A significant outcome of the E2EOA project (Glasgow, Lancaster, Southampton and Kent) is the metadata profile/specification for Open Access.
The key idea for this metadata profile is that it supersedes any system related profiles. Instead it provides a comprehensive starting point from where you can adopt the profile to your liking in the system of your choice. The metadata profile is crowd sourced for larger consultation and can be viewed at:

As noted in an earlier post on the Jisc Scholarly Communications blog post, this metadata profile is also currently being looked at by Jisc/ CASRAI UK pilot for possible adoption as a standard.
The specification is open for comment currently (please contact Valerie McCutcheon@ valerie.mccutcheon@glasgow.ac.uk), but please do keep up-to-date with the project blog for more information.
