The YAML format is intended for human interaction. Scripts also want to consume this data, so we'd like to publish a machine-friendly format for them. That format adds a version and a sha, so that people have a way to trace the published data back to its source, as well as forward and reverse mappings built from the data to simplify the questions consumers will wind up querying from the data.

This repo contains the spec, and the specs are used against data in

gating jobs to validate consistency. However, the specs use URIs to

refer to each other for external consumption, which makes gating

changes tricky. Instead of fetching from the already published spec,

use the local one so that changes can be self-gating.
