Minutes

OAI Provider Predicates Prototype

• frank asseg was not on the call to discuss. 
• Will move the discussion to next week.

Database connector

• Proposed by Stefano Cossu and Nikhil Trivedi
• Need to make a database available to view as nodes in Fedora
• Similar to ModeShape metadata connector
• Need to whitelist tables to make available
• Map fields to node properties
• Make data available
• Need to create Fedora-specific nodes similar to file system federation
• Seems like it would be generally useful to the community

F4 -> F4 Federation

• Proposed by Stefano Cossu
• Mirror particular content from one Fedora node to another
• Use case: public Fedora mirror that only contains publicly available nodes (indicated with mixin)
• ModeShape or JCR connector?
  • JCR-level might be more efficient
• Greg Jansen: Maybe filter via access controls rather than federation?
• Stefano Cossu: Need 2 Fedoras for load balancing and a public mirror outside the DMZ for security reasons
• Michael Durbin: Federation layer is somewhat dumb. Difficult to emulate all repository functions between source and target
• Greg Jansen: Probably easier to express security in a declarative way in one repository through XACML or something similar rather than running 2 nodes and trying to manage security via Federation
• Stefano Cossu will work on this and report back

Packer/Docker/Puppet for Graphite server?

• Packer script to generate a VM image?
• Docker, Puppet, etc.?
• Greg Jansen: Using Packer to make dev VMs on local machines

Handling Blank Nodes

• Raised by Stefano Cossu
• Blank nodes seem to be  somewhat supported in the latest build
• Not sure if this comes from Fedora development or ModeShape?
• No one on the call is familiar

Defining Order of Nodes in a Hierarchy

• JCR has convention, ModeShape has an API, Fedora does not

• Any thoughts on this?

• Michael Durbin: Would like this a lot. Incompatible with RDF?

• Stefano Cossu: Define with LDP properties?

• Greg Jansen will add more detailed notes
