While raw JSON does not include a link type, this needn't be a problem in
practice. For example, distlib already contains mechanisms which support
cross-references and references to external data, as per the example code in
[1]. I will shortly be adding to this a mechanism to integrate data in
external files in a standardised way.

The distlib code is an extension of the mechanisms already in the stdlib in
logging.config and used by dictConfig, which are documented at [2].
