OpenProxy Specification

The key words “MUST”, “MUST NOT”, “REQUIRED”, “SHALL”, “SHALL NOT”, “SHOULD”, “SHOULD NOT”, “RECOMMENDED”, “NOT RECOMMENDED”, “MAY”, and “OPTIONAL” in this document are to be interpreted as described in BCP 14 [RFC2119] [RFC8174] when, and only when, they appear in all capitals, as shown here.

Definitions

Media Types

Media type definitions are spread across several resources. The media type definitions SHOULD be in compliance with [RFC6838].

Some examples of possible media type definitions:

  text/plain; charset=utf-8
  application/json
  application/vnd.github+json
  application/vnd.github.v3+json
  application/vnd.github.v3.raw+json
  application/vnd.github.v3.text+json
  application/vnd.github.v3.html+json
  application/vnd.github.v3.full+json
  application/vnd.github.v3.diff
  application/vnd.github.v3.patch

Specification

Versions

The OpenProxy Specification is versioned using a major.minor.patch versioning scheme. The major.minor portion of the version string (for example 3.1) SHALL designate the OPS feature set. .patch versions address errors in, or provide clarifications to, this document, not the feature set. Tooling which supports OPS 1.0 SHOULD be compatible with all OPS 1.0.* versions. The patch version SHOULD NOT be considered by tooling, making no distinction between 1.1.0 and 1.1.1 for example.

Occasionally, non-backwards compatible changes may be made in minor versions of the OPS where impact is believed to be low relative to the benefit provided.

An OpenProxy document compatible with OPS 1.*.* contains a required versin field which designates the version of the OPS that it uses.
