Our work

Projects & Committees

Whether you want to start, lead, or contribute to a project, OASIS is the place to be. Here are some of our projects.

Open Mobility Foundation

Helping cities manage products that use the public right-of-way, including shared scooters, bikes, autonomous vehicles, and drones. OMF is an independent group hosted via OASIS Foundation-as-a-Service.

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.

WS-BusinessActivity v1.2

Provides the definition of two Business Activity coordination types: AtomicOutcome or MixedOutcome, that are to be used with the extensible coordination framework described in the WS-Coordination specification. This specification also defines two specific Business Activity agreement coordination protocols for the Business Activity coordination types: BusinessAgreementWithParticipantCompletion, and BusinessAgreementWithCoordinatorCompletion. Developers can use these protocols when building applications that require consistent agreement on the outcome of long-running distributed activities.

The work of OASIS is supported by organizations from around the world. Members include:
