I've made a new version of the URI redirection engine that runs in Django (see the original post here). The tool allows you to provide a list of URI patterns that identify specific resources, and redirect traffic that matches that pattern to a URL where a representation of the resource exists. It allows for content-negotiation, and the new version also begins to build infrastructure by which various instances of the application can communicate with each other.

Each instance of the application is informed about the existence of various registers, which are essentially sets of URIs. The application may or may not know how to resolve URIs that are a part of any given register, but can send incoming requests to others servers capable of resolving that register's URIs.

Here are a few screenshots to give a taste of what it is like to use our new Django app to manage a set of URI redirections:

Administration Overview:

For any URI-Scheme: Basically, the Django app allows you to control a listing of MIME Media Types, and Rewrite rules.

USGIN URI-Scheme: The same basic structure, but the USGIN-specific app allows you to control a listing of Name Authorities and Resource Types, as described in this post.

Listing of Rewrite Rules: A nice overview of what rewrite rules you have in place, and a mechanism for searching for the one you might need to adjust.

Creation of a Rewrite Rule:
