Frequently Asked Questions


What is the OpenMAMA project?

OpenMAMA is an open source project hosted at the Linux Foundation. OpenMAMA provides a high performance Middleware Agnostic Messaging API that interfaces with a variety of message oriented middleware systems.

Why is it important?

What are examples of solutions or services that can be implemented with OpenMAMA?

Why is the project hosted at the Linux Foundation?

The Linux Foundation provides a neutral home for the industry and the open source community to collaborate on OpenMAMA.

What does the Linux Foundation hope to achieve with the OpenMAMA Project?

The project facilitates collaboration between various companies and open source developers to advance the implementation of an open source messaging platform. It is a one of a kind project, the first open standard and open source solution for the community.

How is OpenMAMA different from similar open source and commercial software?

Today there is no common open source API that connects multiple middleware transports to applications across multiple development platforms. OpenMAMA, unlike many other messaging APIs, focuses on the requirement for high throughput and low latency messaging. OpenMAMA is open source and vendor neutral. It is backed by a community of users and developers from numerous financial institutions, market data vendors, and technology firms.

Why do companies use OpenMAMA? What are the technical advantages of adopting it?

OpenMAMA offers an open standard that lowers cost and increases efficiency for all players. It prevents vendor lock-in and enables users to develop solutions without committing to a specific messaging platform. OpenMAMA is truly agnostic: you write your application once and it can be deployed on mulitiple messaging soulitons without any changes in the code or even recompiling. OpenMAMA is fast, scalable, supports multiple platforms and languages.

What are the economic benefits of OpenMAMA?

Adopting OpenMAMA:

Under which open source license is OpenMAMA made available?

OpenMAMA is licensed under the terms of the GNU Lesser General Public License version 2.1. You can view the full LGPLv2 license here:

What were the motivations for choosing that specific license?

LGPLv2 is an open source license that is more permissive than GPL. It provides more flexibility for both the users and developers of the code. It enables businesses to use the code for commercial applications and in return these commercial applications contribute back to the open source making the code richer in functionality and better in quality for all. The commercial portion of applications that use OpenMAMA remain proprietary under the LGPLv2 while changes to the OpenMAMA API are open source.

What is the governance model of the project?

The OpenMAMA project governance consists of a Steering Committee and a Technical Group.

The Steering Committee is responsible for:
Companies represented on the Steering Committee commit to:
The Technical Group is responsible for:

How to get involved?

The OpenMAMA project does not require a contributor agreement. The OpenMAMA project will neither require nor accept copyright assignments for code contributions to avoid extra bureaucracy or other obstacles discouraging contributions.


Who are the current participants in the project?

Please see the current members of the OpenMAMA Steering Committee, as well as other supporting organizations.

How does the roadmap get defined?

The OpenMAMA project accepts new requirements and new feature requests from its members and from the open source community through the mailing lists and bug tracking system. Roadmap items get defined and prioritized based on need, available resources and other factors and passed to the Steering Committee for approval. Once approved, the Technical Group starts working on the implementation of the defined roadmap items. For more information regarding this process, see the guide here.

Under which conditions can ISVs/OSVs use the OpenMAMA logo?

The OpenMAMA mark and logo may be used in accordance with the Linux Foundation Trademark Usage Guidelines in association with a product that has fulfilled all validation requirements of the OpenMAMA Compliance Program for that product and for the specific version and release of OpenMAMA that is indicated.

The objective of the OpenMAMA Compliance Program is to avoid confusion and to preserve the value of the OpenMAMA mark and to clearly and consistently communicate what is and what is not OpenMAMA in the marketplace. We believe that preservation of the mark is important for the benefit of the entire OpenMAMA community.

ISVs/OSVs will be allowed to use the OpenMAMA mark and/or logo if:

Are there any validation test suites available for OpenMAMA based stacks?

The OpenMAMA project will provide a suite of validation tests.

Is compliance mandatory?

The OpenMAMA Compliance Program is only mandatory for products that claim to use OpenMAMA. Since the OpenMAMA source code is open source, anyone can use it to build any kind of product, however should you claim or imply your product runs or is compatible with OpenMAMA you must meet certain compliance criteria. If a company wishes to use the OpenMAMA name or Logo with their product, they must first demonstrate that the product is in compliance and adhere to the compliance process.

What is the support plan for the OpenMAMA project?

Various commercial support plans will be offered for customers who need continuous availability and high degree of reliability. Developers might also require professional support for developing the codebase and adding functionality.

However, OpenMAMA is an open source project and can be downloaded and used as is without any support plan.
