On: No JSON/MAPS interoperability in 17.0?

[icebraining]

I'd copy it from the RDF world:

  {
    'author': {
      'name': 'Jack',
      'homepage': <http://jackshome.com/>,
    }
  }

As for the use case, the easiest to conceive is JSON-reading search engines. Think about what we could do with all that structured data ;)
