Hm.. that looks more like what I had in mind when I posted, but allso quite a
bit more overhead than rewriterules.
At least for me that has never written a product.
I will have to think about that one..
Would you care to elaborate a little bit on what the tradeoffs would be?
If I wanted my articles in many variants, ie. a large state space, I guess
this way would be good?

Well, it may feel like a lot of work to you the first time :-)

My approach might be good if:
- the logic for looking up articles is more complex than can be
comfortably expressed using apache rewrite rules, and/or
- the logic for looking up articles requires state that's internal to zope.
You could instead follow Andreas' suggestion and use a through-the-web
Script. It might look something like:
article_id = traverse_subpath[-1]
data = context.get_the_data_somehow(article_id)
return data
Your URLs would then look like:
http://example.com/folder_id/script_id/article_id
Note that naming the script index_html doesn't really help, because
http://example.com/folder_id/article_id wouldn't invoke the script.

[Zope] How to get REST friendly urls from sql database
Hi. Normally a url to an article in our CMS system would look roughly like this: http://www.dom.tld/aritcles/25245 Where 25245 would be an object of some metatype, say 'article'. Now what if I wanted to get the data for that page from an sql server instead, I would expect to end up with a url like this: http://www.dom.tld/aritcles/index_html?id=25245 Now, having recently read the Roy Fielding paper, and expecting to do some caching, I would much prefer to have it the first way, even when I have to get the data out of a DB.
