3. Open questions.
- Properly suppressing Server Managed Triples, how do we deal with ldp:contains.
- Meta-conversation about what are Fedora's SMTs and the workflow.
- Updating a properties of a resource requires a special header to GET and to PUT. Do we reverse the behaviour and get back the non-SMTs by default. But you are lacking some of the useful triples (lastModified).
- We expect that READ is a more common action than write.
- ldp:contains should be a SMTs, which makes (for Jared) suppressing SMTs by default a less enjoyable process.
- Having Fedora ignore SMTs included in a PUT does not seem to be a breaking change and could be done post-5.0.0 release.
- Should be able to update SMTs if you need to.
- How do you restore a Memento?
- Currently need to GET a Memento, set Fedora to relaxed mode, then restart and PUT with Prefer: handling=lenient; received=minimal
- Need to have relaxed mode on a per-request
- Is this an authZ question? Should only certain people be able to restore versions?
- What is the result of a restore? Do you get all the previous triples whether they are SMTs or not? That seems to be the consensus.
- Consensus is to use a new Prefer header to allow per request overwriting the entire resource including any SMTs.
- Will restoring a Memento result in restoring an older ACL? Consensus is NO, the Memento is separate. The link to the ACL is a static link added by the server and because the resource is not removed/re-added the current ACL will remain.
- Discussion to occur in Slack
- Changing interaction models?
- Currently there is no way to change between interaction models.
- Currently you can add types in the ldp: namespace, this should not be allowed.
- Make all resources versionable by default?
- Yes. Danny to create a JIRA to enable versioning. Also create JIRA to tag code that is used for enabling versioning for future review.
- Reviewing list of SMTs that Ben created
- Is the list full and complete?
- What is the expected behaviour in interacting with SMTs.
- "Anything that is created by the server" as the rule for SMTs?
- Anything created by the server, where if they did not exist the interaction would be indetermined.
- Any triples added to the resource as they are being generated on request. `ldp:contains` and some fixity ones. Also with RDF serialization.
- Also make sure that on the testing side we ensure the correct behaviour of SMTs.
