Thanks for your efforts James. I think tombstones is really important for offering RESTful data synchronization services in the digital repository space where OAI-PMH has traditionally been used.
I have been using Tombstones at the Library of Congress. Having the draft make it to RFC will be very helpful in promoting the use of Atom within the digital preservation community. //Ed [1] http://www.openarchives.org/OAI/openarchivesprotocol.html
