Rss-Data and RSS 2.0 Extensibility
Note: this entry has moved.
I completely agree with Dare points. My comment on his weblog was:
I believe extensions through namespaces is a great
addition to RSS 2.0, but one that was also possible with
the W3C RSS 1.0...
I imagine an extensible plug-in architecture that would
load plugins from URL-retrievable namespaces (that would
be a convention, of course, such as
"http://danielcazzulino.com.ar/rss/metadata"), and that
would participate in the item's rendering process, either
server-side or client-side in a news aggregator. The
returned plug-in would have to conform to some interface
and would be readily downloaded and executed (CAS approval
assumed...).
For the server-side, I even imagine an Accept HTTP header
that would tell it whether the client requesting the RSS
feed supports a certain feature, for example, Accept:
x-include. If such a header was not present, the server
could pre-accumulate the XInclude-d fragments from other
sources.
