Disseminators As the Core of an Object Repository

I’ve been working to get JBoss Seam tied into Fedora, and along the way thought it would be wise to stop and document a core concept of this integration: the centrality of Fedora Disseminators in the the design of the Ohio Digital Resource Commons. Although there is nothing specific to JBoss Seam (a Java Enterprise Edition application framework) in these concepts, making an object “render itself” does make the Seam-based interface application easier to code and understand. A disseminator-centric architecture also allows us to put our code investment where it matters the most — in the repository framework — and exploit that investment in many places. So what does it mean to have a disseminator-centric architecture and have objects “render themselves”?

Fedora Disseminators to Enable Accessible Repository Content

Calling all accessibility technology experts! What follows is a line of thinking about using characteristics of the FEDORA digital object repository to enable access to content through non-graphical interfaces. Thanks to Linda Newman from the University of Cincinnati and others on the Friday morning DRC Developers conference call for triggering this line of thinking.

In a recent post defining universal disseminators for every object in our repository (if the last dozen words didn’t make sense, please read the linked article and come back), I hinted at having an auditory derivative of each object, at least at the preview level. During today’s conference call, Linda asked if such a disseminator could be used to offer different access points for non-GUI users. Well, why not? Let’s look back at the “presentation” part of the disseminator label:

Thinking about Our Fedora Disseminators

Another reason to consider the FEDORA digital object repository system, if having the ability to put all of your content in one place and reducing the complexity of digital preservation aren’t enough, is the capability to create and define behaviors that the content can perform. In the FEDORA world, these behaviors are called disseminators.
