Data Distribution Service for Real-Time systems V1.2 is a standard finalized in 2007 by the Object Management Group (OMG). Its goal is to provide a standardized infrastructure for building mission or business critical systems. For that purpose, it defines a strong-typed data-space that can be updated by Publishers and observed by Subscribers. Decoupling, automatic discovery and a rich set of Quality of Service settings are some of its important features.

Data Distribution Service (DDS) specification: https://www.omg.org/spec/DDS/
