Keepingpreserving

Keepingpreserving is a term used to describe a set of practices designed to maintain essential properties of a system while it undergoes change. It emphasizes that change should not erode core guarantees such as correctness, reliability, or quality. The concept is used across disciplines, including software engineering, data governance, and cultural heritage, and can refer to both technical and organizational measures aimed at safeguarding foundational characteristics.

Core principles of keepingpreserving include maintaining invariants—conditions that must hold true for the system at all times—along with ensuring interface compatibility when components evolve. It also stresses traceability, so that requirements, design decisions, and outcomes can be linked, and the use of controlled change processes to minimize unintended effects.

Common techniques involve clear contracts or interfaces, regression and contract testing, versioning strategies, feature flags, and rollback or recovery plans. Auditing and provenance tracking help document what has been preserved and why, supporting accountability and long-term reliability.

Examples include maintaining API compatibility during software updates, preserving data quality and lineage in data pipelines, and safeguarding provenance and authenticity in archives during digitization. While keepingpreserving can enable safer evolution, it also introduces overhead and may require deliberate trade-offs between aggressiveness of change and strength of preservation.

Related concepts include invariants, backward compatibility, change management, and data governance, all of which inform practices aimed at balancing evolution with stability.
