ETSI EN 303 760 provides guidance for developing IoT smart applications and products that are interoperable at the semantic level using the SAREF framework. It details how to apply SAREF, outlines a methodology to demonstrate compliance, and describes optional steps for contributing to a new SAREF extension.
ETSI EN 303 760: "SmartM2M; SAREF Guidelines for IoT Semantic Interoperability; Develop, apply and evolve Smart Applications ontologies".
The SAREF website has been fully redesigned with a modern look, improved ontology browsing, and site-wide term-based search to enhance navigation and usability.
