This dictionary specifies the standard values for dataType, specified in the WCS 2.0 GML 3.2.1 application schema. This dataType is for values of a RangeField. In addition, this dictionary specifies definition URNs in the "ogc" URN namespace for these values. This dictionary uses a currently unspecified simple dictionary profile of GML 3.2.1. Definitions are compatible with XML Schema as of 28 October 2004 [http://www.w3.org/TR/2004/REC-xmlschema-2-20041028/]. Identifiers do not have an associated unit of measure.

DataTypeIdentifiers Logical value; admissible values are "true" and "false" (in whatever case), as well as 0 (which shall represent "false") and 1 (which shall represent "true"). boolean Positive or negative integer number without any limitation on maximum and minimum values. For expressing certain value range limitations the specialized types byte, shortInteger, int, and LongInteger are available. long Non-negative integer number without any limitation on minimum values. For expressing certain value range limitations the specialized types unsignedByte, unsignedShort, unsignedInt, and unsignedLong are available. unsignedInteger Positive or negative integer number with values between -128 anf 127. byte Non-negative integer number with values between 0 and 255. unsignedByte Positive or negative integer number with values between -32768 and 32767, which allows for a representation with 16 bits. short Non-negative integer number with values between 0 and 65535, which allows for a representation with 16 bits. unsignedShort Positive or negative integer number with values between -2147483648 and 2147483647, which allows for a representation with 32 bits. int Non-negative integer number with values between 0 and 4294967295, which allows for a representation with 32 bits. unsignedInt Positive or negative integer number with values between -9223372036854775808 and 9223372036854775807, which allows for a representation with 64 bits. long Non-negative integer number with values between 0 and 18446744073709551616, which allows for a representation with 64 bits. unsignedLong Single-precision floating point number according to IEEE 754-1985. double Double-precision floating point number according to IEEE 754-1985. double
