Hi all, Been doing a bit of research in the list archives to answer a question for myself and have ended up more confused. Any help from old hands or current implementers appreciated. Looking at how to indicate that a resource is a translation of another resource, I assumed that isVersionOf / hasVersion were the appropriate refinements on Relation. The current usage guidelines don't appear to be very much in agreement with this: "The described resource is a version, edition, or adaptation of the referenced resource. Changes in version imply substantive changes in content rather than differences in format." Is a translation a "substantive change in content"? I found some very old emails in the list archive that indicated that isBasedOn / isBasisFor were once supposed to be used for translations. I can't tell if this was ever actually included in recommended DC, or if it was just an early discussion. The complexity is increased by the fact that our system is structured on IEEE LOM metadata, but we offer crosswalks to Dublin Core- but the LOM *does* include the terms isBasedOn / isBasisFor as well as the Version ones. Not sure if the LOM once upon a time based its vocabulary on the then-DC vocabulary, or if something else happened, but I guess its irrelevant now :-) Is it the case that isVersionOf / hasVersion are now used to indicate a translation relationship?
