SODIC is a research group at TU Chemnitz focused on advancing open and semantic data infrastructures.
We explore how structured, interoperable and spatially linked data can foster innovation, transparency, and collaboration across public administration, science, and civil society.
In a world increasingly driven by data, the accessibility, semantics, and interoperability of Open Data are more important than ever.
SODIC stands at the intersection of technology, governance, and transparency – pushing for intelligent Open Data infrastructures that empower society, science, and administration.
