[Yaml-core] yaml:// (also jsync://)

[Trans <tra...@gm...>]

I was thinking that it might be cool to have a REST specification for
accessing the data within YAML files.

  yaml://some.domain.com/example.yml/<ypath>

The syntax for the <ypath> portion of the URL would need working out,
but I think this could be very useful for embedding information in
other documents.

I imagine the same could apply to a jsync://, and that might be able
to get a faster footing since it is simply JSON.

Thoughts?
