This online meeting is jointly organised by the Cooperation and Support Actions EU-IoT and ;

The meeting theme concerns semantic interoperability and specifically, the role of ontologies in providing interoperability. Semantic interoperability is one of the key pillars of open and flexible IoT systems. Ontologies are a key component of semantic interoperability, as they provide the foundation and capability for machines to interpret, infer knowledge from different data sets. Ontologies are, however, often vendor or protocol-based, and therefore, building universal ontologies or addressing mechanisms that can support an adequate interconnection across different ontologies is time-consuming and error-prone.

To assist in overcoming the mentioned challenges, this online workshop shall be dedicated to the discussion on the current status of ontological interoperability, provided by different key stakeholders and also provide a panel discussion for recommendations that can facilitate a better deployment of ontological interoperability across different vertical domains.

The expected outcome of this meeting is:

• An overview of key priorities and challenges being addressed by different SDOs, , AIOTI, BDVA/DAIRO, IAOTA, NIST,
• Feedback on recommendations that should be addressed in
• Additional suggestions for the coordination of standardization
