OASIS Standards & Releases
Chances are you’ve been touched by at least one of our standards over the last 24 hours. Our members produce work that defines how the internet exchanges information.
OData Version 4.01
OData enables the creation and consumption of REST-based data services which allow resources, identified using Uniform Resource Locators (URLs) and defined in a data model, to be published and edited by Web clients using simple HTTP messages. OData helps create a more open, programmable Web, and simplifies the querying and sharing of data across applications for re-use in the enterprise, cloud, and mobile devices.
Universal Business Language Version 2.2
Defining a generic XML interchange format for business documents that can be restricted or extended to meet the requirements of particular industries.
OData JSON Format v4.01
OData enables the creation and consumption of REST-based data services which allow resources, identified using Uniform Resource Locators (URLs) and defined in a data model, to be published and edited by Web clients using simple HTTP messages. This document extends the core specification by defining representations for OData requests and responses using a JSON format.
The work of OASIS is supported by organizations from around the world. Members include:
