OTMI Nature might not quite be in the Open Publishing business like PLoS, but they are an important player nevertheless. I hope the OTMI gets picked up by other publications. It would be nice to have a publication data standard and as one of the top two scientific journals, Nature has the clout to make this happen. Being able to mine journals and search for information is invaluable (open or otherwise), and using standard formats like OPML is an excellent idea.
