====== Baseline Composition ====== [[dido:99_annexes:annex-b-terms-and-definitions:start|Go up to Terms and Definitions]] ===== Discussion ===== Baseline Composition combines two or more controlled [[dido:99_annexes:annex-b-terms-and-definitions:b:baseline|Baselines]] or baseline elements into a defined configuration for a build, deployment, assessment, or operational purpose. The composition identifies the participating baselines, their resolved revisions, their relationships, applicable precedence rules, and any compatibility constraints. Within Crucible, Baseline Composition may combine an [[dido:99_annexes:annex-b-terms-and-definitions:i:image_baseline|Image Baseline]], [[dido:99_annexes:annex-b-terms-and-definitions:i:infrastructure_baseline|Infrastructure Baseline]], provisioning source, application source, and [[dido:99_annexes:annex-b-terms-and-definitions:c:compliance_baseline|Compliance Baseline]] within a controlled pipeline workspace. Baseline Composition allows the participating baselines to evolve independently while preserving an explicit record of the versions selected for a particular result. ===== Definition ===== //combination of two or more controlled [[dido:99_annexes:annex-b-terms-and-definitions:b:baseline|baselines]] or baseline elements into a defined configuration for a build, deployment, assessment, or operational purpose// ===== Source ===== Generalized from configuration management, systems integration, software composition, and baseline-management usage and specialized for the Crucible architecture and operational model. ===== Note ===== Baseline Composition does not merge the identities of the participating baselines. Each Baseline retains its identity, revision history, and change authority. A composition may contain only image or infrastructure baselines and need not include application source. ===== Example ===== A Crucible Description composes a hardened [[dido:99_annexes:annex-b-terms-and-definitions:r:rhel]] 9 Image Baseline, a Kubernetes Infrastructure Baseline, a STIG Compliance Baseline, and an application repository into the configuration used for a deployment. ---- © 2026 Dido Solutions, Inc. and Jackrabbit Consulting, Inc.
