[Psidev-ms-dev] RE: Element vs. complexType - mzData schema issue with WSDL using RPC style

[Shawn H. <sh...@xt...>]

Hi Kent,

Thanks for your quick reply. I have some prototype WSDLs generated for
both document and rpc styles using mzData. Please let me know if you
like to take a look at them.

Thanks,
Shawn

Shawn,

Thank you.  You are correct, and this will be added into our
requirements set.  The need for mzData to fit into the SOA and Grid
worlds has become poignant is recent months.

Subject: Element vs. complexType - mzData schema issue with WSDL using
RPC style

The following issue is based on an assumption that mzData supports Web
service definition (WSDL) for mass spec data transaction.=20

After some testing on WSDLs using mzData.xsd, I found an issue with the
schema regarding its root element. It seems that the current mzData.xsd
does not support WSDL rpc message style.=20

There are two SOAP message styles defined in W3C WSDL specifications:
"document" and "rpc". Basically if a WSDL is defined for a "document"
style, a schema element should be specified. However if a WSDL is
defined for "rpc" style, a schema complexType should be provided.=20

The current schema can only be used for "document" style Web service
since it only has a root element but no global complexType for the root:

<xs:element name=3D"mzData">
	<xs:complexType>
	....

In order to use the schema for both "document" and "rpc" styles, the
root element is better to be defined as:

<xs:element name=3D"mzData" type=3D"mzDataType"/> <xs:complexType
name=3D"mzDataType">
	....
</xs:complexType>


The syntax of the related WSDL definition is listed below:=20

*	Document message:	use <element> in <message>
	<wsdl:message>
		<wsdl:part name=3D".." element =3D"g1:mzData">
	<wsdl:message>

*	RPC message:		use <type> in <message>
	<wsdl:message>
		<wsdl:part name=3D".." type =3D"g1:mzDataType..">
	<wsdl:message>

Note: g1 is a prefix of the mzData targetNamespace.


Thanks,
Shawn
