About Us

Welcome to the MaRDI Knowledge Graph Portal

Welcome to the MaRDI Knowledge Graph Portal — your gateway to open mathematical research data. Access our comprehensive MaRDI knowledge graph integrating data from sources like DLMF, CRAN, PolyDB, swMATH (partially), zbMATH (partially). Whether you are a researcher, a student, or simply someone passionate about mathematics, the MaRDI Portal is here to support your exploration, learning, and discovery with resources tailored to diverse needs and interests.

We embrace the open-source philosophy — our source code repositories and detailed technical documentation are freely accessible. Or, maybe you want to read about our personas - some fictional characters that embody the distinct goals, motivations, and challenges of our users. If you have further questions or recommendations, you can find ways to contact us here.
