This article is based upon the open plenary talk given at the NISO Plus Conference on February 14, 2023. David Weinberger, an American author, technologist, and speaker, explores the effect of the Internet and AI on metadata. He discusses how traditional metadata has had to anticipate the uses to which it will be put, who will use it, how users will navigate it, how it will be encoded, and how much metadata is enough. He asserts that the Internet has changed that because it encourages the adoption of the strategy of unanticipation.
