Discussion items

  • RDF 2.0 - order of the objects in triples is now truly random and no longer faux-preserved
Sufia/CC merger - Carrick has been on the calls with the arch. group, so he's probably been filling you in on that
PCDM - 2.0 may not happen
   Fedora performance - we're looking at switching the direction of memberships to make Fedora faster


PCDM 2.0 may not happen
recent discussion between islandora and hydra camps on IRC, islandora people wanted to fork 2.0 bc hydra people aren't receptive to their needs
Stefano Cossu discussion - want to move those around and have them as other objects?
Having the technical metadata as part of this fileset with object not a problem; becomes a problem when you try to index that
Not a blocking issue, just have to add some work into this
Our hanging MODS off off the object directly is an islandora thing -- to do what Hydra wants to do, we'd put that into a fileset
Describes predicate would be pointing to the object itself -- Esme Cowles is the person to contact for this (he wrote the PCDM 2.0 spec -- there are other people who've had this same use case)
Adam suggests treating it as a binary -- putting in a fileset (fits runs) - you've be able to do things like generate a checksum
The fileset idea is the representation of one original binary (so the original idea would contain the derivatives as well)-- Julie says that these technically are three different binaries we're getting from MDPI
In filesets - custom predicates (you can identify the different pres/prod/access) to define the different filesets
Julie: prob don't want to make fileheader changes on received files; Adam: not modifying original file, it's an ldp thing -- http head response --
Sufia/CC merger
document prior to HydraConnect to outline all of the decisions
much of Sufia can go back into Curation Concerns; other things: flippable features that can be turned on and off
This is being driven by Hydra in a Box work from Stanford
