HAL - Hypertext Application Language

A lean hypermedia type

HAL is a simple way of linking with JSON or XML.

It provides a small set of conventions on top of JSON and XML for expressing hyperlinks to, and embeddedness of, related resources.

The spec is here: hal_specification.md.

For a friendlier, more pracitcal introduction to HAL you can read this article: JSON Linking with HAL.

The JSON variant of HAL (application/hal+json) has now been published as an internet draft: draft-kelly-json-hal.
