Metadata describe information products. In technical communication, metadata frequently includes validity, target groups, variants or content types. They can originate from various machine and/or manual sources and are managed and evaluated in various information systems (editorial systems, PIM systems, content delivery systems, etc.).
Meta metadata describe metadata, they make a statement, for example, about the origin of metadata or about their reliability.
An example: Metadata can be generated with AI methods. Given information products are analyzed automatically and the presumed metadata is derived from a number of different parameters. Reliability, i.e., the probability that the metadata has been correctly assigned, is one such meta-metadata and is important for the further use of the generated metadata.
Meta-metadata also includes statements about the actors involved in the creation of metadata (persons, organizations, SW systems), which may play a role in the use of the metadata.
