Machine tagging the ³ÉÈËÂÛ̳
I'd like to propose an experiment. If you ever publish a photograph on Flickr that features, or is otherwise related to, a ³ÉÈËÂÛ̳ TV or radio programme you might think about machine tagging it with the programme's unique identifier. First find the programme's unique PID (that's the 8 character ID you find in /programmes or iPlayer URLs; the "b00lj1nc" in /programmes/b00lj1nc), then add a Flickr tag that looks like this...
bbc:programme=b00lj1nc
That's it, the photo is now machine tagged. Machines can now discover that refers to this programme. This is a rather trivial example; my radio tuned to Any Questions on ³ÉÈËÂÛ̳ Radio 4. If you click through and check the tags on Flickr you'll see something that looks like the machine tag above.
