[O] Keeping metadata/notes about files and directories

[Christoph Groth]

Dear all,

I just wrote under the subject “Re: Managing articles in org mode 
and collaboration”.  This posting puts the other one in a broader 
context.

While thinking about organizing articles, I asked myself: Wouldn’t 
it be useful to keep metadata/notes about *various* kinds of 
files/sub-directories/projects inside org-mode (or something 
similar)?

One example is a collection of programming projects.  Just like 
for articles, it would be useful to add notes and metadata to each 
project.  The same is true for many other archive-like collections 
of things that grow over time.  The same problems appear as 
described in the other posting (namely scaling and searching).

I know that there have been discussions about this in the past, 
and I know that there’s org-annotate-file.  Is there anyone who 
uses a scheme like this (for >1000 items, say) in practice?
