Revised2

Revised2 is a formal revision of the Revised data interchange specification, designed to improve interoperability, safety, and scalability in document and data exchange workflows. It supersedes Revised1 and provides the basis for tooling and standards within the Revised family.

Development and history

Drafted by the Revised Working Group, development began in 2021 with input from industry, academia, and government bodies. The specification was published in 2023 after public drafts, interoperability tests, and a formal review process. It aims to balance expressiveness with implementation efficiency while clarifying semantics across platforms.

Technical overview

Key features include a clearly defined schema language, support for streaming and partial updates, and improved error reporting. The specification defines a compact binary encoding with an optional JSON representation, explicit version negotiation, and a backward-compatible data model that allows validators to operate without executing payloads. Revised2 also emphasizes modular extensions and a formal validation framework to improve reliability in diverse environments.

Impact and adoption

Adoption has grown in sectors such as finance, healthcare, and research data exchange. Several major libraries added Revised2 support, and migration tools exist to convert Revised1 documents. Some ecosystems report an initial learning curve and tooling gaps during the transition, though the standard is gaining traction in new projects that require stronger compatibility guarantees and clearer validation pathways.
