Ensuring metadata quality of e-legal deposit in an ever-changing environment

The new Swedish Law on legal deposit of electronic documents, fully effective from January 1 this year, poses an exceptional challenge for the National Library of Sweden (NLS) by the sheer volume of documents of a wide variety of media types expected to be delivered by thousands of publishers (suppliers), such as government agencies, online news media, publishing houses etc. This naturally requires a high level of automation in the data processing, from ingest to validation, transformation, enrichment and storage, while at the same time attaining best possible metadata quality. To meet the challenges thus encountered the NLS has developed new electronic systems and workflows which will be roughly explained in this paper. We also try to touch on some of the issues that appear on the road regarding metadata quality, library catalogs and the ever-changing environment.
