Sprint Team

General

A. Soroka
- out sick
Eric James
- Running into problems that should be documented
  - Can update the config, but that doesn't change what's shown by the repo – need to refresh. Is there a simple way to refresh the repository?
  - Will add errors to the wiki
- Content changes show up in the repo, but browser doesn't find it reliably because of caching issues, will write IT to demonstrate this

- Clustering worked once firewall was relaxed to allow nodes to talk to each other
- Working through triplestore use cases
  - Most look like they are supported by what we have now
  - Will expand SPARQL Recipes to cover more of the use cases

Eric James
- Eclipse bugs yesterday, switching to IntelliJ. Trying to get IT to verify federated content updates when filesystem is updated.
- When changing repository.json and restarting repo, it's still using the old config.
  - Adam: Mode may be storing projection info in repository and not updating it for some reason.
A. Soroka
- We are running into the limitations of JCR content type system, may need to do something else (implement our own, adopt a different one)
- There are lots of interesting possibilities, but they aren't practical to implement quickly.
- SPARQL may be a better strategy: in a transaction, a user could create content, run SPARQL queries to validate, and then commit or rollback based on that validation. Could add a single-step process for doing that automatically.
- Will put on wiki/mailing list for feedback.
Unknown User (escowles@ucsd.edu)
- Finished reviewing triplestore use cases and found them well-supported. Updated SPARQL Recipes and RESTful HTTP API - Objects to demonstrate some functionality, like updating multiple objects with a single SPARQL Update, using more vocabularies, etc.
- Will investigate Mulgara-style recursion functionality. This is not available in standard SPARQL, but Jena and/or Sesame may have similar extensions.
  - Adam: May be able to get hierarchy from repo, and then build a simple SPARQL query.
- Will try to replicate Eric's federation config reloading issue.

Eric James
- Hit problems with Eclipse, switched to IntelliJ
- Having problems debugging federation config issues
  - Probably not productive to keep working on this
  - Will write up notes on federation and close the ticket
- Will move on to testing authzn on federated filesystems
  - Related to Research Data use case
Unknown User (escowles@ucsd.edu)
- Will update triplestore and large file uses cases
  - All of the triplestore use cases are satisfied by external triplestore or other repository functionality
  - File use cases are mostly satisfied, but some outstanding issues related to authzn.
    - Some use cases reference async functionality for HPSS, but that is waiting for Jersey upgrade
    - Testing large file ingest using REST API writing to federated fs, and copying large files between repo and federated filesystem.
Andrew Woods
- Getting up to speed on sprint activity, will cleanup Pivotal tickets today
- Will talk to David Wilcox about starting acceptance testing for triplestore and large file features
- Will try to replicate Eric's bugs with Modeshape not reloading federated filesystem configuration after restart
  - Will both in-place configuration with Jetty, and external configuration with Tomcat to try to tease out possible environment/runtime issues.
