Note: This story was not about constraints, but described a solution to the "different shapes in different contexts" scenario.

This is an example of very complex constraints that require many features that are present in SPARQL to represent model-specific scenarios, including the comparison of incoming values against a controlled fact base, transformations from literal values to URIs, string operations, date comparisons etc.

Details: EPIM Reporting Hub SPIN was used to represent and evaluate those constraints.

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.
