That's GPL, if that makes a difference to you, and designed for  
intrinsic relationships.  There's also

- zc.relationship, which is ZPL, relatively simple in concept,  
designed for extrinsic relationships between persistent objects, and  
pretty flexible;

- zope.agxassociation, which is ZPL, relatively simple in concept,  
and designed for intrinsic relationships;

- zemantic, which is extrinsic, RDF-based, and designed for the full  
flexibility of RDF;

- Jean-Marc Orliaguet's relationship code, which is based on  
extrinsic triadic relationships, GPL, and used for CPSSkins;

- Helmut Merz's relationship code (http://svn.cy55.de/viewcvs/Zope3/ 
src/cybertools/trunk/relation);

- and more, I bet!

Whew!
