In principle there is no difference, but in practise most applications use http namespaces, so I recommend to go for this.

If you want to use Java proxies, then avoid urn namespaces, as package names are not related from urn namespaces correctly.

Hi,

Namespaces in the Integration Builder are namespaces in the sense of XML namespaces that are sub-divided further into semantic units within the Integration Builder software component versions. Objects of a namespace can only be shipped as part of the corresponding software component version and not separately.

Each object for a namespace has a unique name within this namespace. An object is

identified uniquely by a namespace + object name.Basically, a namespace in XML can be any constant value. Note the following two

conventions:

http:// 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: Namespaces with this prefix have no value in the sense that they are not

connected with a web page in the Internet.

For Both http & urn there is limitation of Char 60 max.The namespace is to avoid the naming conflicts, so I am doubtful if you have to perticularly used it for any other requirment as more than 60 Chars

Thanks

Hi

As You seem to know a bit more about namespaces in XI... I have situation where external systems use longer namespaces (long namespace names are not my made up by myself!). This is really painful to create a workaround (using XSL mappings) as all the namespaces are just a little longer than 60 characters.

I could understand a limitation of 1024 characters (URL maximum length) but 60 character limit is strange.

So the question remains. What to do if there is a need for using longer namespaces than 60 characters?

Best wishes,

Heiko
