How to improve semantic interoperability? a concrete use case based on EUMED metering profile in the context of energy data space projects

In the context of information exchange between energy domains and across different sectors (such as Energy, Manufacturing, and Mobility) semantic interoperability between systems becomes an essential requirement. This paper addresses semantic interoperability lessons learned based on a concrete use case: Access to Metering and Customer Data. It leverages some results from Horizon Europe Energy Data Space projects, specifically OMEGA-X, EDDIE, Enershare, DataCellar and Int:Net.
