Resolving Relative URLs

[dillonredding]

I'd like to clarify exactly how to resolve relative URLs in a Siren representation. I believe we can simply follow the rules from Section 5.2 of RFC 3986, which makes this more a problem of establishing a base URL. Here are my thoughts on the few spots to consider:

• hrefs in the top-level links and actions
  • Base URI is the one used to retrieve the entity (see Section 5.1.3 of RFC 3986).
• hrefs in sub-entities (including their links and actions)
  • Recursively check encapsulating entities' self links for an absolute href. If one exists, use that as the base URI. See Section 5.1.2 of RFC 3986.
  • Otherwise, the base URI is the one used to retrieve the top-level entity.
