Navigation != Presentation
BrowseGoods (via elAbra, via dirk) presents the same navigation model than an usual e-commerce shopping, but, with a different presentation approach.
For both cases the Navigation Model should look like a traditional hierarchy composed of menus and indexes of goods. But this time, it is presented in an only zoom-in-out control, instead of using traditional controls as does -for example- Amazon (i.e. menus, grids, search boxes, etc.).
The Navigation Model exposes the navigation paths the user have to follow to reach each concept; the Presentation Model just defines where and when render each concept and specifies which control to use for each case.
It can be a good example to show the power of the separation of concerns exposed in the Himalia's meta-model (that was taken from older hypermedia methods). I will add it to our Mingle.
