Questions tagged [metadata]

Meta-data provides information about one or more aspects of the data. Meta-data may refer to either structural metadata (data about the containers of data) or descriptive metadata (data about data content).

Metadata may refer to either descriptive, structural or administrative metadata, which is data about data content.

Descriptive metadata describes elements such as title, abstract, author, and keywords to be associated with a document.

Structural metadata describes the types, versions, relationships and other characteristics of documents.

Administrative metadata provides information such as when and how a document was created, file type and other technical information, and who can access it.
