namespace clarification ...!

[Former Member]

Hi Experts ,

I have a question regarding the namespace ...is there any specific reason why we have namespace with extension

for ex : urn:xxx-com.xi:data:xxx

http://xxx.com.xi/abc/ECC

why are we using urn and http and is there any specific diffrence between urn and http kindly let me know .

Regards,

Hi Aziz,

http:// is used when you specify an HTTP address as a namespace this does not mean that you can access additional information about the namespace from this address (in some cases an XML schema definition is hidden behind the address). The HTTP address used merely ensures that the name of the namespace is unique. SAP namespaces adhere to the standard http://sap.com/xi/<Name>.

urn is used when the Namespaces with this prefix have no value in the sense that they are not connected with a Web page in the Internet.

Thanks,

Hi Aziz,

According to my knowledge XML namespaces starts with HTTP or URN thats why we use the same in PI.

HTTP is used at protocol assignment like web service, Http,..

URN is used for non protocol assignment like JDBC,..
