Difference Between EAI Converters - 2

In continuation to my previous blog to understand the IO, Property set and XML mapping, I am sharing one of the examples oracle has provided.

Let’s draw a table to identify the difference between the converters mentioned in previous blog:

Feature	EAI XML Converter	EAI IO To XML   Hierarchy Converter	XML Hierarchy Converter	XML Converter
Input/Internal Representation	Siebel Message (Integration Object Instance)	Siebel Message (Integration Object Instance)	XML Hierarchy	Property Set Hierarchy
Output/External   Representation	XML Document	XML Hierarchy	XML Document	XML Document
Metadata/Rules	Integration Object Definition	Integration Object Definition	Translation Rules	Translation Rules(Optional)

Let’s discuss each one of them in detail:

Figure below explains the simple workflow being used to send the xml message from Siebel to External System.

EAI XML Converter

Converts the output of the EAI Siebel Adapter business service to an XML document or the other way round . It should be used whenever integration object definition is available.EAI XML Converter understands the Siebel Envelope and validates the data against the IO.

EAI Integration Object to XML Hierarchy Converter.

This business service is used to convert  the Siebel message/IO message to XML Hierarchy message  or from Siebel message to PSHierarchy Message and vice versa.

XML Hierarchy Converter 

This does not use integration object definitions. It expects  input property sets of type  "XMLHierarchy". It can have child property set of type "ProcessingInstructions" to tell the XML Hierarchy Converter what to do along with actual message.

The XML Hierarchy Converter is typically used for conversion from/to XML documents that do not have a relation to integration objects nor the typical Siebel Message envelope.

XML Converter 

It does not use integration objects nor does it expect/set the type of the input/output property sets. It simply converts an XML document into a property set and vice versa.
