Data marketplaces and data spaces have become a new trend aiming to provide platforms so that companies and researchers can exchange datasets in a secure way. Data has become a new currency and its crucial to be able to get access to high quality datasets to quickly and easily gain some knowledge towards meeting your objectives. However, most such existing platforms are centralised, gathering all the datasets in the cloud or some central servers, without providing high privacy or not giving providers or consumers the necessary supplies to assess or improve the quality of the datasets they exchange.
SEDIMARK aims to change the domain of data marketplaces contributing to the decentralisation of data exchange platforms, providing their users with the needed tools for improving data quality and building knowledge upon the data.
This document presents the final complete version of the SEDIMARK functional and system architecture, aiming to provide details on what functionalities the SEDIMARK platform will provide and how these will interact to meet the main objectives of the project. SEDIMARK builds upon the concepts of trust, decentralisation, interoperability, data quality and intelligence to provide a fully decentralised data and services marketplace, where providers and consumers will be able to share their data and build knowledge upon them.
Before presenting in detail the system architecture, this document provides a complete list of the terms and concepts defined and used within the project so that the readers can understand how these terms are used within the context of SEDIMARK. The main actors are also defined, mainly split into (i) providers, who are providing data, ML models, or services and (ii) the consumers, who are consuming the assets that are provided.
This deliverable leverages the results of the SEDIMARK Deliverable D2.1 [1], in particular the work done in Task 2.1 (Use Cases definition) focusing on project use cases and T2.2 (Requirements Elicitation) focusing on system requirements. This deliverable also builds upon the SEDIMARK Deliverable D2.2 [2] which presented the initial version of the architecture. In this deliverable a refined list of requirements is also provided based on the feedback from the above tasks and deliverables, with several new requirements added in some categories.
This document also presents the final versions of internal and external interfaces of the SEDIMARK platform, providing a view on how the components will interact with each other and how the main services will be provided. For the latter, example data flows are also presented, showing the messages exchanged between key components, towards providing the service. A final system view of the architecture also shows how the platform can be instantiated in the real world.
This final version of the SEDIMARK architecture aims to provide an architecture for designing decentralised data spaces and marketplaces for researchers and engineers and also ideas and concepts to EU initiatives (i.e. the DSSC) so that common reference architectures can be built.
