XML by Example

Creating a Sensible URL

There are no rules on how to build URLs for namespaces. As long as it has

the right format (as explained before), it works. Experience shows that

URLs works best if they follow the following rules:

• Namespaces are identified by Web addresses. You might want to post

a description of the namespace at a later point.

• The URL is reasonably short to save typing.

• The URL includes a readable description of the namespace.

• The URL includes a version number so you can update the namespace

by changing the version number.

Some examples include

http://www.psol.com/xml/address/1.0

http://www.w3.org/XSL/Transform/1.0
