Notes

1. Introductions and Updates
   • University of Technology Sydney provided some details of their OCFL implementation
   • node.js with OCFL
   • data publications repo
   • GitHub
     • https://github.com/uts-eresearch/ocfl-js

   • Observations having worked with the OCFL specification
     • Guidance on storage paths would be helpful, i.e. 'extensions'
   • Mike would be willing to demo on a future call
2. S3 demo
   • ocfl-java
   • Peter W demonstrated creation and update of OCFL object in S3
     • Additionally, OCFL objects with large files and many files were demonstrated
   • AWS S3 has issues with eventual consistency and locking
     • Therefore, ocfl-java uses a local RDBMS for locking
   • Current inventory is cached in DB
   • DB is auto-populated, lazy-loading
   • Tool (ocfl-java) still in-progress
     • Performance issues around large files yet to be fully resolved
     • Currently no caching, all retrievals coming from S3
3. PASIG
