag "lld" so that the Linked Library Data group maintainers can find it.
