Description
When parts of the Oslo municipality decided to change to a semantic platform using RDF as a standard for the data, a need for data validation soon became apparent. Could we really trust the data we were working with? This talk shares experiences of two different projects using Shape Constraint Language (SHACL) for data validation, including a brief introduction to the constraint language.

At both projects we implemented our own SHACL engines. Although we used different approaches when implementing the engines, both used data converted from non-RDF and are written in Java using RDF4J. SHACL provided us with an easy-to-read validation tool with closed world assumption that produced a more consistent data model with higher data integrity.

No prior knowledge of semantic technologies or RDF is needed, as this is covered at the beginning of the talk.
