Best Practice: Use of RDF data types
State: Draft Contact: Nick CrossleyScope
This Best Practice recommends appropriate usage of RDF data types, and considers the implications for query writers.Discussion
- An untyped literal (in Turtle, a literal in quotes) is the same as xsd:string
- In Turtle, unquoted literals have an implicit type - true is the same as "'true"^^xsd:boolean, 42 is the same as "42"^^xsd:int, etc.
- Comparison of typed literals varies between SPARQL implementations
- xsd literals and type hierarchy
- user-defined types extending xsd literals
- other user-defined types
- Types used by OSLC
- Jena performs very strict validation of the contents of literals with type XMLLiteral
