fix: handling of rdf:HTML literals by aucampia · Pull Request #2490 · RDFLib/rdflib (original) (raw)

Summary of changes

Previously, if without html5lib installed, literals withrdf:HTML datatypes were treated as
ill-typed, even if they were not ill-typed.

With this change, if html5lib is not installed, literals with the rdf:HTML datatype will not be treated as ill-typed, and will have Null as their ill_typed attribute value, which means that it is unknown whether they are ill-typed or not.

This change also fixes the mapping from rdf:HTML literal values to lexical forms.

Other changes:

• Add tests for rdflib.NORMALIZE_LITERALS to ensure it behaves correctly.

Related issues:

• Fixes Casting literal with content to rdf:HTML datatype leads incorrectly to empty literal #2475
