Public review ends September 27th

OASIS and the OASIS Open Data Protocol (OData) TC are pleased to announce that four OData Version 4.02 work products are now available for public review and comment. 

The OData TC defines an open data protocol for sharing data and exposing data models interoperably on the Web, enabling the creation of REST-based HTTP data services that allow Web clients to publish and edit resources using simple HTTP messages. Version 4.02 revises the OASIS Standard OData Version 4.01. This is a second public review of these work products; each was approved as Committee Specification Draft 02 by a Full Majority Vote of the TC on 19 August 2026.

The documents and all related files are available here:
