Notes

Housekeeping
- Need volunteer to record decisions and action items.
  - James
- New agenda items?
  - Esme - Example with new branch?
    - Best example is Oregon digital gist - working on reworking into AF gist and rewriting tutorial
- Review of outstanding action items.
  - Tame your RDF Metadata - (Esme, Adam, Mark ?)
    - No update
  - AF::Rdf documentation - (Tom Johnson, In Progress for March 23rd.)
    - Will be complete in advance of Code4Lib
Tom meeting with Tech Transfer people about CLA compliance document prior to iCLA signature - next day or two
- Looking for feedback after pull request is submitted
Rights Metadata
- Hydra rights metadata in RDF
- Motivation/Goals?
  - Interested in consolidating on RDF for coherent graphs for all object properties, including permissions
- Next Steps?
  - Working group and Hydra-Tech should examine Mike Giarlo's Gist for future discussion: https://gist.github.com/mjgiarlo/7096160
RDF List
- Limitation in RDF.rb implementation.
  - Can't use fully qualified URLs as head nodes - requires blank nodes, which causes problems with objects which are lists
  - Challenging to identify the URI of the head node - need to avoid empty lists
- General issues with ordered lists in RDF.
  - Linked list implementation - challenging to query; consensus that there are challenges with ordered lists in RDF
- Use Cases/Use in MADS & MODS. (UCSD?)
  - UCSD uses both blank nodes and fully qualified URIs as head nodes of lists
- Ordered List Ontology as alternative?
  - Easier to query - numerically ordered
- Need advice on RDF Lists for the community - RDF list in existing code base is tempting, but obstacles should be made clear - Tom Johnson will write AF tutorial on RDF lists by the end of March
Code4Lib
- In-Person Lunchtime Meeting Agenda
  - Event falls on March 25 - RDF WG call will be cancelled
  - Tom Johnson will assemble agenda - ideas?
    - Fedora 4 Hydra support discussion and status?
- AF::Rdf Breakout
- Start defining migration paths to RDF
