How to get the package metadata as structured data?

[Philippe Ombredanne]

Is there a way to get all the package metadata as pure
data beside the html page [1] or the Guile sources [2]?
Like some JSON of sorts or similar?

That would be somewhat needed to audit the licenses
asserted in the metadata and compare them with actually
detected licenses.
