At the moment there is no easy way to tag topics with the date/time of the last 
change to the topic in Ontopoly. Adding a predefined PSI to the ontology, and 
automatically updating the field for topics which have it would solve this 
easily.

I've been looking for a mechanism to add occurrences to topics when they are 
modified, e.g., added by user xyz at datetime, modified by user..., deleted by 
user...
The last one (deleted by user...) is more complex, of course.

Here is a sample of how you can listen for changes in a topicmap. This specific 
case will add or update last-modified-at occurrences for changed topics.

Ontopia does not recognize users internally, so you have to find another way to 
store last-modified-by.

When it comes to deleted-by-user: this is completely domain specific. It would 
require you to *not* delete the topic, but flag it as deleted. Any query would 
then need to take this flag into account.
