The MaRDI Portal

Your Portal to Open Math Research Data

About Us

Welcome to the MaRDI Portal of the NFDI.

Here, you can query our mathematical research data knowledge graph. Please keep in mind that this page is still in an early stage of development. Currently, supported data sources: DLMF, CRAN, PolyDB, swMATH (partially), zbMATH (partially).

We are supporting the open-source idea - you can find our source code repositories here. The technical documentation can be found here. If you have further questions or recommendations, you can find ways to contact us here.
