Brief History
Islandora started as an in house project as a front-end for Drupal 5 and Fedora 2.
Drupal was to be one of many frontends for Fedora, we talked about using Moodle, OCS, OJS and other open source PHP applications.
Early on ● Limited Drupal
specific code in favour of pure PHP
● Mapped callbacks in ISLANDORACM xml stream.
Drupal 7
As time went on we realized we could not realistically support more than one frontend and Drupal was the only one we were really using.● So we leveraged as much Drupal Code and
as many Drupal principles as made sense (hooks, alters, menus etc.)
Drupal 8Fairly extensive rewrite of Drupal.Includes:● Integration with Symfony2● Use of Twig for templating (by the creators of Symfony)● Using YAML for configs (instead of the database)● More RESTful● HTML5● Views in core
Drupal 8 - Symfony2Symfony is a PHP web application framework
The move to Symfony will require some changes to modules.● Hooks will mostly wrap Symfony concepts (like events)● Modern OOP approach● hook_menu will use Symfony routing● PSR (coding standards and conventions, namespaces
etc.)● Composer (Dependency Manager)
Drupal 8 - ThemesNew Template engine called Twig● Twig is fast● Twig has good IDE support● Twig is more secure● Twig is easy to useNew layout system● Site builders define layout (instead of
themers)
Drupal 8 - configuration
● Info file is now YAML● Module configuration can now be stored in
YAML files (much better for developing, testing, deploying)
● YAML is human readable and machine parsable (allows comments as well)
● Standard (not Drupal specific)
Drupal 8 - REST● No longer assumes every request is for a complete
page.● Easier to expose content in different formats (json, xml
or something else)● Easier/better communications between systems● Easier to make custom mobile apps
More info
Drupal 8 - IslandoraSimilar to the move to Drupal 7 we will probably wait for the dust to settle a little before we spend too much time on Drupal 8. We’ll have to wait for required modules to be released etc.
Islandora on Drupal 8 may only support Fedora 4?
Drupal 8 Release Cycle
Fedora and Islandora
Fedora had some changes between version 2 and 3, but they were not that significant.● Changes in package names required the Drupal filter to
be updated
● Fedora 3 brought in the CMA (content model architecture) but we were already simulating a lot of that with our ISLANDORACM stream in Fedora 2.
Fedora 4
Fedora 4 is basically a rewrite that allows Fedora to leverage Modeshape and it’s underlying dependencies like Infinispan.
Modeshape has several rest apis include JSR-283 and it’s own Modeshape api.
Goals for Fedora 4According to the wiki link above the main goals for Fedora 4 are:● improved performance, enhanced vertical and
horizontal scalability● more flexible storage options● features to accommodate research data management● better capabilities for participating in the world of linked
open data ● an improved platform for developers—one that is easier
to work with and which will attract a larger core of developers.
Fedora 4 vs Fedora 3Fedora 4 will provide:● Clustering (Boston hackfest)● Projecting over existing data sources (link)● Oauth support (more info)● Fedora 4 can be configured to retain multiple
copies of binary content. (more)● New REST API more
Islandora and Fedora 4
● DiscoveryGarden has a developer working part time with the Fedora Futures project.
● UPEI was involved with some early sprints● We hope to have a beta Islandora release
soon after the Fedora 4 beta release.● Duraspace wiki
Challenges for Islandora● Security
○ Drupal servlet filter (currently extends Fedora3.x code)○ XACML (will it exist? will the vocabulary be the same?)
● Discovery○ Islandora uses ITQL and SPARQL for generating collection views of
objects. These will all have to be converted to using SPARQL. Triplestore will probably live outside of Fedora 4
○ Indexing in Solr (no gsearch for Fedora 4)
● Transactions (add support in islandora)
see the wiki for more details
Fedora 4 Current Status
Notes on Wiki
You can help, I believe they are looking for people to testing of Fedora 3 to Fedora 4 migrations etc.
