  • Licensed under the LGPL 2.1 license
  • Hosted at The Linux Foundation in a neutral environment that encourages collaboration
  • Follows open source development methods and processes
  • Includes open and accessible mailing lists, source code repository, and bug tracking systems
  • Participation is open to any developer, corporation or entity, provided that they abide by the terms of the project, and the LGPL 2.1

Why is OpenMAMA important?


  • Enables users to embrace new middleware technologies and applications as the market innovates
  • Independent from middleware technologies
  • Helps organizations speed up their time-to-market for event driven applications and improve their messaging middleware technology
  • High potential for market penetration outside of the financial sector, towards other sectors such as Telecommunication, High Performance Computing, Web Services and Logistics

Why is having a common messaging API important?

A common middleware agnostic messaging API provides several advantages:

  • It allows developers to bring applications to market more easily and rapidly, within any industry-standard middleware environment, irrespective of the network infrastructure.
  • It ensures high performance both in terms of throughput and message latency.
  • It provides commonality at API level but freedom to differentiate both at lower and higher stacks (ie. middleware technology and applications).

How OpenMAMA Works

OpenMama uses a common publish/subscribe idiom (pub/sub). In this messaging pattern the messages are not sent directly to the receivers, but published to a topic. Subscribers express interest in one or more topics, and receive only messages that interest them. This decoupling of publishers and subscribers allows for greater scalability.
