Component IRIs link into the material graphs from both source datasets. All three graphs are loaded into this dataset's [Fuseki triplestore](https://dataportal.material-digital.de/dataset/203bde74-4e5f-4a74-a1d8-261e0f8ca84a/fuseki/$/sparql), enabling joint SPARQL queries that traverse from the physical object through its parts into material properties originating from two separate dataspaces. An [example SPARQL query](https://dataportal.material-digital.de/dataset/203bde74-4e5f-4a74-a1d8-261e0f8ca84a/resource/6f9909fd-10a5-47b0-9098-097a756b8b11/download/cross_dataspace_query.sparql) demonstrates this joint querying capability.
