      • 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 with 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 comparions, which an yield "indeterminate", which in turn is an evaluation error. F&O insists on true/false and so can lead to false positves and negatives.

      • EnableRomanNumerals

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

      • UsePlainGraph

        public static boolean UsePlainGraph
        Use a plain graph (sameValueAs is term equality)
