2. Summary of the Problem
Exchange of digital content between repository platforms is challenging
Different data models, metadata, semantics, interfaces
Current state of the art (e.g. Dublin Core, OAI-PMH, SWORD) well adopted but very limited
Upcoming approaches (e.g. Linked Data Platform, Resource Sync, OAI-ORE) supported by a comparable small subset of platforms
Some varied use cases: migration, replication, cross-domain sharing
Migration between same platform, but different version
Replication between different locations
Share with domain and cross-domain scientists

3. Status of the Deliverable
D1. Research Data Repository Interoperability Primer (M6)
Use Case description, state of the art and gap analysis
Foundation for further discussions
DOI: /RDA00020
D2. Interface Specification Draft (M12)
Will define no interface but adoptable recommendations
Active WG members agreed on BagIt-based approach
Recommend to follow the BagIt specification as far as possible
Recommend to include basic metadata in well-known standard schema, e.g. Datacite 4.0
Recommend to provide machine readable profile information

4. Initial Adopters
First prototype implementation can start as soon as D2 is finished
Create first profile definition(s) for well-known packages
Fedora, DataONE, Data Conservancy, Research Object, DARIAH
Talk to developers of existing BagIt-based packaging solutions
Ask to include basic metadata
Create new / correct existing profile
Demonstrate at least one example migration/replication between two platforms

5. Expected Impact of the Deliverable
Recommendations that are comparably easy to adopt
Support for both state-of-the-art and legacy platforms
Provide users with a common tool to e.g. transport, exchange or backup their content
Basis for further agreements of package content to improve interpretability of package content

6. Feedback Desired from RDA Community
From Platform Developers:
How do you assess the applicability for your platform?
Where do you see challenges/obstacles for an adoption?
Do you want to be an adopter?
From Platform Users:
Do you think our approach will help you?
What do you think is missing?
