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.

UsePlainGraph

public static boolean UsePlainGraph

Use a plain graph (sameValueAs is term equality)
