The MARKET4.0 project coordinated by INTRA aims at implementing an e-marketplace for industrial equipment trading based on a peer-to-peer Industrial Data Space (IDS)-based infrastructure, providing key enabling technologies in terms of communication and collaboration in advanced multisided platforms. MARKET4.0 provides an open and secured API for data & services sharing, so that app developers can extend the functionality of the marketplace, e.g. by introducing new apps for additional production equipment domains. Additionally, MARKET4.0 integrates a number of “plug & produce” enabling services (publication of product catalogues, matching of requested products/demands and available products/supply, management of virtual networks of production equipment suppliers, feedback provision to the use of production equipment from the customer to the supplier, a web-portal that provides advanced user experience through simulation capabilities) that are needed for the functioning of the marketplace.
