Developing specifications for applications to publish, discover, update and access context information for smart cities and other areas.

From the digitizing of industrial processes to creating smart services for citizens, it is essential to accurately record data together with its context information, the so-called metadata, and to transfer these without misinterpretation to other systems. Single-purpose solutions (such as measuring temperature at a weather station) work well within a known/preset context, but transfer of the data to another system (e.g. personal travel planner) or another country (e.g. from UK to France) requires pre-agreed standards. A century of international collaborations has achieved thousands of such agreements, but technologies such as Big Data, semantic web, Linked Data, autonomous decision making and eGovernment are enormously forcing the pace.

Our ISG on cross-cutting Context Information Management (ISG CIM) is developing Group Specifications (GSs) for applications to publish, discover, update and access context information, initially for a broad range of smart city applications and later for other areas.

In 2017 work progressed in five areas. These include the collection and analysis of use cases, the identification of a general architecture and an analysis of the huge range of existing guidelines, standards and context information formats. An initial definition of a flexible information model was agreed, which is compatible with linked data, the Internet of Things (IoT) and relational databases. A preliminary version of an Application Programming Interface (API) to enable almost real-time access to information coming from many different sources (in addition to the IoT) was nearing completion.

ISG CIM has already benefited from advice of experts in ETSI SmartM2M, oneM2M, W3C Web-of-Things and (during an open workshop and via contributions from members) from a number of relevant H2020 projects. The next steps involve collaboration with other SDOs and experts to facilitate the best possible interworking between existing widely used systems, as well as to take account of provenance, security and privacy issues. As a matter of policy, introductory and intermediate material is regularly made publicly available at our open area (https://docbox.etsi.org/ISG/CIM/Open).
