A CAMARA meta-release is the way CAMARA brings its APIs to market.

A meta-release consists of a set of public versions of curated APIs that went though the CAMARA meta-release process.

The purpose of this document is to define

  • the milestones of the meta-release (this page), and the supporting Meta-release Process documentation
  • the activities expected from the different teams to move from one milestone to the next
  • the way to report progress on the meta-release itself, on the Commonalities and ICM releases and on API releases

For the schedule and content of actual planned meta-releases, see CAMARA meta-releases.

Meta-release milestones

Meta-release milestones and their associated actions are used to progress and track the status of the meta-release. 

  • A meta-release has 6 milestones, M0 through M6 described below. 
  • For the typical milestone dates of a meta-release, please see the Meta-release Process.

The following table lists the meta-release milestones, and includes a high level view of the activities expected from the various teams to reach these milestones. 

More details on these for each team are documented here:
