Document library – with image examples

Hi there,

I know several people in the past have asked about document libraries, modifying Media Library for pdf and .doc files, etc, but they tend to go unanswered, I am assuming because there is no single plugin to do what people need. So here is a request to find plugins to do the individual things that I’m trying to accomplish:

Overview

Create a document library that allows for

• easy categorization and display (I can use the built in categories system as described here, but would prefer an explorer style tree structure)
• Multiple categories per post (internal WP system is fine)
• Independence of search from the main blog so that I can find only articles in the document library (a search box that requires a custom field perhaps?)
• Ratings for individual posts/articles
• Display of views/comments in the search area
• weighted tag clouds
• Tag searches
• Embed docstoc or scribd PDF or doc files

Details
See images here and here for quick and to the point details.
(note: on the second image, ratings should not have disappeared)
These images are taken from the vivvo.net CMS plugin section, for reference

Where help is needed
I don’t know what plugins would work best for:
Ratings
Tagging
Search
Tree navigation

I’m also not sure what would be better as a template modification or as a plugin, so if anyone could help clarify, that would be greatly appreciated.

Thanks so much for your time, hopefully we can find a way to build this document library, together!
