Object Management Group Board of Directors Adopts DDS-XRCE Specification
Zero-cost, high level data-sharing specification for constrained environments

Needham, MA — July 13, 2018 — The board of directors of the Object Management Group® (OMG®), an international, open membership, not-for-profit technology standards consortium, adopted the DDS-XRCE specification at its members meeting from June 18-22 in Boston, Massachusetts. The goal of DDS-XRCE (Data-Distribution Service for eXtremely Resource Constrained Environment™) is to deliver the benefits of the Data-Distribution Service™ (DDS™) databus to resource-constrained devices.

DDS™ is a family of standards from OMG that provides connectivity, interoperability and portability for industrial internet, cyber-physical, and mission-critical applications.

“The new DDS-XRCE specification extends the security, scalability, performance and quality of service benefits of the DDS databus to resource-constrained devices,” said Dr. Gerardo Pardo Castellote, OMG Board of Directors Member and CTO at RTI, one of three submitters for this specification. “This includes limited CPU and memory devices (e.g. micro controllers with less than 64 KB of memory), devices using very low-bandwidth communications (e.g. LoWPANs, IEEE 802.15.4 and ZigBee), and battery-powered devices that need to undergo deep-sleep cycles. The DDS-XRCE specification will enable new applications in smart city, agriculture and transportation systems to leverage the DDS databus. It will allow them to use the same DDS connectivity technology recommended by the Industrial Internet Consortium® in the Industrial Internet Connectivity and Security Framework architectures.”

“At eProsima, we are already testing this new specification in real scenarios, extending the use of DDS in the Robot Operating System (ROS) to tiny micro controller-based sensors and actuators,” said Jaime Martin Losa, eProsima CEO, OMG member and DDS-XRCE submitter.

"DDS-XRCE brings the power and flexibility of DDS technology to highly-constrained edge devices. The ability to integrate into existing DDS architectures, coupled with multi-vendor interoperability and support, makes this new protocol an exciting choice for Industrial Internet applications,” said Clark Tucker, CEO of Twin Oaks Computing, OMG member and DDS-XRCE submitter.

All existing OMG specifications are available for free download.
