HTTP Discovery

HTTP Discovery Taking Resource URI and finding metadata

Requirements:
 * Should be able to get the metadata without accessing the resource.
 * You don't know what it is yet, so you shouldn't be interact with it yet.
 * The the resource can point at its metadata.
 * Must be accessible to different levels of developers.
 * Can't *just* require headers. Must also support an HTML solution.
 * Must work with web architecture.
 * Must be friendly to little and big players.
 * The same solution for your blog should work for a large company.

Background for the following table is at Eran Hammer-Lahav's blog post.

A combination of 1, 4 and 10 seem promising.

For dynamic mapping:

a. DNS

b. Known Location (like /robots.txt)

b is the /site-meta proposal.
