The oEmbed protocol is used by a number of sites to make it easier to get
thumbnail images or inline video player code for a foreign-hosted media entry
that we've just got a URL for. We use this in StatusNet to fetch previews and
video embedding for remote media.

Spec: http://oembed.com/

oEmbed data can be read via JSON or XML formats; this may be a good candidate
for a custom API module like the opensearch suggestions.


Note that there's an oEmbed proxy service which provides basic metadata on
articles for Wikipedia:
http://oohembed.com/oohembed/?url=http%3A//en.wikipedia.org/wiki/Bridge

but it does a poor job on images, where it's really more important:
http://oohembed.com/oohembed/?url=http://en.wikipedia.org/wiki/File:Akashi-kaikyo_bridge3.jpg

We should be able to expose most files as 'photo' or 'video' types, which lets
us include a thumbnail URL, and inline HTML for Ogg video players etc.

Compare with Flickr and YouTube entries:
*
http://www.flickr.com/services/oembed?url=http://www.flickr.com/photos/brionv/4936308232/&format=json
*
http://www.youtube.com/oembed?url=http://www.youtube.com/watch?v=1tjC0mYfcrg&format=json

There are also optional 'maxwidth' and 'maxheight' parameters, which can be
used to specify what size thumbnail or inline image/video player you want; the
resulting photo/thumb URL or HTML should match.

<link rel>s can specify the JSON and/or XML discovery URLs for the item on the
current page, and should be provided to third-party services will pick it up.

I _think_ we should be able to make the video handling pretty general by
grabbing HTML fragments from the media handler, though I'm not 100% sure.
