Another quick question :)
Are the rules for creating a download url from the "file" tag in the rdf catalog consistent?

let's say i have a html and zipped file, of #etext15560 , in this case the download link is
&f;dirs/1/5/5/6/15560/15560-h.zip

The way to recreate from the arguments is obvious (if lengthy), but i seem to recall it changed before - is there a algorithm that always gives a "valid" link, or should i just give up compressing this and include the link in my db?
