  1. Object/Datastream Delete model
     
     • Mark as delete with state flag (PUT)
     • Purge (DELETE)

Minutes

Fedora 3.7

1. Scott to test Windows and Oracle

Ontology / Triplestore

1. Updating URIs to be web accessible
2. Adding triplestore with indexing service
   
   • Be able to make sparql queries similar to RI
   • Goal to allow triplestore pluggability
3. Will be using events to update index
4. Will also have an on-demand indexing capability
5. No longer a distinction between rels-ext and rels-int
6. New namespaces
   
   • repository: http://fcrepo.org/repository#
   • rest-api: http://fcrepo.org/repository/rest-api#
   • relations: http://fcrepo.org/repository/relations#
7. Is there a new predicate for parent/child relationships?
   
   • yes, in repository# namespace
8. Is there a legacy functional distinction between relsext/int that may be lost?
   
   • maybe not, will need to see from users
9. Request to get examples of current sparql queries
   
   1. Action: Scott, Jonathan, Adam (Mike D.), Greg
   2. Action: Esme to send out email requesting this input
10. Good experiences with Sesame
    
    • Fuseki is also an option
11. Suggestion to use 3.x ontology as start, to limit surprise
12. Would like to be able to specify properties to be indexed in triplestore
    
    • e.g. Checksum for datastream wanted in update message
13. Approach is to make messages clean/simple
    
    • Have message consumer request back into the repo for additional properties
    • Note, if there are x number of consumers, there will be x number of calls into the repo
      
      • This issue is likely resolvable with broker configuration
14. It is fairly simple to create a new Message Producer
15. Are all jcr properties contained in responses
    
    1. Action: investigate arbitrary properties in RDF responses

General

1. Call for OAI-PMH participation
2. Call for async-storage REST API participation
3. AuthN/Z links have been added to wiki
   
   • Interest in spring security in populating context with principals
   • Spring security SAML also something to consider
4. To what extent would we want to include SAML?

Actions

•  Scott Prater to add example RI queries to wiki
•  Jonathan Green to add example RI queries to wiki
•  A. Soroka and Michael Durbin to add example RI queries to wiki
•  Greg Jansen to add example RI queries to wiki
•  Unknown User (escowles@ucsd.edu) to send email requesting RI query examples, RDF schema examples, etc be added to wiki
•  Andrew Woods to investigate F4 RDF responses and if arbitrary properties are included
