This deliverable (entitled “Data Marketplace: Software Prototype”) describes the final version of the PolicyCLOUD Data Marketplace demonstrator and is a follow up of the deliverable D7.5 - “Data Marketplace: Software Prototype” where the initial demonstrator of the Data Marketplace was described. In essence, the Data Marketplace is a unified web-based platform consisting of two (2) core services, the front-end and the back-end services, offering its users various ready-to-use solutions. More specifically, it provides to the wider research and innovation community various assets (i.e., objects/solutions) in different domains. Into this context, the current deliverable describes an overview of the Data Marketplace architecture, detailing the main features of its core components (also described in D7.4 - Data Marketplace: Design and Open Specification, delivered in August 2021, and its updated version D7.11, delivered in August 2022), whereas all the implemented interfaces are thoroughly described accompanied by indicative examples. On top of these, the baseline technologies that have been used for the realization of the Data Marketplace are analyzed, providing detailed information on how an external user can exploit and access the Data Marketplace.
