# The MatWerk Knowledge Graph and the two addresses it can be queried at. The endpoint is a separate individual reached
# from the dataset by obo:IAO_0000235 (denoted by), which is how the MatWerk sheet records it; each endpoint states its URL
# with nfdi:NFDI_0001008 (has url). Both addresses answered on 2026-10-22: the first returns SPARQL results, the second is the web interface.
