Peace!

I’am trying to code a ‘litle’ music enviroment… huh, dunno how to  
call.  
I want to import a large amount of files(30k+) into a database and tag  
each  
of them.

After a import i get objects for each directory (first only  
directories), with some variables  
(@rel referes to the parent directory node).  
It looks like this: [1]

I want to save each of those objects somehow nice (first only the tags:  
‘category’, ‘bitrate’, ‘path’)…  
After the intial import, i want to extend the tags.  
Later there are many tags, many files with compley queries  
so i get now a bit scared to save all in a directory tree.

Maybe anybody has an better idea?

ID:DIR\_LVL::name

[1] (human eye obj.inspect)

- 00025:3::the streets - mixtape {
- (@rel =

00022:2::the streets {

    00021:1::garage {

        00000:0::root {

          (@name = root );

          (@path = /mnt/hdd/music );
