Invitation to comment on OData Vocabularies v4.0

Public review ends July 24th

OASIS and the OASIS Open Data Protocol (OData) TC [1] are pleased to announce that OData Vocabularies Version 4.0 is now available for public review and comment. This 30-day review is the second public review for this specification.

The Open Data Protocol (OData) enables the creation of REST-based data services, which allow resources, identified using Uniform Resource Locators (URLs) and defined in an Entity Data Model (EDM), to be published and edited by Web clients using simple HTTP messages.

OData Vocabularies v4.0 describes a set of OData vocabularies maintained by the OASIS OData Technical Committee. These vocabulary components are continuously evolved.

The documents and related files are available here:
