[Zope-CMF] Relating different objects to each other

[Ausum Studio]

Regarding your workaround, it could work provided your objects ids within
your site are unique, because it's exactly like performing a search by
subjects. If there are more subject keywords of the same name the catalog
will show unwanted results. You can relate objects just using skins.

Some of  us would like the relations being automatically generated by means
of special metadata and a dedicated portal tool. This issue is being
discussed, not singularly but as part of a whole, the metadata
implementations within the CMF. Look for previous messages for the big
picture.
