Hi All,
I have this problem in using ZCatalog.
I have the Zcatalog and the folders that contained the DTML
Documents in the root.
Ok I think I understand what you are trying to do here::

    <dtml-call "REQUEST.set('mm', 
ZopeTime().toZone('GMT+1').strftime('%d%m%y'))">
     <ul>
     <dtml-in "Zcat_Index_1_Dtml_Doc(id=mm)">
         <dtml-var expr="_.getitem(mm,1)[0:400]">... <br>
         <li>
         <a href="&dtml-absolute_url;"> More </a>
         </li>
     </dtml-in>
     </ul>

I think your code could be expressed a little better like::

    <dtml-call "REQUEST.set('now', 
ZopeTime().toZone('GMT+1').strftime('%d%m%y'))">
     <ul>
     <dtml-in "Zcat_Index_1_Dtml_Doc(id=now)">
         <dtml-var "_.getitem(now,1)" size=400>... <br>
         <li>
         <a href="&dtml-absolute_url;"> More </a>
         </li>
     </dtml-in>
     </ul>

If you want to want to be able to show the absolute_url from the 
cataloged object you need to create a "Metadata" called 'absolute_url' 
in the catalog. Then it will be saved together with the rest of the 
objects metadata.

you can probably use the pathindex like this::

    pathindex='path/to/some/*/document'

with a wildcard character.

But I will warn you that it is a pretty dirty way you are using zope. 
There are quite a lot of problems in your approach with document 
components saved as seperate Dtml-Documents.

In the long run I think you will be more satisfied with a solution based 
on html or structured text in a single dtml-method.

Or create a single Python Product or zClass that has some of the 
following attributes::

    class article:

        id
        title
        summary
        content # only 1 field for content
        author
