EvoluĆ§Ć£o do modelo de informaĆ§Ć£o da Biblioteca Nacional Digital
Esta comunicaĆ§Ć£o apresenta os aspetos mais significativos da evoluĆ§Ć£o recente da estrutura de dados da Biblioteca Nacional Digital (BND), que se consubstanciam na definiĆ§Ć£o de um novo modelo de objeto digital alinhado com o modelo de referĆŖncia OAIS (Open Archival Information System); na aplicaĆ§Ć£o de novos esquemas de metadados internacionais como o PREMIS (Preservation Metadata Implementation Strategies) e o MIX (Metadata for Images in XML); na formalizaĆ§Ć£o de um perfil de metadados para a BND; no desenvolvimento de uma ferramenta criada para a implementaĆ§Ć£o deste novo modelo de informaĆ§Ć£o digital e das operaƧƵes de ingestĆ£o, acesso e administraĆ§Ć£o do arquivo e, bem assim, na integraĆ§Ć£o desse software com outas aplicaƧƵes e sistemas de produĆ§Ć£o e gestĆ£o dos objetos digitais que constituem a BND
A METS based information package for long term accessibility of web archives
The British Libraryās web archive comprises several terabyte of harvested websites. Like other content streams this data should be ingested into the libraryās 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 Libraryās 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

A METS BASED INFORMATION PACKAGE FOR LONG TERM ACCESSIBILITY OF WEB ARCHIVES: Paper - iPres 2010 - Vienna
The British Libraryās web archive comprises several
terabyte of harvested websites. Like other content streams
this data should be ingested into the libraryās 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 Libraryās 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
