Projecting Objects to XML

You can map InterSystems IRIS objects to XML by extending classes with %XML.Adaptor. This enables the projection of object properties, collections, and relationships into configurable XML elements and attributes for web service data exchange.

XML projection in InterSystems IRIS is the process of translating class instances into XML documents. You need it when integrating internal application data with external systems or SOAP web services that require universally compatible XML data formats.

Yes, you can control property naming, structure, and namespaces when serializing IRIS objects to XML. The mapping uses configurable options like XMLPROJECTION, XMLSUMMARY, and XMLFORMAT to define exactly how class properties translate to XML elements and attributes.

Yes, InterSystems IRIS supports importing data from XML back into objects. The object projection mechanism facilitates both data export to XML and import from XML, handling both literal and encoded formats for web service integration.

The best way to handle complex relationships and collections in XML serialization is by extending classes with %XML.Adaptor. This mechanism manages the mapping of nested object properties, collections, and relationships directly to structured XML elements.

Use XMLPROJECTION to control how individual class properties map to XML elements or attributes, and XMLSUMMARY to define summarized representations of objects. Both are configurable options available when extending classes with %XML.Adaptor for customized XML output.
