Evolução do modelo de informação da Biblioteca Nacional Digital

Esta comunicação apresenta os aspetos mais significativos da evolução recente da estrutura de dados da Biblioteca Nacional Digital (BND), que se consubstanciam na definição de um novo modelo de objeto digital alinhado com o modelo de referência OAIS (Open Archival Information System); na aplicação de novos esquemas de metadados internacionais como o PREMIS (Preservation Metadata Implementation Strategies) e o MIX (Metadata for Images in XML); na formalização de um perfil de metadados para a BND; no desenvolvimento de uma ferramenta criada para a implementação deste novo modelo de informação digital e das operações de ingestão, acesso e administração do arquivo e, bem assim, na integração desse software com outas aplicações e sistemas de produção e gestão dos objetos digitais que constituem a BND

A METS based information package for long term accessibility of web archives

The British Library’s web archive comprises several terabyte of harvested websites. Like other content streams this data should be ingested into the library’s central preservation repository. The repository requires a standardized Submission- and Archival Information Package. Harvested Websites are stored in Archival Information Packages (AIP). Each AIP is described by a METS file. Operational metadata for resource discovery as well as archival metadata are normalized and embedded in the METS descriptor using common metadata profiles such as PREMIS and MODS. The British Library’s METS profile for web archiving considers dissemination and preservation use cases ensuring the authenticity of data. The underlying complex content model disaggregates websites into web pages, associated objects and their actual digital manifestations. The additional abstract layer ensures accessibility over the long term and the ability to carry out preservation actions such as migrations. The library wide preservation policies and principles become applicable to web content as well
