Within the work performed as part of Task T1.1 in NanoSolveIT , an interoperability layer was implemented between the nanosafety knowledge base research at Maastricht University, represented by this work, and the BioXM knowledge management environment (BioXM-KME) , also called, the NanoCommons knowledge base . In order to achieve interoperability, SPARQL queries were written and tested for each API endpoint used by BioXM-KME and proper mappings between the query variables and the API fields were established. The interoperability layer utilized 11 SPARQL queries to expose the NanoLinks-KG data through BioXM API. BioXM-KME uses a comprehensive semantic model that is built upon existing ontologies:
