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…

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…
Shape Expressions Schemas
