Agenda:

  1. Call for agenda items
  2. Sufia bit rot: https://travis-ci.org/projecthydra/sufia/builds/67064987
    1. Someone should volunteer to track down the bug in rails 4.1 or we should stop supporting 4.1 (https://github.com/projecthydra/sufia/pull/1209)
    2. Our preference is to discontinue support for 4.1 via Justin's PR. (Mike has put out a call for comment on the tech list.)
  3. Curation Engine progress report
    1. Matt reports a major obstacle in the process of moving curation-engine functionality into sufia-core and curation-concerns: 40% of the tests are failing because associations are not implemented in Sufia's Hydra::Works and underlying PCDM layers, preventing PCDM objects from looking up the objects they belong to. If possible, will set these problems aside to continue work on curation-concerns, but it may not be possible.
  4. AF association/reflection code, its documentation and its impact on hydra-works
    1. Progress on the curation-concerns problems is hampered by the complexity and under-documentation of the relevant code in ActiveFedora, with several layers of indirection and levels of inheritance, all with undefined interfaces, inaccurately described specs, etc. To clean this up would be a major refactoring job. Mike suggested we look at this again after the ActiveFedora conclave coming up at Penn State next week, which may improve the documentation.
  5. OR synopsis
    1. Mike reported that Hydra was well-represented by the participants, though not as prominent on the program as in previous years. The new (and stunning) Hydra t-shirt was a hit. The Hydra-in-a-Box project got a lot of interest. Glen appreciated the developer track.
  6. https://github.com/ActiveTriples/linked-data-fragments summary?
    1. Trey reported that Oregon intends to use the new service (which will become a rails engine) to abstract away the Marmotta interface and provide a common interface for accessing and caching remote RDF resources
