===== Discussion =====

A Version Control System performs [[dido:99_annexes:annex-b-terms-and-definitions:v:version_control|Version Control]] for one or more [[dido:99_annexes:annex-b-terms-and-definitions:a:artifact|Artifacts]].

The system records distinct Artifact revisions and preserves the relationships among them.

A Version Control System allows an authorized user or process to:

  * Add an Artifact to Version Control
  * Assign an identifiable revision
  * Retrieve an identified revision
  * Distinguish one revision from another
  * Record a relationship between revisions
  * Compare revisions
  * Record changes to an Artifact
  * Restore or reuse an identified revision

A Version Control System may manage:

  * Source code
  * Configuration files
  * [[dido:99_annexes:annex-b-terms-and-definitions:i:infrastructure_configuration|Infrastructure Configurations]]
  * [[dido:99_annexes:annex-b-terms-and-definitions:i:infrastructure_blueprint|Infrastructure Blueprints]]
  * Models
  * Schemas
  * Scripts
  * Policy files
  * Build specifications
  * Documentation

A Version Control System differs from Version Control:

  * [[dido:99_annexes:annex-b-terms-and-definitions:v:version_control|Version Control]] is the process for managing revisions
  * A Version Control System is a system that performs that process

A Version Control System may include a repository, revision identification, comparison, branching, merging, access control, and retrieval capabilities. The presence or use of any particular capability depends on the applicable requirements.

===== Definition =====

//system that performs version control by recording identifiable revisions of artifacts and preserving the relationships among those revisions//

===== Note =====

A Version Control System does not by itself establish that a revision is approved, released, deployed, authoritative, or subject to a specified retention period.

A Version Control System may record information such as:

  * Revision identifier
  * Preceding revision
  * Succeeding revision
  * Change author
  * Change timestamp
  * Change description
  * Repository location

The applicable requirements determine which information the system must preserve.

The term does not require a particular product, repository architecture, branching model, merge model, storage technology, or deployment method.

===== Example =====

A Version Control System assigns an identifiable revision to an [[dido:99_annexes:annex-b-terms-and-definitions:i:infrastructure_configuration|Infrastructure Configuration]], records its relationship to the preceding revision, and permits an authorized deployment workflow to retrieve it.
