Review of active fedora tutorials

https://github.com/projecthydra/active_fedora/wiki/Lesson%3A-Use-Rails-fields_for-helper-to-Create-Forms-that-Edit-Complex-Nested-RDF-Graphs

  • Comments by Adam on reviewing RDF metadata tutorial

    • There are 9 lessons. Did 5 with edits to the 5th, got stuck in the 6th and didn't try later lessons.

    • The tutorial is pretty good shape.

  • James - Used RDF tutorial and read through curate model and found that the tutorial was a good guide

  • Corey did similar tutorials to lessons 7, 8 and 9 and the lessons look fine

  • Note: Navigation at the end of 6 is broken in wiki

Does the tutorial do what we want? or what do we want the tutorial to cover?

Any other tutorial out there?

Action

Rough proposal to replace RDF with OM in dive into hydra at hydra camp curriculum

  • The goal of this is to

    • Make applications simple

    • Get people to base their schema on RDF rather than xml

    • Reduce the barrier to using RDF in Hydra

  • Is this necessary? Why do that?

    • After dive into Hydra, playing with metadata is complex and OM is just not friendly. Moving into RDF will lower the barrier - Jon

    • or shift the barrier

    • Corey - Technical barriers of OM versus RDF is not an issue. OM or RDF doesn't make a too much difference, except OM perpetuates using xml. There is a feeling in the community that RDF is better.

    • Mark - At the dive into Hydra level, it makes no diffence.

    • We need to bear in mind that the xml people are left out of this group.

    • Question on why is RDF is better than XML - What do we mean by interoperability of RDF?

      • Mike and Tom explain reusing RDF as not having self made xml nodes and be able to leverage the data btter through rdf graphs and query the data in a useful way.

    • Dive into Hydra should give a choice between RDF and XML and represent both to people

  • Should we ask the Hydra community if RDF should replace OM in Hydra camp?

    • Mark: I don't think the email is necessary. Just because Dive into Hydra includes RDF, doesn't mean we rule out XML

  • Need to provide more context in the tutorials, rather than just diving in and making a book model. t would be good to walk through the sufia model for example.

  • Do we need to expand that proposal. What work needs to be done for this?

    • RDF datastream needs to be added to active fedora

  • For an RDF based hydra curriculum what do we need?

    • We could swap the dive into Hydra tutorial with OM for RDF
