   Support preservation of version snapshots during round-tripping 

3. Status
   colour Blue title Phase 1

   The URIs of the round-tripped resources must be the same as the original URIs

4. Status
   subtle true colour Blue title Phase 3

   Support lossless round-tripping.  (ie, if you export a resource, delete that resource and import there is no difference from if you had never performed any of those operations).

BagIt

1. Status
   subtle true colour Blue title Phase 2

   Single resource bags
   

2. Status
   subtle true colour Blue title Phase 2

   The structure and scope of accepted and produced BagIt bags must be configurable (resource)
   1. Clarification: structure relates to required and optional tagfiles in the bag
   2. Clarification: scope relates to contents of the bag, e.g. single object or object and all members based on specific membership predicate

3. Status
   subtle true colour Blue title Phase 3

   Multi-resource bags

4. Status
   subtle true colour Blue title Phase 3

   Unambiguously support linking between resources within a bag, and from resources in the bag to resources outside the bag
   1. e.g. for bagged resources A and B, if A contains statement <A> myns:rel <B>, then it is unambiguous that B is a resource in the bag.  Suppose some archive ingests the bag and exposes its contents as web resources with URIs P and Q. If the archive preserves intra-bag links, resource P will have statement <P> myns:rel <Q>.  Likewise, if A contains external link <A> myns:rel2 <http://example.org/outside/the/bag>, then an archive that preserves links will have <P> myns:rel2 <http://example.org/outside/the/bag>
