Chapter 25 Controlling mapping to XML schemas - Mapping literal attributes to XML schemas

Map text attributes to XML pattern

This section discusses how to project literal (non-collection) properties to XML types, as well as options that affect the XML schema. It discusses the following:

• Default for data type classes XSD Type
• Compiler keywords that affect architecture
• Parameters that affect the architecture

IRIS Default for data type classes XSD Type

If the class or class attribute is based on one of the common IRIS data type classes, the XML type will be automatically set according to the following table. Classes in the %xsd package map directly to XML types, as shown in the table.

%Library sum %xsd package IRIS number arrangement type XM category type

IRIS Class in the %xsd Package	IRIS Class in the %Library Package	XSD Type Used in Projections to XML
%xsd.anyURI		anyURI
%xsd.base64Binary	%Binary，%Status	base64Binary
%xsd.boolean	%Boolean	boolean
%xsd.byte	%TinyInt	byte
%xsd.date	%Date	date
%xsd.dateTime	%PosixTime，%StringTimeStamp，%TimeStamp	dateTime
%xsd.decimal	%Currency，%Decimal，%Numeric	decimal
%xsd.double	%Double	double
%xsd.float		float
%xsd.hexBinary		hexBinary
%xsd.int		int
%xsd.integer		integer
%xsd.long	%BigIn，%Integer	long
%xsd.negativeInteger		negativeInteger
%xsd.nonNegativeInteger		nonNegativeInteger
%xsd.nonPositiveInteger		nonPositiveInteger
%xsd.positiveInteger		positiveInteger
%xsd.short	%SmallInt	short
%xsd.string	%Name，%String，%List	string
%xsd.time	%Time	time
%xsd.unsignedByte		unsignedByte
%xsd.unsignedInt		unsignedInt
%xsd.unsignedLong		unsignedLong
%xsd.unsignedShort		unsignedShort

For information about XML data types, see https://www.w3.org/TR/xmlschema-2/.

For example, consider the following class:

Class Schema.DataTypesDemo Extends (%RegisteredObject, %XML.Adaptor)
{
    
    

Parameter XMLTYPENAMESPACE="mytypes";

Property binaryprop As %xsd.base64Binary;

Property booleanprop As %Boolean;

Property dateprop As %Date;

Property datetimeprop As %TimeStamp;

Property decimalprop As %Numeric;

Property integerprop As %Integer;

Property stringprop As %String;

Property timeprop As %Time;

}

The structure of this class is as follows:

<?xml version="1.0" encoding="UTF-8"?>
<schema xmlns="http://www.w3.org/2001/XMLSchema" xmlns:s="http://www.w3.org/2001/XMLSchema" 
elementFormDefault="qualified" targetNamespace="mytypes">
  <complexType name="DataTypesDemo">
    <sequence>
      <element minOccurs="0" name="binaryprop" type="s:base64Binary"/>
      <element minOccurs="0" name="booleanprop" type="s:boolean"/>
      <element minOccurs="0" name="dateprop" type="s:date"/>
      <element minOccurs="0" name="datetimeprop" type="s:dateTime"/>
      <element minOccurs="0" name="decimalprop" type="s:decimal"/>
      <element minOccurs="0" name="integerprop" type="s:long"/>
      <element minOccurs="0" name="stringprop" type="s:string"/>
      <element minOccurs="0" name="timeprop" type="s:time"/>
    </sequence>
  </complexType>
</schema>
