Agenda

1. Welcome to new Fedora Committer: Yinlin Chen
2. Alignment Sprint 1 Progress ReportReport  https://jira.duraspace.org/issues/?filter=14401
   1. Memento-Datetime header granularity issue RFC-1123
      1. The memento spec does not support version sub-second granularity 
      2. There is no problem with us supporting it internally (when creating mementos without specifying the header).
      3. However is we support sub-second granularity it is not clear how we will be able to import versions without losing information.
      5.7.3 LDP-NR - Patching Binaries (LDP-NR) - do we plan to support?

   2. Jira
      server DuraSpace JIRA serverId c815ca92-fd23-34c2-8fe3-956808caf8c5 key FCREPO-2710

   3. Challenges with acl:Append
      1. https://fcrepo.github.io/fcrepo-specification/#append-ldprs
      2. The spec defines rules at the HTTP method layer while the ACLs are implemented in the jcr layer.
      3. It makes it difficult to determine whether a POST, PUT or PATCH has occurred and whether a node existed when the transaction began.
      4. The javax.jcr.Node interface uses the same permsission (org.modeshape.jcr.SET_PROPERTY) for adding, updating and removing properties and generates the same:

   1. https

   4. The javax.jcr.Node interface uses the same method call (setProperty() for adding, updating and removing properties.

Minutes

Separate tickets

1. Creating Mementos when not providing Memento-Datetime
   • no body
2. Converting dynamic properties to static properties

Other

1. ACTION: BenP to submit an initial, minimal PR for creating no-body LDPRv's

Updates from spec editors meeting

...

Regarding 2.a:

• Two options:

  • Reduce the granularity of our label  

  • Modify Memento spec

• Consensus on option 1.
  • Return 409 when timestamps conflict.
• Agreement that server-managed or distributed backends could have trouble with that

• https://jira.duraspace.org/browse/FCREPO-2727 & https://jira.duraspace.org/browse/FCREPO-2728

Bethany Seeger & awoods:

Memento Tools - Validator: http://mementoweb.org/tools/validator/

Regarding 2c:  Consensus seems to be that we should plan to that pull the webac out of the modeshape layer and handle it at the http layer.  That would both solve the problem with supporting acl:Append and reduce our dependency on modeshape paving the way for swapping it with something else.

Regarding 3. external content pr

pull/343

Use POST/PUT requests to create external content nodes.

Consensus on proposed API changes. 

Action Items

•  Danny Bernstein determine whether there is any case where a PUT on a TimeMap would make sense. If there is it should be raised with the specification editors.
•  Peter Eichman to do a short writeup on the use of userAgent and groupAgent base URI's and their relationship to WebAC in order to clarify whether or not what if anything needs improvement/clarification/alignment. ACL Agents - Strings vs. URIs
