Re: [syndication] Simple Semantics Resolution - RSS 2.0 Module

[Mark Nottingham <mnot@mnot.net>]

I disagree. Having an everything-in-one approach is difficult to 
support, and needlessly complex. If there's a need to describe other 
kinds of mappings, just come up with corresponding RSS modules.

Also, XSLT is a more neutral language; something like Python, despite 
being cross-platform, is more prone to the variegates of local 
installation, versioning, module availability, etc.

That said, it would be better if the chosen language were more 
declarative; my hobby horse has been adding hints to XML Schema so that 
you can extract statements from instance documents [1], but it hasn't 
caught on yet.

Cheers,
