Version 1.1 of the Oxford Common File Layout (OCFL) Released

*7 October 2022*

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 <https://ocfl.io/1.1/spec/> 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
<https://ocfl.io/1.1/implementation-notes/> 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
<https://ocfl.io/1.1/spec/validation-codes.html> and additional fixture
objects <https://github.com/OCFL/fixtures> for testing OCFL implementations
against the specification.

There is an accompanying Change Log
<https://ocfl.io/1.1/spec/change-log.html> 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.
