Community Registry

To minimize the barriers to using Fedora, a free, open source application, there is no required "registration" process. However, it is extremely beneficial to the broader Fedora community if we collectively aggregate some minimal details describing our respective repository installations.

DuraSpace maintains a registry [7] of installations that is populated on a voluntary basis. The 4.4.0 release raises the visibility of that registry, and hopefully the likelihood that repository managers will self-register [8] in it, by adding a link on the Fedora installation spash-page requesting exactly that.

Upgrading and Migrating

A primary focus of the ongoing Fedora effort is to facilitate the upgrade/migration of Fedora3 repositories to Fedora4. To this end, a couple of improvements have been incorporated into the "migration-utils [12]" upgration utility.

...

External Services

One of the exciting capabilities that Fedora enables is the creation of distributed, asynchronous, message-driven services that are external to the core repository but are triggered by repository events. This release further improves the deployment and runtime configurability of the Fedora-related Apache Camel-based [13] features. 

Web Access Control

A significant community success that is found in this release is an initial implementation of an Web Access Control [14] authorization module. This authorization module enables the establishment of access policies modeled as linked data. This feature was initiated, planned, designed, and implemented by a group of community stakeholders.
