Validating stories updating local policy with regedit

Often the intention is to state that a given property shall only have IRIs but not Blank Nodes.

Two examples from the VOID namespace, void:data Dump and void:example Resource declare an rdfs:range of rdfs: Resource, but the intention is to only support IRI resources.

Only if the constraints were not violated would the tool actually be run.

The constraints would be separate from the ontology involved, as other uses of the same ontology would not necessarily have the requirement that all instances of person have their names specified.

When OK is pressed, a server callback is made to verify all if constraints have been violated.

If violations exist, they are presented to the user and depending on the severity and server settings, the user may continue without fixing the errors.

There is a need for access rules on what operators can see what data from what oil and gas fields, and for complex constraints to run during import of XML files.User-defined SPIN functions were used to make those complex queries maintainable.Note: This story was not about constraints, but described a solution to the "different shapes in different contexts" scenario.The foaf: Document case is interesting, shows that people might want to specify both the value’s class (foaf: Document) and node type (URI only).SPARQL includes the built-ins is IRI, is Blank, is Literal for those checks.
