Fostering transparency, interoperability, and innovation in the Open Data ecosystem
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.
An interactive map-based tool linking Open Data portals to administrative boundaries across Europe. Introduced at ICEGOV 2025, SODREPO brings spatial context and metadata richness to the Open Data infrastructure landscape. Current demonstration is here: SODREPO
SODINA is a lightweight introspection layer for SPARQL endpoints, designed to support semantic data exploration by dynamically exposing available classes, properties, datatypes, and value samples. Inspired by GraphQL’s `__schema` functionality, SODINA lowers the entry barrier for users unfamiliar with the internal vocabulary of RDF-based Open Data portals.
This Node.js-based research tool analyzes the metadata quality of German municipal Open Data portals. Specifically, it evaluates the **regional assignability** of datasets depending on whether standardized metadata models like **DCAT-AP** and **GeoDCAT-AP** are used (typically via CKAN), best practice as a SPARQL endpoint, or non-standard formats (e.g. ArcGIS JSON).
