Towards Semantic Representation of Dataspace Technology Platform Architecture

Abstract

This paper explores the architectural princi ples and semantic aspects of building data space platforms with a focus on the MobiSpaces project centered on mobility and personal data protection. The paper describes the main technological components of the IDS RAM reference architecture, including data connectors, authentication, and certification services. Solutions for implementing an access security model, such as annotation of personally identifiable information and attribute-based access control (ABAC), are presented. Special attention is paid to state-of-the-art authentication techniques, including passwordless authentic cation using the FIDO2 standard and the use of electronic identity documents (eIDs), which contribute to achieving a high degree of trust and interoperability within data spaces. A key contribution of the research is the use of semantic technologies (in particular, the SCn/SCg OSTIS language) to describe architecture and access control, which increases the flexibility and context awareness of systems when exchanging data. The combined application of FIDO2 and ABAC is seen as a promising direction in the development of scalable and secure digital ecosystems.
