OCFL Version 1.1
The OCFL Editors are pleased to announce version 1.1 of the Oxford Common File Layout. The focus of this revision is correction and clarification based on implementation experience and community feedback. Version 1.1 is backwards compatible with version 1.0.
What new information is available?
The OCFL website at https://ocfl.io/, includes the most up to date version of the specification and the implementation notes as well as the latest editors draft.
The OCFL Specification v1.1 defines both OCFL Objects, a simple structure for content and a JSON document (inventory.json) which provides a straightforward but comprehensive register for the object and versions of its content, and an OCFL Storage Root, an arrangement for how OCFL Objects are laid out on physical storage. It also contains examples illustrating the use of the OCFL, and explanations that ground decisions in prior experience.
The companion OCFL Implementation Notes v1.1 contains advice for implementing the specification including recommendations for digital preservation, storage handling, client behaviors, and best practices for dealing with OCFL Objects in motion.
The OCFL Editors are also releasing updated validation rules and additional fixture objects for testing OCFL implementations against the specification.
There is an accompanying Change Log that details the changes from version 1.0 to version 1.1. It is designed to assist implementers with updates to their implementations. We welcome your feedback, questions, use cases, and especially details of any implementations or experimentation with OCFL.

1.0 - Recommendation
The OCFL Editors are pleased to announce version 1.0 of the Oxford Common File Layout, reflecting over 24 months of work by the OCFL Editors and the digital preservation and technology communities.
The initiative originated in September 2017 from informal discussions at a Fedora/Samvera camp in Oxford, UK. These discussions identified the need for a simple, non-proprietary, specified, open-standards approach to the layout of files for the purpose of preservation persistence. Subsequently, a kickoff community meeting attracted 47 attendees from 32 institutions, confirming the need and resulting in the establishment of the OCFL Editors team.
The OCFL website at https://ocfl.io, includes the most up to date version of the specification and implementation notes as well as the latest draft. The press release detailing the release of the OCFL version 1.0 can be found on the news section of the OCFL website.
