Setting the standard for open collaboration.
OASIS Open is where individuals, organizations, and governments come together to solve some of the world’s biggest technical challenges through the development of open code and open standards.
Our work
Projects & Committees

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.
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 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.
Unstructured Information Management Architecture (UIMA) v1.0
Defines platform-independent data representations and interfaces for software components or services called analytics, which analyze unstructured information and assign semantics to regions of that unstructured information.
The work of OASIS is supported by organizations from around the world. Members include:
