ShEx Data Validation Demo

basic
- object datatype: pass fail
- cardinality: pass fail
- choices (exclusive or): pass fail
- value sets: pass fail
- nested shapes: pass fail
- named shapes: pass
- annotated issue example
- node fulfilling multiple shapes, with remaining triples (demonstrates graph coverage)
inheritance/polymorphism
- basic inheritance factor our commonalities
- virtual base sanitizes type-finding (without VIRTUAL you get uninteresting matches)
- issue with base person shape
controls
- blank node highlighting Entries in the select list under Validation: highlight the corresponding terms in the data.
- extra triples: open shape (highlights "fringe") closed shape (fails match)
features
- recursive pattern: foaf:knows/foaf:knows
- remote query: DBPedia German cities (select Data: Load/Query and then and )
- wikidata validation
Semantic Actions
- validation:
  - comparing dates: action on the triple or group or shape
- generation:
  - GenX Issue example
  - GenJ Issue example
- parsing:
  - ShExC for SHACL
domain-specific
- (simplified) FHIR Medication: pass fail
