>While the building blocks of the Jabber protocol, described in
<A
HREF="c3612.htm"
>Chapter 5</A
>, provide the groundwork for our solutions,
for our chess rules, there's still something missing. </P
><P
>There's a purity and elegance that's to be had with usage of the
three core elements <TT
CLASS="LITERAL"
><message/></TT
>,
<TT
CLASS="LITERAL"
><presence/></TT
>, and
<TT
CLASS="LITERAL"
><iq/></TT
>, but there's a depth of
meaning that's missing. While the core elements define the moves
we can make, it's the Jabber <I
CLASS="EMPHASIS"
>namespaces</I
> that
provide us with the contextual set-moves that allow us to relate
Jabber to the real world.</P
><P
>Namespaces provide a level of meaning, an environmental
layer, above the basic "packet shunting" world that would
otherwise exist if our elements were to be passed back and
forth bereft of context and application.</P
><P
>Basic activities like user registration, authentication, roster
management, and time stamping are all made possible using meaning
brought about by the application of standard Jabber namespaces to
our elements.</P
><P
>This Chapter describes those namespaces.</P
