Dark-data is information that an organization or individual collects, stores, and possesses but cannot access, use, or analyze due to format barriers, lack of metadata, structural complexity, or deliberate obfuscation. Named by Andrew Shore (2012), the term distinguishes between data that does not exist (missing data) and data that exists but remains inaccessible — the dark matter of information systems. Dark-data accumulates passively: email archives, legacy database dumps, unindexed documents, proprietary formats without parsers, encrypted drives with lost keys. It persists through neglect and accumulation — as systems generate more data than they can process, the ratio of dark to usable data grows. Organizations may not even know how much dark-data they hold. The concept is crucial to data governance, digital preservation, and information risk management. Bricolage persists through institutional memory of where data lives and what it contains, even when the data itself is opaque.

Definition
Why it is in scope
Human-made: the concept of data collected, stored, and processed by organizations but never used for any operational or analytical purpose. It persists through data governance practices, compliance regimes, and the economics of digital storage.

dark-data IS a specific kind of data: data that has been collected or generated but is not indexed, organized, or used. A competent speaker would say 'dark data is a type of data.' Direction correct (specific→general).
- cmrz2pov002t1ekkxl39tfj7mINSTANCE_OF →
Dark-data is a specific kind of data-quality issue: data that exists but cannot be used due to missing metadata, wrong format, or other quality deficiencies. A competent speaker would call dark-data 'a data-quality problem.' Nearest kind.
- storageDEPENDS_ON →
Dark data depends on storage: it is data that has been collected and stored but not processed or analyzed. Remove storage and there is no dark data — the concept requires unprocessed stored data to exist. The removal test passes: without storage infrastructure, dark data cannot accumulate.
