“Athena” Research and Innovation Centre (ARC) participates in STELAR with its Information Management Systems Institute (IMSI). IMSI conducts R&I activities in the areas of data management and large-scale information systems, being one of the leading institutes in the EU in Big Data and Semantic Web technologies, i.e., the foundations of the Data Economy, with particular emphasis on geospatial and spatio-temporal data.

This is apparent in the quantity and quality of scientific publications in these fields, as well as from the success in obtaining competitive funding from EU and national programs, with more than 90% of IMSI budget coming from competitive funding. Moreover, IMSI has successfully led the design and implementation of several large-scale real-world information systems (e.g., hellenicdataservice.gr, geodata.gov.gr), daily offering their services to thousands of users.
