sheval: An RDF data shapes evaluation tool and test-suite for recursive shapes
Shqiponja Ahmetaj, Iovka Boneva, Jan Hidders +8
Two different languages have been developed to validate RDF data based on the concept of a shape: ShEx and SHACL. In each language it is possible to define a shape that refers to i…
Rewriting Ontology-Mediated Property Graph Queries into GQL
Bianca Löhnert, Nikolaus Augsten, Cem Okulmus +1
Ontology-based data access is intended for graph data, but practical support remains limited to SQL-like languages lacking the navigational and path-matching features fundamental t…
Shapes from Examples: Foundations of Shape Learning in Recursive SHACL
Bente Gortworst, Cem Okulmus, Magdalena Ortiz +1
SHACL shapes enable data graph validation, making automatic shape learning essential for knowledge graph applications. We investigate the well-known fitting approach to this task:…
Common Foundations for Recursive Shape Languages
Shqiponja Ahmetaj, Iovka Boneva, Jan Hidders +9
As schema languages for RDF data become more mature, we are seeing efforts to extend them with recursive semantics, applying diverse ideas from logic programming and description lo…
