Declaring Namespaces

You must declare these namespaces in a mashup script:

Namespaces used in component mashable information sources.

Note:

When you declare namespaces for component mashables, you must use the same namespace prefix as the MashZone NextGen Server.

Namespaces used in the construction of input parameters, output parameters or variables.

The macro reference namespace for any custom statements (macros) that you use in your mashup. See Calling a Macro for more information.

The EMML namespace and the MashZone NextGen EMML Extension namespace.

Note:

See EMML Namespaces for the currently supported namespaces for EMML and macros.

You declare namespaces using the xmlns attribute on any element in a mashup script. Typically, it is easier to define all the namespaces used in the script on the <mashup> element. For macros, especially in a macro library, it is a good practice to define namespaces on <macro>.

This example shows <mashup> with the default namespaceDe set to EMML:

It has two additional namespace declarations, for Atom and XHTML, that are used in the <constructor> statement to build the body of a <directinvoke> that posts to a blogging service. Namespaces are simply valid URIs - they can be URLs or URNs.

Note:

Previous releases used <namespace> elements to define namespace for component mashables. This technique is deprecated, although it is still supported.
