I agree that **PEOPLE** just want to deposit, however **SYSTEMS** need to work out where that is :)

EPrints is simple, it is either "Inbox", "Review", or possibly "Archive" DSpace is much more complex, with a raft of "collections" the user could deposit into. > > ** concersation two ** C: Hello SWORD here is an object and some > authentication details S: Ok i've done that, the object is at this > "Location" - (HTTP HEADER) "object" - needs to be defined > C:Hello server i'd like to modify the metadata "edit-uri" relating to > this record A: OK done OR not a chance, the repository has taken > control of this record muhahahaha "modify the metadata" - needs to be collected.... into an agreed package > C: Hello server I'd like to modify the content of this item > "edit-media" URI A: As above (as above) > C: Hello server I have a replacement package for this old one > "Location" URI from before.

This is not a SWORD issue, directly.... however it *is* an issue SWORD needs to address: if we can't transfer data in a uniform manner, then the uniform transport mechanism is going to flounder. -- Ian Stuart.
