[Zope-CMF] Portal Topics as items' metadata

[Ausum]

How would you attach Portal Topics to standard items' metadata? 
I've been looking for a solution to the problem of automating a "related
content" box to every portal object, and Portal Topics seem to be the
answer.

By allowing every portal object (text, image, or multimedia content) to
trigger a keyword-based search to the whole portal archive, it looks
pretty possible to count on this type of box, not simply as a textarea
(as it was my first approach), but as a living thing. Just like high end
content management systems.

Would you please point me in the right direction to this purpose?

Thanks in advance,
