Minutes
Fedora 3.7
- Scott to test Windows and Oracle
Ontology / Triplestore
- Updating URIs to be web accessible
- Adding triplestore with indexing service
- Be able to make sparql queries similar to RI
- Goal to allow triplestore pluggability
- Will be using events to update index
- Will also have an on-demand indexing capability
- No longer a distinction between rels-ext and rels-int
- New namespaces
- repository: http://fcrepo.org/repository#
- rest-api: http://fcrepo.org/repository/rest-api#
- relations: http://fcrepo.org/repository/relations#
- Is there a new predicate for parent/child relationships?
- yes, in repository# namespace
- Is there a legacy functional distinction between relsext/int that may be lost?
- maybe not, will need to see from users
- Request to get examples of current sparql queries
- Action: Scott, Jonathan, Adam (Mike D.), Greg
- Action: Esme to send out email requesting this input
- Good experiences with Sesame
- Fuseki is also an option
- Suggestion to use 3.x ontology as start, to limit surprise
- Would like to be able to specify properties to be indexed in triplestore
- e.g. Checksum for datastream wanted in update message
- 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
- It is fairly simple to create a new Message Producer
- Are all jcr properties contained in responses
- Action: investigate arbitrary properties in RDF responses
General
- Call for OAI-PMH participation
- Call for async-storage REST API participation
- AuthN/Z links have been added to wiki
- Interest in spring security in populating context with principals
- Spring security SAML also something to consider
- 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
Yes, arbitrary properties are included in the RDF responses of requests on objects (See email in ff-tech: "Custom Properties in Responses")
