It's actually a mid-level concern for us :-) We generate a few metadata feeds
that are used by our services and which are not published service endpoints.

Ian's 2012 post describing UK federation metadata aggregation
(https://iay.org.uk/blog/2012/08/uk-federation-metadata-aggregation/) doesn't
describe these newer XML metadata feeds nor the experimental JSON discovery
feeds, so it's probably worthwhile if I write a short blog on that.

Alex
