Personal Namespace Extension
Extension: Personal Namespace Extension
Purpose: The RSS specification allows
you to create and use your own custom elements
(tags) in any RSS feed, by declaring your
own namespace. Doing this is 100% in line
with the RSS specification and the feed will
validate. However, you should have a specific
and well-planned reason to do so. No RSS readers,
or other RSS processing applications will
be able to use your custom info for any purpose.
Adding elements (tags) would typically only
be used in an in-house solution where the
writing application and the reading application
have prior knowledge of the new tags.
Declaration: First you will want to
create a namespace declaration for your new
custom namespace. In FFA, go to the 'Feeds'
tab, and then to the 'Extensions' tab. Hit
the '+' button to bring up the 'Add Namespace
Declaration' screen. Enter a name for your
namespace (typically a short abbreviation),
and a DTD URL. The DTD URL must be a valid
URL, but it doesn't really matter what webpage
it points to.
It must be unique from all the other namespace
DTD URLs, but a valid DTD document at that
location, is not required. The RSS specification
does not require a valid DTD document to exist,
for the namespace declaration to be valid.
What is important is that the namespace name
and DTD url be unique. After you accept your
changes (the check mark button), a new tab
will appear under the 'Extensions' tab for
the feed, image, and all your items.
Because the new namespace is not recognized
as a 'well supported' namespace by FFA, you
will be required to enter raw XML in your
new namespace tabs, with the data you wish
to use. At this point you can pretty much
make up the tag names you want to use (prefixed
with your namespace name and a colon). Just
make sure you use valid XML syntax (ie. close
the tags you open, etc.) For example, if I
wanted to create a new namespace for our in-house
use here, I might to something like this:
Namespace Name: ffa
Namespace DTD URL: http://www.feedforall.com/ffa-dtd/
Sample XML in new ffa extension tab:
<rss version="2.0" xmlns:ffa="http://www.feedforall.com/ffa-dtd/
">
Elements: Sample date addition to namespace
Example:
<ffa:BirthDate>02/02/1992</ffa:BirthDate>
