Minutes

Open Repository coming up in June

AIC has started implementing Fedora4. There is a chance that they will present their plans and reports remotely.

XACML attributes

• Greg & Eric are working on XACML
• Interface is ready to implement
• Policies are retrieved from repo: auth request -> modeshape delegate -> XACML request
• Policy objects can be anywhere
• Policies can be grouped in policy sets, retrieved by UID
• Hydra IDs/metadata can be translated into roles via sequencers
• SPARQL/RDF is best way to store and retrieve
  • Attributes are find by querying by predicate - likely no extra configuration is needed
  • Attributes are collected to make pieces of auth logic, e.g. embargo date attribute can be used to validate access before/after a certain time/date
• Andrew: Auth rules are not honored in triplestore or Solr index. We need to support that. 
  • Greg: There is some design
  • Esme: As far as you index in Solr correctly you can configure Solr to do that by mapping roles to Solr entities
• Andrew: is the XACML engine external and is it deployed as separate process?
  • Greg: it will be internal at first, externalizing it needs lot of plumbing
  • Andrew: another concern is performance, but if it's not bad it's better to keep the XACML engine external in order to keep the Fedora core codebase clean
  • Greg: maybe as a second pass
  • Initial draft implementation will be in next sprint

LDCX report

• un-conference and forum for technologies for library archives focused on Hydra, Blacklight, Fedora, IIIF
• Andrew and Esme were present

• Hydra
  • Strong Hydra community
  • Was pointed out that the F4/Hydra connector needs more resources and more focus
  • 25 developers participated to hackfest
  • Good engagement, some new faces
  • Sufia, ActiveFedora 8, Fedora Lens are the main Hydra stack elements
  • Focus on mapping RDF to addressable properties
  • Focused on having a demo which can be a model for other developers to build upon

• IIIF
  • Might possibly integrate with Fedora
  • K. Clarke has done some work in that direction
  • Integration point would be hat IIIF server accesses Fedora server to get images
  • Kevin: Sequencers can be involved
  • NWU heavily relies on disseminators for images, could be a good use case
  • AIC also uses pyramidal images with IIP, want to automate PTIFF generation and retrieval through Fedora

• ResourceSync
  • 21st CEntury's OAI/PMH for sharing metadata across repositories
  • Based on Google Sitemaps
  • We already have sitemap feature in F4 but Fedora might not use the same machinery
  • There could be an implementation of rsync for F4
