The subject line really says it all. To be a compliant
AtomPub client, when editing a resource must the client do a GET before doing a
PUT? The way I understand it, use of etags or modify dates as a part of
the exchange is not required (resulting in potential overwrite problems).
Yet if a server did require that, say, eTags be used then PUT requests lacking
the eTag could result in an error code (not sure which) which could be
interpreted to mean, “do a GET and use the eTag to retry your PUT”. Thanks, Cornelia Cornelia
