how to render custom layout of the projection of known content items
===

I have defined my own projection by a query which returns a set of content items of known content type. I would like to take pick up certain content parts of these content items and display them in the list. Using shape tracing tool I have found the view template where to write my custom layout:
*/Views/Parts.ProjectionPart.cshtml*

but from the Model variable in the template I can not get the data I want because it is way too high above from the content parts data. 

a good example of what I want: let's say I want to render product catalog as defined in this tutorial:
http://skywalkersoftwaredevelopment.net/blog/writing-an-orchard-webshop-module-from-scratch-part-5

but I want only to render a list which consists from items:
 

 1. name of the owner who created the product  
 2. name of the product. 
 3. publish date of the product

and I need to render it at one place, i.e., not separately in their own part views.
