## SAREF extension for industry and manufacturing domain: Description back to ToC

SAREF4INMA focuses on extending SAREF for the industry and manufacturing domain to solve the lack of interoperability between various types of production equipment that produce items in a factory and, once outside the factory, between different organizations in the value chain to uniquely track back the produced items to the corresponding production equipment, batches, material and precise time in which they were manufactured. Figure 1 presents an overview of the classes and the properties included in the SAREF4INMA extension.
