We've actually been discussing this issue in a breakout from 'Data Citation Implementors Group', and I think we're currently leaning towards not relying solely on content negotiation, but also using HTTP Link headers or HTML link elements to make it possible to discover the other formats that the metadata may be available. I don’t know if the following is helpful or not, but CrossRef has implemented an API allowing the developer to use content negotiation to retrieve links to full text and/or metadata, and I wrote a hack to implement the idea — http://blogs.nd.edu/emorgan/2014/06/tdm/ —Eric Morgan
