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…
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…
Shape Expressions with Inheritance
Iovka Boneva, Jose Emilio Labra Gayo, Eric Prud'hommeaux +2
We formally introduce an inheritance mechanism for the Shape Expressions language (ShEx). It is inspired by inheritance in object-oriented programming languages, and provides simil…
Static Analysis of Graph Database Transformations
Iovka Boneva, Benoit Groz, Jan Hidders +2
We investigate graph transformations, defined using Datalog-like rules based on acyclic conjunctive two-way regular path queries (acyclic C2RPQs), and we study two fundamental stat…
Consistency and Certain Answers in Relational to RDF Data Exchange with Shape Constraints
Iovka Boneva, Jose Lozano, Sławek Staworko
We investigate the data exchange from relational databases to RDF graphs inspired by R2RML with the addition of target shape schemas. We study the problems of consistency i.e., che…
Semi Automatic Construction of ShEx and SHACL Schemas
Iovka Boneva, Jérémie Dusart, Daniel Fernández Álvarez +1
We present a method for the construction of SHACL or ShEx constraints for an existing RDF dataset. It has two components that are used conjointly: an algorithm for automatic schema…
