Another quick question :)<br>Are the rules for creating a download url from the &quot;file&quot; tag in the rdf catalog consistent?<br><br>let&#39;s say i have a html and zipped file, of #etext15560 , in this case the download link is <br>

&amp;f;dirs/1/5/5/6/15560/15560-h.zip<br><br>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 &quot;valid&quot; link, or should i just give up compressing this and include the link in my db?<br>
