From the TC 372 Workshop Compendium

Metadata about audiovisual media comes in many shapes. Depending on the usage context, it can focus on the physical or digital artefact, the public release, the artistic creation, the commercial product, the historical evidence, or whatever.

So far, only few efforts have been untertaken to integrate at least some of these contexts within a metadata specification.

Specs-film-archives.png

Few guidelines and specification address the work of film archives directly.

The FIAF rules were published in 1991. Encoding of elements follows ISBD, which is mainly a presentation syntax. A major revision based on the recently published RDA is in progress.

MAVIS is the only major database application specifically designed for firm archives. It uses a detailed data model centered around two main entities: the content of a film and its carrier. The manufacturers of MAVIS went out of business in 2007.

Most other cataloguing applications for film archives are client-specific configurarions of database or document management systems.

Tv-archives.png

Most committee standards from the television sector have a strong focus on the digital production and distribution chain. Most TV broadcasters use these standards selectively, e.g. when supported by digital video production equipment and systems.

In-house metadata specifications are common and some of them are highly complex data models.

Media-distributors.png

ISAN is a numbering scheme for audiovisual media products similar to the ISBN for books. Members of the ISAN committee have contributed to the CEN standardisation process.

TV Anytime was an industry initiative that has produced a number of. MPEG-7 compatible metadata definitions for use with consumer devices such as digital video recorders.

ONIX is a series of metadata standards for the publishing industry and the book trade.

Numerous specifications exist for expressing rights and restrictions as metadata, usually for embedding in digital media objects.

Core-standards.png

Dublin Core is an ubiqitous standard applied to all kinds of digital resources. Using it for cinematographic works is problematic, however, since e.g. the notion of creator does not match well with the notions of cast and credits.

PBCore is a simple schema used for metadata exchange among public broadcasters in the U.S.

EBUCore is a minimalist counterpart to P/Meta, recently introduced by the European Broadcastung Union.

The FIAT/IFTA data element list is a members-only document.

EN 15744 can also be regarded as a core or minimalist standard.

Library-standards.png

Library standards are widely used in film archives, predominantly for non-film items and for film copies available for viewing.

Library standards are known for good interoperability among compliant implementations and for poor interoperability with most other metadata standards.

RDA offers a choice of encodings in addition to MARC.

For a discussion of RDA interoperability issues, see [1]

Archive-standards.png

These standards define elements and terminology for describing the contents of archives from the fonds level down to the item level.

EAC defines an XML-based encoding for such descriptions.

Museum-metadata.png

CCO grew out of a set of rules for describing images of museum objects and includes rules for objects as well as for collections of these. VRA Core is an encoding scheme for descriptions based on CCO, centered around three major entities: collection, object, and image.

CDWA is a comprehensive model and rule set for many kinds of objects relevant to the cultural heritage community. It has many definitions in common with CCO.

LIDO is an XML-based encoding of a subset of CDWA. Version 1.0 has been released in November, 2010.
