The Dublin Core Metadata Initiative is an open forum engaged in the development of interoperable online metadata standards that support a broad range of purposes and business models. DCMI's activities include consensus-driven working groups, global conferences and workshops, standards liaison, and educational efforts to promote widespread acceptance of metadata standards and practices.

Development of Standards for Cataloguing and Indexing of Cinematographic Works.

Founded in Paris in 1938, FIAF is a collaborative association of the world's leading film archives whose purpose has always been to ensure the proper preservation and showing of motion pictures. Today, more than 120 archives in over 65 countries collect, restore, and exhibit films and cinema documentation spanning the entire history of film. The FIAF Cataloguing Rules (1991) are available online.

The IFLA Cataloging Section formed in 2002 a Working Group on FRBR, in order to provide a focal point within IFLA (International Federation of Library Associations and Institutions) for the ongoing support and development of the conceptual model, and to encourage the implementation of FRBR as a data model and a reference model for the bibliographic universe.

The CIDOC Conceptual Reference Model (CRM) provides definitions and a formal structure for describing the implicit and explicit concepts and relationships used in cultural heritage documentation. The CIDOC CRM is intended to promote a shared understanding of cultural heritage information by providing a common and extensible semantic framework that any cultural heritage information can be mapped to. It is intended to be a common language for domain experts and implementers to formulate requirements for information systems and to serve as a guide for good practice of conceptual modelling. In this way, it can provide the "semantic glue" needed to mediate between different sources of cultural heritage information, such as that published by museums, libraries and archives. The CIDOC CRM is the culmination of over 10 years work by the CIDOC Documentation Standards Working Group and CIDOC CRM SIG which are working groups of CIDOC. It is currently being elaborated by the International Standards Organisation as Draft International Standard ISO/DIS 21127 and the CIDOC CRM Special Interest Group to become an ISO standard.

The METS schema is a standard for encoding descriptive, administrative, and structural metadata regarding objects within a digital library, expressed using the XML schema language of the World Wide Web Consortium. The standard is maintained in the Network Development and MARC Standards Office of the Library of Congress, and is being developed as an initiative of the Digital Library Federation.

MPEG is a working group of ISO, the International Organisation for Standardisation. Its formal name is ISO/IEC JTC 1/SC 29/WG 11. The title is: Coding of moving pictures and audio. The are of work assigned to it is: Development of international standards for compression, decompression, processing, and coded representation of moving pictures, audio, and their combination, in order to satisfy a wide variety of applications. Established in 1988, the group has produced MPEG-1, the standard on which such products as Video CD and MP3 are based, MPEG-2, the standard on which such products as Digital Television set top boxes and DVD are based, MPEG-4, the standard for multimedia for the fixed and mobile web, MPEG-7, the standard for description and search of audio and visual content and MPEG-21, the Multimedia Framework.

The Open Archives Initiative develops and promotes interoperability standards that aim to facilitate the efficient dissemination of content. The Open Archives Initiative has its roots in an effort to enhance access to e-print archives as a means of increasing the availability of scholarly communication. The fundamental technological framework and standards that are developing to support this work are, however, independent of the both the type of content offered and the economic mechanisms surrounding that content, and promise to have much broader relevance in opening up access to a range of digital materials. The Open Archives Initiative Protocol for Metadata Harvesting (OAI-PMH) defines a mechanism for harvesting XML-formatted metadata from repositories.
