Version control for datasets

Is there any work being done on some kind of version control for datasets? I know that there's an extension that provides some of this functionality, and a way to view differences between metadata of different versions was added to the CKAN core a few months ago by @davidread. However, there isn't currently a way to view old versions of resources, or to compare different versions of resource files, or to revert to old versions of datasets, all of which could be really useful.

Start by reviewing the referenced extension and the CKAN core work that added metadata version comparisons. The issue names no files, tests, or entry points and proposes several capabilities; a maintainer would need to define the scope and acceptance criteria before implementation can begin.
