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…
PG-Schema: Schemas for Property Graphs
Renzo Angles, Angela Bonifati, Stefania Dumbrava +18
Property graphs have reached a high level of maturity, witnessed by multiple robust graph database systems as well as the ongoing ISO standardization effort aiming at creating a ne…
Inference of Shape Expression Schemas Typed RDF Graphs
Benoît Groz, Aurélien Lemay, Sławek Staworko +1
We consider the problem of constructing a Shape Expression Schema (ShEx) that describes the structure of a given input RDF graph. We employ the framework of grammatical inference,…
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…
Relational to RDF Data Exchange in Presence of a Shape Expression Schema
Iovka Boneva, Jose Lozano, Sławek Staworko
We study the relational to RDF data exchange problem, where the tar- get constraints are specified using Shape Expression schema (ShEx). We investi- gate two fundamental problems:…
Shape Expressions Schemas
Iovka Boneva, Jose E. Labra Gayo, Eric G. Prud'hommeaux +1
We present Shape Expressions (ShEx), an expressive schema language for RDF designed to provide a high-level, user friendly syntax with intuitive semantics. ShEx allows to describe…
