- Thought exercise: "What would be the technical "risks" of releasing 4.0 Production *now*"?
- Or another way, "Where do we want to put next sprint's dev energy"?

Discussion
Adam begins with API:
Base specification LDP plus base ontology but bytestreams
Possibly add transactions (suitable for web scale, not XA, JCR spec)
Thoughts about container:
Objects plus datastreams (fedora)
External to repo
Esme: other objects in repo
Andrew: question do we want to support
Adam: has different guarantees if outside
Adam: Need to think out ramifications for different kinds of outside items
Dan: Could have some overlap with issues about tiered storage
Adam: Not absolutely required for LDP
Andrew: Member, Reference, Indirect Container (need definitions)
Dan: Considerations of asynchronous responses (overlaps burden for remote operations)
Andrew: Need to define proposal for tiers
Adam: Keep core simplest possible
Andrew: We need to review what we have, LDP, is the interaction model logical, clean, does it represent what we expect out of the repository
Adam: Did we make a good guess for the implementation? Test on real world usage.
Adam, Andrew: Specification with dependencies for transactions, versioning, locking, etc.
Andrew to Adam: Can you flesh out all the tiers?
Adam: Will try for week from today
Esme: Should conversation be on Fedora tech list
All: yes
Performance Scenarios (Dan)
- Fixity checking
- Real-world scenarios
- Cache and no-Cache
- Look at direct REST client for Python
- Setting up environment (Scott Prater may have done some work)
- Many folks could contribute tests
RDF and Sparql Update well underway for next period (Esme)
- Adam and Ben to detail proposed partitioning of API
- All to review "Preservation Worthiness" description for next week's discussion
