  19. Metadata

  20. What is Metadata? • Different meanings in different communities • Information about information • Can describe information at any level • Collection • Item • Item within item • Can be embedded within an object or separate from it

  21. Types of Metadata • Descriptive • Descriptive metadata helps users find and obtain objects, distinguish one object or group of objects from one another, and discover the subject or contents. • Administrative • Helps collection managers keep track of objects for such purposes as file management, rights management, and preservation. • Structural metadata • Documents relationships within and among objects and enables users to navigate complex objects, such as the pages and chapters of a book. • Linking or relationship data

  22. Principles of Metadata • Have a community standard • Conforms to the needs of current and potential users • Supports interoperability • Distributed networked environment • Find resources that are distributed across the world’s libraries, archives, museums. • Includes a clear statement of the conditions and terms of use for the digital object.

  23. Principles of Metadata …contd. • Supports the long-term management and preservation of objects in collections.

  24. Metadata and Cataloguing • Perception that cataloguing is old and metadata is new • Traditional cataloguing focuses on descriptions of print materials • Metadata focuses on management of networked resources • For locally created or managed networked resources (such as repositories), cataloguing is insufficient

  25. Metadata Schemes • Defines a collection of elements for supporting a specific function • Defines structures for element values • Defines formal aspects of the element set, such as name, definition, data type, etc. • Some schemes are expressed as XML schemas

  26. Some Common Standards • Dublin Core • MARC 21 • Metadata Encoding and Transmission Standard (METS)
