This document provides an introduction to the ETSI Industry Specification Group on Context Information Management (ISG CIM). It discusses the goals of ISG CIM, which are to develop technical specifications for exchanging contextual information across different domains. It outlines the scope and status of ongoing work items, including use cases, architecture and gap analysis, an API specification, information models, and security considerations. Examples of contextual information exchange across different smart city domains are also discussed.
