custodianwhich

Custodianwhich is a term used in discussions of data governance to describe a decision-support framework for assigning custodianship of data assets. In this concept, a custodian is the entity responsible for managing access, protection, retention, and compliance for a given resource, while custodianwhich specifies who should take on that responsibility in a given context.

The name blends custodian with which to indicate the moment of choice in custody assignments. It is not a formal standard but a label found in governance literature and vendor discussions dating from the early 2020s, used to discuss how custody responsibilities are allocated.

Mechanically, custodianwhich can be implemented as a policy engine, workflow, or decision-support tool. It analyzes metadata, data classifications, regulatory constraints, and stakeholder requirements to produce a custody assignment. Proposals may be logged for auditability and adjusted as conditions change.

Applications include enterprise data lakes, shared archives, cloud storage, and privacy-compliance programs where explicit custodianship is needed to enforce access controls and retention schedules.

Variants range from rule-based custodianwhich that follows fixed policies to AI-assisted versions that infer assignments from historical patterns. Each variant emphasizes transparency and traceability, given the potential for bias or misassignment in automated decision processes.

Critics note the lack of standard definitions and the risk that ambiguous authority can undermine governance. Proponents argue that, when well designed, custodianwhich improves attribution, accountability, and policy alignment.
