Metadata Standards & Content

BDS offers the most comprehensive catalogue of metadata available on home entertainment releases. Using BDS metadata across your whole supply chain will save you money, gain sales, ensure customer satisfaction and keep buyers returning.

Standards Matter

The importance of accurate and consistent metadata is paramount. BDS has established editorial rules which allow our team to add records with consistency and confidence. From the film or product’s title through to our in-house synopsis, every field of information, of which there are over 150, has been designed to provide the broadest and most granular record possible.

The record is then put through a rigorous proofing process with each record given the same effort and focus.

All Industry Standards

Industry standards, such as EIDR, and ISRC, NACO and ISNI are included in BDS metadata. Since none of these are unique outside their remit, BDS uses its own identifier as the overriding, unique identifier. This guarantees smooth operation, lack of duplication and easy search and retrieval.

Metadata Standards

Data standards are key to presenting consistent information that allows you to manage the large volume of metadata in your catalogue. The use of standards also ensures that your metadata is consistent with other organisations, important in a world where resources are shared.

BDS metadata incorporates all current cataloguing and classification standards across books, film, music and games, including:

  • BIC and Thema (find out more about BDS and Thema)
  • ISBN, EAN-13 barcodes and EIDR
  • EDI numbers for theatrical film releases
  • BBFC certificates
  • ISRC
  • MARC21, UKMARC or UNIMARC exchange format
  • NACO authority control for contributors
  • UK Standard Library Categories (UKSLC)

Granularity and Accuracy

The BDS database is built around coded choices and relationships to avoid typing errors and cloning. People, genres, publishers, labels, formats, availabilities, roles etc. have all been given their own codes within their own environments.


When information comes to us, the BDS editorial team assimilate and manually add it using our internal codes and rules, thus maintaining consistency and allocating products to the correct people and works. Every element has its own code from artists to item availability. No matter how simple automatic metadata feeds seem, as they are coming from different sources in a variety of formats, BDS intervention is paramount to ensuring accuracy and consistency.
