Comparing RQL to W3C XQuery
XML syntactic and schematic discrepancies of semantically equivalent RDF statements
- normalized representation under the form of merged descriptions
-
XQuery has no built-in knowledge of the RDF schema information
- function library that exploits the RDF schema if the assertions of the schema are also present in the normalized representation
-
Data model mismatches between XML and RDF impact type safety of functions and queries
- bag( range(Artist) ) union subclassof(Artifact)
- In RQL Type Error
- In XQuery All the subclasses of Artifact !
