Object Management Group Issues Request for Proposal for DDS Consolidated JSON Syntax (DDS-JSON) Specification
Extends reach of Data-Distribution Service as core IIoT connectivity framework standard

Needham, MA – April 17, 2018 – The Object Management Group® (OMG®), an international, open membership, not-for-profit technology standards consortium, issued a Request for Proposal (RFP) for DDS™ Consolidated JSON Syntax (DDS-JSON). Letters of Intent to submit are due by September 7, 2018, and submissions are due by November 12, 2018.

Because the OMG Data-Distribution Service™ specification is deployed in a large number of complex mission-critical systems, such as industrial control systems including transportation, medical devices, smart grids, healthcare, smart cities and aerospace, it requires the integration of different connectivity frameworks. Key to DDS is the specification of gateways that bridge disparate communication protocols. The goal of the OMG DDS-JSON (JavaScript Object Notation) RFP is to draft a specification using the lightweight, text-based, platform-independent JSON data interchange format to represent DDS-related resources such as DDS Quality of Service (QoS), DDS Data Types, and DDS Entities (DomainParticipants, Topics, Publishers, Subscriber, DataWriters and DataReaders).

RFP author Fernando Garcia-Aranda, senior software engineer at Real-Time Innovations, an OMG Gold sponsor and BOD member, said: “DDS has been identified as one of the core connectivity framework standards of the Industrial Internet of Things (IIoT) by the Industrial Internet Consortium®. We believe this RFP will help extend the development of solutions for those interoperability scenarios that are crucial to the IIoT. The RFP aims to achieve a specification that employs a reusable syntax that can be leveraged to draft new specifications enriching the DDS ecosystem—especially in those defining new standard connectivity gateways.”

“JSON has become an increasingly popular lightweight syntax used to represent structured data and is often used in RESTful environments. This will enable system engineers and manages to apply DDS across a wider range of Internet of Things consistent with the goals of the OMG Model Driven Architecture®, which enables the definition of a single solution to be implemented over multiple technologies,” said OMG Vice President and Technical Director Larry L. Johnson.
