Oxford Common File Layout (OCFL)

This Oxford Common File Layout (OCFL) specification describes an application-independent approach to the storage of digital information in a structured, transparent, and predictable manner. It is designed to promote long-term object management best practices within digital repositories.

Specifically, the benefits of the OCFL include:

  • Completeness, so that a repository can be rebuilt from the files it stores
  • Parsability, both by humans and machines, to ensure content can be understood in the absence of original software
  • Robustness against errors, corruption, and migration between storage technologies
  • Versioning, so repositories can make changes to objects allowing their history to persist
  • Storage diversity, to ensure content can be stored on diverse storage infrastructures including conventional filesystems and cloud object stores
