Glacier inventory not showing up The expected functionality is *not* to show archives unless they were uploaded by Cloudberry? Seriously? While you are right - there are no tags that are created automatically, what difference does it make?
First, user may create archive description during upload... just like Cloudberry does - only more meaningful to the user. So you can show ArchiveDescription field, regardless how it was created.
Second, even if there is no Description, - there is still ArchiveId (meaningless, of course); but also creation date and size. Finally, there is a hash - so I can check for duplicates by sorting on hash.
In summary, not showing archives at all sounds like a bug... And to say that it is expected functionality is very strange, to say the least.
