# Purpose Limitation **Domain:** Deep Time / Data Protection / Institutional Design **Doc Type:** Canonical Wiki Entry **Maturity:** Developed **Evidence / Concept Status:** Established data-protection principle ## Definition **Purpose Limitation** is the requirement that personal data be collected and processed for specified, explicit, and legitimate purposes and not casually repurposed incompatibly. ## Why It Matters for Deep Time Continuity It is the legal counterforce to function creep and therefore a critical deep-time safeguard. ## Existing Architecture / Evidence The UK ICO explicitly links purpose specification to avoiding function creep and preserving accountability and user understanding. ## Deep-Time Continuity Analysis A continuity system must specify whether data is for archive, training, reconstruction, authentication, memorialization, or active execution. ## Evidentiary Boundary Purpose limitation can constrain conversion but may itself need lawful amendment when the person expressly elects a new purpose. ## Related Ontology [[wiki/Function Creep|Function Creep]] · [[wiki/Continuity Election|Continuity Election]] · [[wiki/Human Digital Remains|Human Digital Remains]] · [[wiki/Deep-Time Institutional Conversion|Deep-Time Institutional Conversion]] ## Sources / Primary Anchors - https://ico.org.uk/for-organisations/uk-gdpr-guidance-and-resources/data-protection-principles/a-guide-to-the-data-protection-principles/purpose-limitation <!-- BEGIN DEEP TIME CONTINUITY ROUTING --> ## Canonical Branch [[wiki/Deep Time Continuity|Deep Time Continuity]] <!-- END DEEP TIME CONTINUITY ROUTING -->
