[Geoserver-users] Trying to understand Namespace URI?

[epyks23]

What is Namespace URI when creating a workspace? What is the purpose of them?

Would this be correct to use: http://localhost:8080/geoserver

Is it different if I am hosting my layers globally? Does the URI have to be
different?

epyks23,

the namespace URI is the XML namespace for types (layers) defined within
a workspace:
https://en.wikipedia.org/wiki/XML_namespace

If you publish a layer globally, choose a namespace that is unique to
you. For example, one that is an HTTP URI for a domain you own. Note
that I wrote URI, not URL: the namespace does not have to be resolvable
as it is just an identifier (but it might be convenient if it is). Aim
for a namespace URI that will never change.

Namespaces allow types to be defined with the same name but with
different definitions. For example, a government agency might have a
type Tree and use it to publish information on who owns a tree and
whether it is protected from felling:

Namespace URI: http://example.org/government Feature Type: Tree

A biologist may define a Tree by its species and relationship to other
living things around it:

Namespace URI: http://example.org/biology Feature Type: Tree

Using different namespaces allow both to publish their own Tree type
with different properties without confusion. Specialist communities
agree on namespaces to enable interoperability. For example, GML 3.1,
GML 3.2, and WFS 1.1, and WFS 2.0 each have their own namespaces.

The workspace name is used as the default XML namespace prefix for that
namespace; the prefix is just a short convenient alias. Strict
compliance to OGC Web Service standards requires each namespace prefix
to be associated with its namespace URI in every request, but GeoServer
lets you use a namespace prefix matching a workspace name without having
to define it in a request. XML namespace prefixes are not unique across
services and are local to XML instance documents.

Kind regards,
Ben.
