Kennzeichnung

Kennzeichnung is the act of marking, labeling, or designating an object, person, or concept to convey identity, category, or provenance. It covers marking physical items as well as data, ideas, or processes, and is used across industries and disciplines to communicate essential information or distinctions.

In commerce and consumer protection, Kennzeichnung refers to labeling goods with information such as origin, ingredients, usage instructions, storage conditions, and safety warnings. Many jurisdictions impose Kennzeichnungspflichten to ensure traceability, prevent misrepresentation, and support informed decisions by consumers.

In information management and data science, Kennzeichnung also denotes tagging or labeling data and content with metadata or category labels to organize, search, and apply access controls. Consistent Kennzeichnung enables interoperability, governance, and efficient data handling within software systems and organizations.

In science, logistics, and shipping, Kennzeichnung includes the labeling of samples, products, and shipments, often with barcodes or QR codes to ensure traceability and proper handling. For hazardous materials, Gefahrenkennzeichnung uses standardized symbols and text to communicate risks and required precautions.

Etymology and usage: derived from the verb kennzeichnen, meaning to mark or identify. Related terms include Kennzeichen, referring to a distinguishing feature or identifier. Across contexts, the concept emphasizes clarity, traceability, and accountability in both physical and digital environments.
