A RDF Validation Tool Extended On Jena-ShEx

RDF is the core technology of the Semantic Web direction, and RDF is increasingly being used to represent and store information shared over the Web. When data consumers reuse RDF graphs created by others, it is necessary to understand the structure of the current data, and the current use of human-readable descriptions or ontologies to convey knowledge is often insufficient, so the correctness of the RDF becomes the key to the correct dissemination of knowledge in the knowledge graph. Based on Jena-ShEx, this paper optimizes the correctness test of RDF, draws on the idea of SHACL in the generation of validation report, and refines the test report of RDF, so that data consumers can quickly locate and modify data when conducting data verification. The improved tool passed all the test cases on the Shape Expression website and achieved good results.
