Eraldatav

Eraldatav is a coined term in information science used to describe a property of data assets that permits persistent attribution and traceability across transformations and storage contexts. In practice, eraldatav refers to a design goal where data elements carry durable identifiers and provenance metadata that survive data processing, migration, and format changes, enabling reliable re-linking of records to their origins while supporting authorized auditing. The concept emphasizes both data lineage and the ability to re-associate transformed data with its source, within bounds set by privacy and access controls.

Origin and status: The term appears in a small number of speculative or fringe discussions and is not part of formal standards. There is no single accepted definition, and usage varies between communities. Some writers treat eraldatav as a broader umbrella for data provenance plus tamper-evident tagging, while others use it as a keyword for future interoperability work.

Characteristics: Durable identifiers embedded in data records; cryptographically protected provenance metadata; re-linkability across systems; configurable policy for who can view or modify provenance. Implementation often relies on data catalogs, immutable logs, and standardized metadata schemas.

Applications: Regulatory compliance, analytics auditing, healthcare, finance. Example: a patient record carried through data lake, ETL, and analytics deployment keeps a persistent identifier and chain-of-custody metadata that allows an authorized auditor to verify lineage without exposing sensitive content.

Challenges: Lack of standard definitions; measurement of durability; privacy concerns; performance impact; requires cross-organizational agreement on metadata models. Relationship to related concepts includes data provenance, data lineage, and defensible deletion.
