XML Namespace question

[bfrederi]

How do I create an XML namespace?

Say I have one defined in my root element: xmlns:namespacename="http://
theurigoeshere.com/xmlnamespace"
How do I get that http://theurigoeshere.com/xmlnamespace to resolve
like this one does: http://purl.org/dc/elements/1.1/
I know there is a way that the uri will return the actual name of the
namespace, but how?

I am not sure what you are asking about. URI used for namespace do not
need to point to an actual resource. URIs are simply used to have unique
names. In the example
<pf:root xmlns:pf="http://example.com/2008/ns1">
the namespace name is http://example.com/2008/ns1 and pf is a prefix
bound to that name.

That deends what you mean by "create".

You put something on the webserver for the URI in question.

But you don't usually have to do this to use a namespace. For
example, a schema validator may try to open the URI to find a schema,
but there will be an alternative way to provide the schema directly.

I don't understand this question. The URI *is* the name of the
namespace.

An XML namespace identifier is basically a string. However, by
convention it is done in the form of an HTTP URI (http://...). Even
if you make it an HTTP URI though, that doesn't mean that the URI has
to resolve to a real web page!

Say I have one defined in my root element: xmlns:namespacename="http://
theurigoeshere.com/xmlnamespace"

Just put up a web page and serve what ever you think's appropriate in
the normal way - or not as the case may be!

I guess I should be more specific in what I am doing. I am using
ElementTree in python, and when I add the dublin core namespace
"http://purl.org/dc/elements/1.1/" to my elements when creating my
XML, it automatically knows that the uri "http://purl.org/dc/elements/
1.1/" is supposed to be known as "dc". So it automatically add this to
my root element: xmlns:dc="http://purl.org/dc/elements/1.1/" and to
all the of elements I have attached the uri "http://purl.org/dc/
elements/1.1/" to, it puts a "dc:element" for the element name. So
somehow the uri is able to resolve to an alias of "dc". How do I
create my own uri that will resolve as such? Do I need to create some
sort of reference file that does something of the effect of namespace
= "http://www.example.com/namespace/" or is it an apache setting, etc?

The prefix chosen doesn't matter. If the tool has promised it will take
care of this, it's the tool's responsibility (more accurately, the XML
Serializer's responsibility) to either generate or select an appropriate
prefix and bind it correctly, or to use default namespaces, or both,
when it writes out the XML. The DOM Level 3 spec describes one way this
can be done, but the precise algorithm doesn't matter as long as
everything winds up bound to the right namespace URI.

I haven't used that Python tool, so I don't know what approach it's
using. Check with whoever authored that tool?
