[Sigia-l] IA friendly content management systems? Recommendation needed.

[Stewart Dean]

Hi,

I'd like to tap into your group experience. I know there are so many CMS 
systems out there for various costs and promise different things, so I'm 
expecting many different responses.

I would be very grateful if people could recommend commercial CMS systems 
that they feel are user friendly, simple yet powerful and are IA friendly.  
This is partly for myself and also as a reommendation for a project I am 
working on.

Key things it needs to do.

Manage articles and pages.
Be web based.
Allow workflow creation with eidtors and content authors with audit trail.
Allow versioning and roll back.
Have asset management built in (for pictures, attachments and also for the 
articles).
Have breadcrumbs, sitemaps, search and all the usual things built in and 
easy to set up.
Friendly urls and static publishing (dynamic only systems with garbage urls 
are out).
Be able to produce triple AAA complient sites - XHTML etc.
Seach engine friendly.
Provide checking of urls to ensure no dead links.
Articles can be timed to go live and a best before date.
Easy site structure management with automatic navigation updating.

Also all the usual stuff like meta tagging, multiple templates, Word 
importing etc.

I would have thought all this stuff is fairly standard but I'm amazed that 
many systems have no way to manage site structure or have no sepeartion 
between articles and pages or require ninja programming skills to get it do 
basic things like bread crumbs.

Overy specialised CMS systems, like blogging or enterprise systems I'm not 
interested in as they tend to be overly complicated and cannot deliver on 
how I architect sites - I really don't want to have to change how I envision 
the site working because the CMS can't do x or y.

So - with all that in mind - does such a CMS exist?  Is there a good solid 
fully capable CMS that has a good interface and workflow?

Thanks for any advice in advice.
