datatag

Datatag is a term used to describe a label or marker that carries data associated with an object, record, or dataset. In a broad sense, datatags are used to identify, classify, track, or protect items by attaching metadata or coded identifiers. The term can refer to generic data tagging in software, as well as to specific brand offerings that market data-verification technologies.

In information technology, datatags appear as metadata fields, tags, or labels attached to records in databases, data lakes, and content management systems. They support search, filtering, governance, and access control by encoding attributes such as owner, sensitivity, lifecycle stage, or provenance.

A notable use of the name Datatag is Datatag ID Ltd., a British company that provides vehicle identification and anti-theft marking technology. Its systems combine microdots, RFID chips, and unique marking schemes with a registration database to verify ownership and aid recovery of stolen vehicles.

Beyond automotive applications, datatags are used in asset tracking, supply chains, and security labeling, often integrating with barcodes, QR codes, or RFID. They can enhance inventory control and provenance tracking but also raise privacy considerations and require careful planning to ensure interoperability and data protection across devices and platforms.
