Metadata standards
What are metadata standards?
Metadata standards are standardized schemas and serve to provide a structured, uniform description of resources. Standards result in a “common language” and support the understandability and interpretability of data as well as their interoperability.
A distinction can be made between different types of metadata standards. The standards therefore have different uses and serve different purposes. There are standards for the description of the data structure and semantics (formats), the content (rules), the values (norm data, controlled vocabularies) and for communication (interfaces, protocols).
