UK federation Metadata Aggregation

diagram full of boxes and arrows

One of the systems I work on is the back end of the UK federation's metadata system. Although I've talked about this in several presentations, the bare structural diagram isn't very informative on its own. Here, I present a snapshot of the architecture, and go into a lot more depth on the what, how and why than you'd get from just the slide on its own (click on the image to get a larger version).

I hope that this article can perform double duty as a case study for the Shibboleth metadata aggregator tool, which acts as the engine behind the metadata system and to which I also contribute as a developer.
