  1. Islandora Sync Bringing Drupal and Fedora closer 2013 - DLF

    Forum : Austin, Texas Kristian Allen Programmer - UCLA Digital Library
  2. Discussion Outline • UCLA Digital Library transition to Islandora Overview

    of shift to Islandora within UCLA DL • Digital Library community development options • Islandora Sync details Why the need? What does it do? • Questions
  3. UCLA Digital Library Snapshot • 250 Digital Collections • 1.8MM+

    Digital Asset Files • 20MM+ Metadata database records • 35TB+ Disk storage
  4. Growing Pains • Current system Locally Developed: Java EE /

    Struts 1.02 Oracle Database, Search and Persistence frameworks JBoss on Windows • Challenges Domain specific knowledge needed for development Proprietary software limits ability to leverage the community Bolting on partial solutions can become problematic
  5. The Community to the Rescue • Blacklight / Hydra Ruby

    / Rails • Islandora PHP / Drupal • Common Platforms Apache Solr for search and discovery Fedora Commons for repository and storage
  6. The Appeal of Drupal • Instant access to “lego block”

    code Thousands of modules help reduce development time Lower barrier to entry to encourage participation • UCLA Library move to Drupal CMS shift to Drupal within UCLA Library increases local expertise • Trend towards Drupal on campus Shift from Plone to Drupal in other departments
  7. Islandora Development • The Islandora Way != The Drupal Way

    Assets and metadata stored only in Fedora repository Limits which Drupal modules can be used out of the box • Leveraging the Drupal community Harnessing the collective power of Drupal ecosystem is limited • Option: Make Islandora more Drupal-ish? Yep, we sure can!
  8. Islandora Sync • Joint project with Discovery Garden • Goal

    to mask Fedora data as Drupal data • Fully open source on GitHub
  9. Core Features • Ability to map Drupal Content Types to

    Fedora Content Models • Map Drupal Fields to Fedora Datastreams or metadata elements • Replicate Fedora RELS-EXT references with Drupal Relation entities
  10. Fedora Repo Islandora Data Entry Forms Native Drupal Entities Islandora

    Sync Workflow Islandora Modules Drupal Modules 1) User updates an Islandora object, saves data to Fedora 2) With Islandora Sync enabled, hooks are fired to populate native Drupal entities with Fedora data Views Services Gallery Gmap Basic Image Large Image Book PDF Audio Video
  11. First iteration, be aware... • Works for UCLA DL workflow

    The UCLA Digital Library is the gatekeeper for our Fedora instance Changes via processes outside of Islandora might not be sync’d • One way sync Initial use cases placed most weight on Fedora to Drupal direction Hooks in place for Drupal push to Fedora • Scalability Still need to tweak Drupal for performance for large imports
  12. Islandora Data Access Options • Access to Solr index •

    Access to Fedora REST API • Access via Services Module via Sync Additional benefit of Drupal security options
  13. Where we hope to go • Foster increased community development

    By lowering barrier, we hope to encourage increased development • Continued improvement of core code Goal to contribute regular development to support roll into Islandora core • Increased Drupal Features packages MODS image mapping example is available now
