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…
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:…
Validating and describing linked data portals using shapes
Jose-Emilio Labra-Gayo, Eric Prud'hommeaux, Harold Solbrig +1
Linked data portals need to be able to advertise and describe the structure of their content. A sufficiently expressive and intuitive schema language will allow portals to communic…
