Two Step View Presentation Pattern

I'm looking for more information the Two Step View pattern for web
presentation. Maybe some implementations or example, etc. I'm trying
to get ideas on where the best places are to implemented things.
Mostly menus and the like. Thanks for any help, much appreciated.

That's a great site, for sure. Nothing specific I can find on
architectural patterns. Thanks for pointing me to that though!

I guess the specifics I'm trying to find deal mostly with menus and
the Two Step View Pattern. If I receive the domain data in XML form
from the first step, then the second step will add the appropriate
appearance, where do I add in site navigation that may be dependant up
the domain data. While I'm trying to keep the navigation consistent
(mentioned a lot on that usability) some cases require specific sub
menus.

If I place the added data for the menus in at the Business
Logic/Facade layer, then the site layout is tied all the way down to
the subsystems, not good. If I try to place these different
navigation elements in the second step, there will be an abundance of
crazy xslt to base navigation on data it receives.

The first step just transforms the data into xml, leaving out
irrelevant parts, I don't know how or if it would be a good idea to
place navigation information in this step. Seems about one of my last
choices by process of elimination.

I've debated adding in another step to deal with this, but I'm trying
to reduce complexity from the current 60+ xslt sheets with logic and
presentation smashed into one.

I hope that makes sense... Working on my architectural vocabulary.

Thanks,
Matt.

There is a section on this design pattern in Martin Fowler's Patterns of
Enterprise Application Architecture.
