It allows one or more ontologies to be parsed and represented as Python classes, making it easier to navigate and explore their structure through features like autocompletion in interactive environments such as Jupyter notebooks. The framework preserves key semantic details such as domain and range information, which can then be used programmatically within Python workflows. A central goal of the tool is to make querying knowledge graphs with SPARQL more accessible to users without deep expertise in semantic web technologies. This is achieved through a programmatic interface that abstracts away much of the complexity involved in writing SPARQL queries. The overall workflow of the approach is illustrated in Figure 1, showing how tools4RDF parses ontologies, constructs a network representation, and generates SPARQL queries to retrieve data from knowledge graphs. This design lowers the barrier to entry for domain scientists and developers unfamiliar with RDF, while still exposing enough control for advanced use cases. Originally developed for ontology-driven data integration in materials science, tools4RDF is ontology-agnostic and can be used across a wide range of scientific domains. 001052752 536__ $$0G:(DE-HGF)POF4-5111$$a5111 - Domain-Specific Simulation & Data Life Cycle Labs (SDLs) and Research Groups (POF4-511)$$cPOF4-511$$fPOF IV$$x0 001052752 536__ $$0G:(GEPRIS)460247524$$aDFG project G:(GEPRIS)460247524 - NFDI-MatWerk - Nationale Forschungsdateninfrastruktur für Materialwissenschaft & Werkstofftechnik (460247524)$$c460247524$$x1 001052752 588__ $$aDataset connected to CrossRef, Journals: juser.fz-juelich.de 001052752 7001_ $$0P:(DE-Juel1)192552$$aAzocar Guzman, Abril$$b1$$eCorresponding author 001052752 7001_ $$00000-0002-1677-4057$$aWaseda, Osamu$$b2 001052752 7001_ $$0P:(DE-Juel1)186075$$aSandfeld, Stefan$$b3 001052752 7001_ $$00000-0003-0698-4891$$aHickel, Tilmann$$b4 001052752 773__ $$0PERI:(DE-600)2891760-1$$a10.21105/joss.09482$$gVol. 11, no. 117, p. 9482 -$$n117$$p9482 -$$tThe journal of open source software$$v11$$x2475-9066$$y2026 001052752 8564_ $$uhttps://juser.fz-juelich.de/record/1052752/files/10.21105.joss.09482.pdf$$yOpenAccess 001052752 909CO $$ooai:juser.fz-juelich.de:1052752$$pdnbdelivery$$pdriver$$pVDB$$popen_access$$popenaire 001052752 9101_ $$0I:(DE-588b)5008462-8$$6P:(DE-Juel1)192552$$aForschungszentrum Jülich$$b1$$kFZJ 001052752 9101_ $$0I:(DE-588b)5008462-8$$6P:(DE-Juel1)186075$$aForschungszentrum Jülich$$b3$$kFZJ 001052752 9131_ $$0G:(DE-HGF)POF4-511$$1G:(DE-HGF)POF4-510$$2G:(DE-HGF)POF4-500$$3G:(DE-HGF)POF4$$4G:(DE-HGF)POF$$9G:(DE-HGF)POF4-5111$$aDE-HGF$$bKey Technologies$$lEngineering Digital Futures – Supercomputing, Data Management and Information Security for Knowledge and Action$$vEnabling Computational- & Data-Intensive Science and Engineering$$x0 001052752 9141_ $$y2026 001052752 915__ $$0LIC:(DE-HGF)CCBY4$$2HGFVOC$$aCreative Commons Attribution CC BY 4.0 001052752 915__ $$0StatID:(DE-HGF)0501$$2StatID$$aDBCoverage$$bDOAJ Seal$$d2024-09-10T14:45:56Z 001052752 915__ $$0StatID:(DE-HGF)0500$$2StatID$$aDBCoverage$$bDOAJ$$d2024-09-10T14:45:56Z 001052752 915__ $$0StatID:(DE-HGF)0510$$2StatID$$aOpenAccess 001052752 915__ $$0StatID:(DE-HGF)0030$$2StatID$$aPeer Review$$bDOAJ : Open peer review$$d2024-09-10T14:45:56Z 001052752 915__ $$0StatID:(DE-HGF)0300$$2StatID$$aDBCoverage$$bMedline$$d2025-11-12 001052752 920__ $$lyes 001052752 9201_ $$0I:(DE-Juel1)IAS-9-20201008$$kIAS-9$$lMaterials Data Science and Informatics$$x0 001052752 980__ $$ajournal 001052752 980__ $$aVDB 001052752 980__ $$aUNRESTRICTED 001052752 980__ $$aI:(DE-Juel1)IAS-9-20201008 001052752 9801_ $$aFullTexts
