More about standards

European Article Number (EAN) Now renamed International Article Number

An EAN-13 barcode is a 13 digit (12 data and 1 check) barcoding standard which is defined by the standards organization GS1. The EAN barcode is the earliest most widely used physical product identifier that is found on consumer products globally. Unique EAN numbers are allocated to each separate retail product, not just by product brand but by variation of format e.g. DVD, Blu ray. Physical entertainment products that have the associated EAN make a commercial supply chain more effective by ensuring consumers receive the actual products they purchase as barcodes can provide an inexpensive and reliable method of tracking products.

Entertainment Identifier Registry (EIDR)

EIDR is a universal Digital Object Identifier (DOI) that uniquely identifies an audiovisual object. It is similar to an EAN code that is used to identify physical packaged goods. EIDR can be used for both physical and digital video objects that are part of the film and television supply chain. EIDR is an opaque ID with all information about the registered asset stored in a central registry.

British Board of Film Classification (BBFC)

The BBFC is a trusted guide to media content and is the UK’s regulator of film and video, providing age ratings to protect the public – especially children – from content which might raise harm risks and to empower the public – especially parents – to make informed viewing choices.

International Standard Recording Code (ISRC)

ISRC is an international standard code for uniquely identifying sound recordings and music video recordings. An ISRC identifies a particular recording, not the work (composition and lyrical content) itself. Therefore, different recordings, edits, and remixes of the same work should each have their own ISRC.

The International Standard Book Number (ISBN)

ISBN is a unique international identifier for monographic publications. Published as an international standard (ISO 2108) and in wide use since the 1970s it has been adopted in over 160 countries. Assigning an ISBN enables not only each publication to be uniquely identified but also rich product metadata to be associated with a particular publication record as well as the accumulation of sales data by specific title, edition and format.

MAchine-Readable Cataloguing (MARC)

MARC standards are a set of digital formats for the description of items catalogued by libraries, such as books. It was developed at the US Library of Congress to create records that can be used by computers, and to share those records among libraries. By 1973 MARC formats had become the standard for dissemination of bibliographic data around the world, the most predominant being MARC 21. BDSWest10 has created MARC records for Audio Visual products as well as books.

Name Authority Cooperative Program (NACO)

The underlying principle of the NACO Program is that participants agree to follow a common set of standards and guidelines when creating or changing authority records in order to maintain the integrity of a large shared authority file. BDSWest10 complies with these guidelines helping to build a consistent and predictable file that will reduce the efforts of the global library community and maximise its resources.

Games Rating Authority (GRA), BBFC (see above), European Leisure Software Publishers Association (ELSPA) Pan-European Game Information (PEGI)

GRA a trading name for the game rating activities of the Video Standards Council. Prior to 1994 there was no system available for use in rating video games, however games that contained extreme material, the equivalent of an 18 rating, were rated by the BBFC using film rating methodology. In 1994 the games industry introduced a rating system, known as the ELSPA System, which in turn was superseded by the PEGI system in 2003. The PEGI age rating system was established to help European parents make informed decisions on buying computer games and replaced a number of national age rating systems with a single system now used throughout most of Europe.
