ETSI Releases Specification to Benefit Smart Cities

The European Telecommunications Standards Institute (ETSI) Industry Specification Group (ISG) for cross-cutting context information management (CIM) released its first specification, GS CIM 004. This specification defines a simple way to send or request data and its context such as the meaning, related information, source or licensing of that data.

Smart cities will be the first to benefit from this specification. Group Specification CIM 004 defines a standard application programming interface (API) for CIM enabling close to real-time access to information coming from many different sources. ETSI Group Specification CIM 004 addresses the strong synergies between seven spheres of information interacting in a smart city including internet of things (IoT), mobile application inputs, artificial intelligence or machine analysis, and others.

"Knowing the source, meaning and reliability of data is absolutely critical in making decisions, especially where legal liability exists,” said Dr. Lindsay Frost, chairman of ETSI ISG CIM, who acknowledged the fundamental work done to improve interoperability within many EC research and innovation programs. “After many discussions with various stakeholders, we confirmed that sharing data can benefit all parties as long as people — and software systems — know they are talking about the same things. The new ETSI ISG CIM specification allows systems to reference open definitions instead of assuming ‘in house’ definitions.”

There are thousands of ways to exchange data between software platforms, each with special benefits and usage. The new ETSI specification does not try to replace them, but offers a ‘lingua franca,” allowing the platforms to cooperate. Simplicity, reliability and ease of implementation have been the focus of the group to help lower barriers to deployment.

"Cities are looking for a minimum of interoperability focused on the two main layers of a smart city information system architecture: the lower one, between sensors and data storage, and the upper one to manage this data and make it useful for citizens,” said Christophe Colinet, vice-chair of ETSI ISG CIM and smart city projects leader in Bordeaux, France. “As we recently experienced in Bordeaux, oneM2M, ETSI partnership project, already provides a standards-based glue between sensors and the data storage system. I’m convinced the new ETSI ISG CIM specification, which addresses the upper level, will close the loop and enable the open and sustainable smart city information system architecture users are looking for.”
