If I understand right, you're talking selection/sorting here.

In Cocoon itself, you could use XSLT transforms to do these selections and 
sorts, but to get good performance you'd need to prepare some kind of "map 
files" in XML that would contain lists of directories or file names, mapped 
to project identifiers.

Depending on the number of documents and directories and on the frequency of 
updates, this could quickly become too slow or impractical, at which point 
you will need some kind of database (XML or relational) to hold these maps. 

This kind of "file attributes database" is not a standard part of Cocoon 
today AFAIK, you'd have to build it yourself or use external components for 

What Cocoon offers today is easy access to SQL databases and good integration 
with the XIndice XML database. There have been talks recently on cocoon-dev 
about using the Slide content management system as a back-end, but it's not 
there yet.

If this means filtering XML documents and converting to presentation formats 
(HTML, PDF, RTF, etc.), then yes, that's exactly what Cocoon does.

Hope this helps!
