Our Vision for the Future
Later versions of the documents module will build on proposed new core features like:

• Workflow management and versioning.
• Visual "templates" that render the documents module in a variety of ways.
• User-defined fields. 
• File Icons "

Show me the metadata ;) how far is that future? In the meantime are there robust third-parties modules?

I must say I'm a bit puzzled to see DotNetNuke referred to, more and more as a "Content Management System", shifting from the "Web Application Framework" ealier labeling. Unless I'm missing something from the Document module, or perhaps CMS functionality is elsewhere, but a very basic expectation for a "CMS" is to be able to upload content like for example a .pdf or .doc AND assign metadata to it, other than just a title and a trickle of other fields?

Any hint, or third-party module recommendation welcome. Thanks!
