Part a

The dataset contains some superhero moviedata from IMDB! We want to use this data in our system to play around with movie ratings. To this end we want to make sure the ratings are using the correct datatype!

Extend the following shape to check that that all movies have a rating and that all ratings are typed as xsd:decimal.

Shapes:

@prefix schema: <http://schema.org/> .
@prefix sh: <http://www.w3.org/ns/shacl#> .
@prefix xsd: <http://www.w3.org/2001/XMLSchema#> .
@prefix : <http://data.superheros.com/id/superhero/> .

:MovieList a sh:NodeShape ;
  #- insert here -#
.

Fix any data violations!

Part b

We're organizing a Superman movie marathon. But we only want to watch movies with the original actor: Christopher Reeve.

Make a shape that describes those movies! Are there any movies that don't make the list?

Shapes:

@prefix schema: <http://schema.org/> .
@prefix sh: <http://www.w3.org/ns/shacl#> .
@prefix xsd: <http://www.w3.org/2001/XMLSchema#> .
@prefix : <http://data.superheros.com/id/superhero/> .
