[Erp5-dev]global classification

[shan sverige]

Hello, 

I'm implementing a global classification in my own projects in a 
similar way you describe in 
http://www.erp5.org/wiki/whitepaper/ImplementingMetaLevel

Now, because each Category (you call it leaf of a classification tree) has
a many-2-many relationship with a content object (one content object 
can belong to more Categories and one Category classifies multiple content    
objects), I plan to use the mxmRelation product. 
Because mxmRelation comes with a nice interface (5 methods) and all
other approaches too implement many-2-many seems clumsy. Downside
of MxmRelation is it's lack of scalability

Are you also using that product or do you implement many-2-many differently?

regards
Aku
