  • Field Details

    • ValueExtensions

      public static boolean ValueExtensions
      Control whether addition datatypes, over and above strict, minimal SPARQL compliance, are handled. Examples include xsd:date and simple literal/xsd:string.

    • StrictDateTimeFO

      public static boolean StrictDateTimeFO
      Under strict F&O, dateTimes and dates that have no timezone have one magically applied. This default timezone is implementation dependent and can lead to different answers to queries depending on the timezone. Normally, ARQ uses XMLSchema dateTime comparisons, which an yield "indeterminate", which in turn is an evaluation error. F&O insists on true/false and so can lead to false positives and negatives.

    • EnableRomanNumerals

      public static boolean EnableRomanNumerals
      Whether support for Roman numerals (datatype http://rome.example.org/Numeral). Mainly a test of datatype extension.

    • EnableCDTs

      public static boolean EnableCDTs
      Enable CDT support. SPARQL CDTs: Representing and Querying Lists and Maps as RDF Literals
