Small demo.... had some spare time ;-)
Request:

Sitemap snippets:
-----------------------------------------
<map:match pattern="testfilemeta/**">
<map:generate src="{1}" type="filemeta">
<map:parameter value="dd/MM/yyyy" name="dateformat"/>
</map:generate>
<map:serialize type="xml"/>

<map:components>
<map:generators>
<map:generator label="image" name="filemeta"
src="com.ciber.cocoonDemo.FileMetaGenerator" />
</map:generators>
....
</map:components>
Output:

Hi Mathias,
You might create your own FileMetaGenerator which extends
org.apache.cocoon.generation.AbstractGenerator
You could let this FileMetaGenerator generate an xml snippet like:
<file:file xmlns:dir="http://apache.org/cocoon/file/2.0";>
<file:lastmodified>1056668768203</file:lastmodified>
<file:name>input.xml</file:name>
<file:path>...</file:path>
<file:isDirectory>false</file:isDirectory>
<file:isFile>true</file:isFile>
....
</file:file>
Then you could use the aggregator to aggregate your xml file with this
fileMeta.xml and run a stylesheet over the aggregated xml to extract
the info you need.
There are probably better ways to do this but this is the first thing
that comes to my mind.
Robby

Sorry. We use xml files (and database entries in the future) that are
converted by cocoon to html. The generated page must show when it as
last changed. So for the start I would want to use the MTIME of the xml
input file to show it on the html page.
The long shot goal:
When we add the database as additional input source, I would like the
take db updates/modifications also into account. I'm not even sure if
this is possible at all.
thanks
Mathias
