Umlaut Technical Overview

To give you an overview of the technical architecture of umlaut, we will go through a typical Resolve request, identifying all the classes involved, and pointing to their api doc if possible.

OpenURLs are sent to the default index action of the resolve controller.

In the resolve controller, a before filter method called init_processing is run to parse the OpenURL and set up the Umlaut request (or retrieve an existing request).
