This deliverable (entitled “Data Marketplace: Design and Open Specification”) describes the initial design and specifications of the PolicyCLOUD Data Marketplace. The Data Marketplace will be a unified web- based platform consisting of two (2) core services, its front-end and back-end, offering its users various ready-to-use solutions. More specifically, it will provide to the wider research and innovation community various assets (i.e. objects/solutions) in different domains.
As a Marketplace, the current design provides information on how several users (and contributors) can interact with the Marketplace in order to ingest and retrieve the respective assets, through potential user journeys that are analyzed. Moreover, the deliverable introduces the different types of offered assets, since the Data Marketplace will go beyond policies and tools and will store and offer additional elements, including rich descriptions of the offered assets, algorithms, validation datasets, and in general different outcomes of the project.
To support the aforementioned functionalities, the PolicyCLOUD Data Marketplace specifications exemplify the respective layers of the Marketplace, the functionalities supported by each layer, the interaction points with different stakeholders as well as the technical details that will drive the implementation of the Marketplace. Finally, it reviews the current state of the art in order to identify the baseline technologies and approaches for the realization of the implemented Marketplace.
