Identity metadata is information that describes and provides context about other data entities (or identities - which can be human, machine, AI, or just an individual data node). Often referred to as “data about data”. An easy example here would be online streaming services, using metadata to manage its vast library of movies, tv-series and music. Descriptive metadata such as titles, genres, cast, release dates, together with technical metadata such as file formats, resolution etc, and usage metadata like ratings and personal preferences are all used together to enhance search, give personalized content recommendations, and provide detailed information to users.
