ITDT: International Testbed for Dataspace Technology
Itsuki Matsunaga, Takashi Michikata, Noboru Koshizuka · 2023
Data utilization for efficiency and optimization is increasing in many fields, and it is expected to create new value by sharing data among multiple stakeholders. In addition to domain-specific data platforms, which are already prevalent in Europe and Japan, cross-domain data platforms are being developed to enable interoperable and sovereign data exchange across different domains. However, through an extensive survey, we found that as the requirements for data exchange vary with regulations and/or applications, data platform initiatives and the software tools they offer are scattered. Thus, we need an experimental environment where various data exchange platform technologies can be learned, developed, and tested in one place. The objective of this paper is to propose the establishment of the International Testbed for Dataspace Technology (ITDT), an academic and industrial testbed for data platform technology. The ITDT intends to provide an environment that facilitates the development and testing of interoperability, portability, and customizability for data platform technologies. We expect the ITDT to promote the advancement of data platforms, international collaboration, and the formation of a neutral technical community. This paper presents the requirements, architectural design, and future plans for the ITDT.
