Comment 3 for bug 650967

On second thought, I don't think "contents" is the right relationship for that last example. It implies that language-page is the "table of contents" for the language resource type itself, not for specific language entries. I think we'd have to come up with something new, define it in a metadata file, and link to that metadata file in the 'profile' attribute.

So you'd still have something Launchpad-specific (the semantics of this new relationship), but it would be somewhat standardized. Or we could go with the JSONPath thing we have now.
