Forum OpenACS Q&A: Response to What is the best way to implement many-to-many relationships between ACS Objects?

Simon,

Excellent point.

I found this quote from the design docs

"The advantage of registering this table as a relation type is that in principle the OpenACS 4 object system could use the meta data in the types table to do useful things in a generic way on all relation types. But this mechanism doesn't really exist yet."

So is there anything a centralized table and relation_types can do that a mapping table for each relationship type cannot do?
