title: A METS BASED INFORMATION PACKAGE FOR LONG  TERM ACCESSIBILITY OF WEB ARCHIVES
creators: Markus Enders
abstract: 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.
