UK Access Federation has already started rolling out SAML 2.0 Metadata with some MDUI information.
UK Access Federation is an excellent showcase for Discovery UIs, because of the huge amount of Providers.
I’ve added support for parsing the MDUI metadata extension to the DiscoJuice metadata server; and tested it against the metadata feed from UK Access Federation.
Right now, I’m consuming both logos and geo locations from metadata.
Here is how it looks:
To get the logos properly sized, and delivered quickly to the clients, the DiscoJuice metadata server is caching all the logos. It looks through available logos, and looks for the largest icon with a height in the range between 24 and 40 pixels, if present. If not, it takes the largest logo it finds, and resamples it to 38 pixels height, mainaining aspect ratio.
Notice: Very few of the entries includes geo location; and the IP based geo location fall-back is used. That does not work that well in UK since many of the providers are co-located on some kind of proxy.
If you’re interested in learning more about DiscoJuice in the UK, I’ll be speaking at FAM11 (Federated Access Management Conference) in London November 9th. Before then, I’m planning on doing a bunch of improvements to DiscoJuice. Stay tuned!
