Agenda:

1. Call for Agenda Items
2. Versioning for ActiveFedora if we upgrade to ActiveTriples 0.4.0 (https://github.com/projecthydra/active_fedora/pull/500)
   1. Should we have ActiveFedora 8 for what is currently on master, and make fedora-4 target ActiveFedora 9?
      1. Justin: Tom's pull request will break a few things, with active work toward Fedora-3 and Fedora-4, with different dependencies etc.
         1. proposed solution: go to four-number scheme, with least-significant keyed to Fedora version? Should send this out for discussion; potential for confusion is great. Or: create AF3 gem. Will write up and send out.
3. WebAccessControl
   
   1. How do the Hydra, Islandora and Fedora communities work together to come up with a common access control strategy that works for everyone?
      1. update (Justin) - pull request in Hydra head - keeps Hydra API on back end, serializes to standard - nearly ready to merge into Fedora 4 - would like feedback this week: https://github.com/projecthydra/hydra-head/pull/211
      2. process (Esmé) - how can we move this forward? What forum? - this call for Hydra community; 
         1. would like to add to Fedora as third option for access control
      3. other communities: Islandora (Nick Ruest): is behind Hydra on adopting Fedora 4, stuck on XACML until Drupal 8, which will break a lot of things and give opportunity for big change - if WAC offered at Fedora level, will probably adopt it in some form - at least a year away from doing anything
      4. another proposal: take Fedora 4 role-based model, use as basis for WAC, then put XACML on top of that for backwards compatibility
      5. Stefano: custom system to serve content to Fedora 4 - working on XACML policies - want access control on indexing (triplestore or Solr), which is maintained by separate app
         1. this is motivation for Hydra access controls: so can write filter queries, embed as RDFa in HTML, etc.
      6. Forum: Fedora Tech Call
4. Update on Works use-case synthesis
   1. Almost done - found a lot of overlap - will put doc on wiki this week
   2. Some points of difference will be complex (collections linking to files, objects linking to parts of other files, etc.) - will aim to support these as options, to allow simple implementations to ignore complexity

Action items

• Justin: reqs for AF8 versioning to be sent to hydra-tech
• All: provide feedback on PR for WAC, https://github.com/projecthydra/active_fedora/pull/500 by end of the week
• Andrew: add WAC discussion to Fedora tech calls (updates will be given on hydra tech calls)
• Karen, Esmé, Tom to finish use-case synthesis and add to wiki by end of the week
