TYPO3 should provide built-in support for the "canoncial" tag which was recently introduced by various search engine providers (see links below).

There is a way by adding it with TS. Perhaps you could test it along some instalations. I think it works great this way. What do you think?
lib.meta.canonical = COA
10 < config.baseUrl
wrap = |/
20 = TEXT
parameter.data = TSFE:id
returnLast = url
wrap = <link rel="canonical" href="|"/>
required = 1

I did not try but tend to say that this is a wrong attempt.
The canonical URL of every page output type must be the same (print-page, PDF output, RSS feed, HTML, etc.) - as far as I see this is not considered by the above attempt.
However, it could be even more advanced. Say you have a table that lists records, and you can sort it in different ways, then also these pages should all have the same canonical URL.

Ok, good points. Didn't thought of the more complex scenarios.
I'm sure that you can tweak it more with TS so it fits the special needs of each specific site. But out of the box this would be a nice feature.
I think the best solution would be to let you define the parameters that are allowed to change or generate this URL.
.allowedParams = id,tt_news[cat],L
Actually i don't know how to make this possible but perhaps someone else. ^^

I found a really good snippet at http://blog.marit.ag/2009/02/23/canonical-tag-fur-die-suchmaschinen/
What do you think of this approach? I think this is the more advanced version of my previous snippet.

A table with top 100 movies has a different meaning than a table with worst 100 movies. Although it is the same data (movies + rating) just sorted in a opposite order, I'd say this is two different aspects which should be expressed with two URIs.
What's the matter? We should keep in mind to leave this decision to the admin and give him the power of configuration.
