The Smart Applications REFerence Ontology (SAREF) defines a modular set of versioned ontologies that enable semantic interoperability between different Internet of Things (IoT) vendor solutions across various IoT industries. The European Telecommunications Standards Institute Specialist Task Force (ETSI STF) 578 recently completed the “Specification of the SAREF Development Framework and Workflow and Development of the SAREF Community Portal for User Engagement”. This project specifies the development pipeline and workflow needed to accelerate the development of SAREF and its extensions along with the development of software that automates the generation of ontology portal content from SAREF sources on the public ETSI Forge. This paper describes the SAREF Pipeline that provides an efficient and robust support infrastructure for the Continuous Integration and Delivery of semantic ontology development.
