Requirements
External Systems
- Support import from and export to a TBD list of external systems.
- APTrust - University of Maryland (Joshua Westgard)
- Archivematica - Artefactual Systems (Justin Simpson)
- LOCKSS - Simon Fraser (Mark Jordan)
General
- Support transacting in Fedora-compliant RDF
RDF
- Support allowing the option to include Binaries
- Support references from exported resources to other exported resources
- Support transacting in BagIt bags
- Support import into a non-existing Fedora container
- Support import into an existing, empty Fedora container
- Support import into an existing, non-empty Fedora container with various policies: add, overwrite, delete, version, skip
- Support export of resource versions
- Support import of resource versions
- Support export of resource and its "members" based on the ldp:contains predicate
- Support export of resource and its "members" based on a user-provided membership predicate
Support recursive RDF insert/updates with LDP Indirect Container specified POST (and PUT / PATCH?) (ref: FCREPO-2042)- Consider import/export performance as is possible under the assumption that this work is done via the REST interface
Round-tripping
Defined as: Export all or a subset of a Fedora repository and importing the export artifacts into a Fedora repository.
- Support preservation of dates during round-tripping
- Support preservation of version snapshots during round-tripping
- The URIs of the round-tripped resources must be the same as the original URIs
- 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
- Single resource bags
- The structure and scope of accepted and produced BagIt bags must be configurable (resource)
- Clarification: structure relates to required and optional tagfiles in the bag
- Clarification: scope relates to contents of the bag, e.g. single object or object and all members based on specific membership predicate
- Multi-resource bags
- Unambiguously support linking between resources within a bag, and from resources in the bag to resources outside the bag
- 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>
Considerations
