What's a link?

When you ask a developer, what is a “link”, they may quickly answer “a URL” or “a URI”, but this is not the whole truth. A URL is only an address that you can find to build a resource. A “link” connects one resource to another. My goal is to create a PHP interface that describes the abstract data-model behind a link. To do this job correctly, I felt I had to dig through all the relevant hypermedia

HALは便利そうだけど、JSONSchema臭するよね。
