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”?

Building an Institutional Repository Interface Using EJB3 and JBoss Seam

This tour is designed to show the overall architecture of a FEDORA digital object repository application within the JBoss Seam framework while at the same time pointing out individual design decisions and extension points that are specific to the Ohio Digital Resource Commons application. Geared towards software developers, a familiarity with Java Servlet programming is assumed, although not required. Knowledge of JBoss Seam, Hibernate/Java Persistence API, EJB3 and Java EE would be helpful but not required; brief explanations of core concepts of these technologies are included in this tour.

The tour is based on revision 709 of /drc/trunk and was last updated on 18-Jan-2007.

Picking a Java Web Application Framework

We’re beginning a new phase of our digital library development at OhioLINK and an oversimplification of one of the consequences of this new phase is that we will be developing more software from scratch rather than adapting stuff that we find out there on the net. (Another consequence of this new phase is our interest in applying the Service-Oriented Architecture paradigm to library applications.) In previous phases, we were somewhat at the mercy of whatever development framework was used in the application we were adopting. As we start this new development where we control more of our own destiny, we wanted to take a step back and look at the available frameworks to support our development efforts. The options we identified at the start were plain Java servlets, Apache Struts, Spring Framework, and EJB3 with JBoss SEAM.
