This is an overview of metadata services available from broadcasters. The feeds referred to here contain radio and television data.

The Channel 4 API uses similar concepts to Radioconnected: Atom feeds, interlinking, standards-based.
They use no external standards, only Atom.
The information architecture allows access using A-Z, categories, brands (such as Hollyoaks), and EPG access.
Metadata for all Channel 4 programmes ever broadcast are available from this API, including links to the website and 4 on Demand.
The BBC maintains various metadata services. The simplest to access is http://www.bbc.co.uk/programmes/developers
This allows access to the BBC metadata in JSON, XML, and RDF.
This gives a wide variety of formats for developers but is not standards-based beyond the use of XML etc.
In additon the BBC offers a B2B Atom feed which in some cases contains more detail than the /programmes service. This makes use of Media RSS as well as Atom.
Metabroadcast offer a service named Atlas which aggregates metadata from UK broadcasters into a single feed, which is then supplied in JSON format.
The choice of JSON was to make adoption easier. Their data model has become quite complex however.
