Integrating IoT Solutions by Common Vocabularies with Semantic Technologies

The present disclosure relates to computer-implemented methods, software, and systems for allowing Internet of Things (IoT) solutions to be integrated using common underlying vocabularies and lightweight reasoning to connect applications and validate IoT device data. In one example method, application-specific vocabularies for each of a plurality of applications are identified at design time, wherein each of the applications is associated with a corresponding vocabulary. At design time and for each application, an explicit mapping of the application-specific vocabulary of a particular application to a corresponding common vocabulary is identified. At runtime, implicit mappings between a first application and a second application to be integrated are computed based on the explicit mapping of the application-specific vocabulary of the first application to the common vocabulary and the explicit mapping of the application-specific vocabulary of the second application to the common vocabulary.
