23、TSI ETSI GR CIM 002 V1.1.1 (2018-09)6 1 Scope The present document discusses the concepts which are foundational for Cross-Cutting Context Information Management (C3IM) and their application to a selection of Use Cases from the domains of Smart Cities, Smart Agrifood and Smart Industry. These areas
24、of application, together with the general area of Internet of Things (IoT) technology and services, are expected to especially benefit from usage of cross-cutting (cross domain) context information, and from a set of specifications for the APIs supporting C3IM. The present document covers the follow

An introduction to the notions of C3IM and the potential role of C3IM in enabling services in cross-cutting inter-domain areas, for example Smart Cities, Smart Agrifood, and Smart Industry. A motivation for t
26、his projects key goal, i.e. defining an API for C3IM. A reference diagram illustrating possible architectures and functional entities involved in facilitating C3IM. A set of high level Use Cases which can potentially be supported using a C3IM system. A subset of detailed Use Cases (scenarios) illust

45、, the present document concerns the application of cross-cutting contextual information management to a selection of Use Cases from the domains of Smart Cities, Smart Agrifood and Smart Industry. These applications are expected to especially benefit from cross-cutting context information and from a
46、set of specifications for the APIs supporting C3IM. ETSI ETSI GR CIM 002 V1.1.1 (2018-09)9 Cross-cutting Context Information Management (C3IM) is provided by a C3IM platform. A C3IM platform collects data from IoT devices, lower-level platforms managing such devices, crowdsourced devices, databases
47、and other sources, and provides as consolidated context information to applications via an API (defined in later documents as NGSI-LD). The C3IM platform enables use-cases which link together disparate but related information. It is thought that IoT services will be enriched when applications have a
48、ccess to a full set of context information, as defined in clause 3. A C3IM system potentially enriches services by bringing together information from a wider set of service-relevant sources than would otherwise be available to a traditional vertically integrated IoT application. This is illustrated
49、in figure 4.1-1. In the first figure, an IoT information source such as a sensor provides data to an application. As an example, an IoT-enabled fitness tracker device reports heart rate and step counts to a user via a cloud-based “runner fitness“ service. The user is simply able to access current values and past statistics for these measures. For best results and widest interoperability, the transfer of information from the sensor to the cloud application needs to be accompanied by the semantics and context of the information (i.e. the numbers sent are “hear
