I use Dwc-A to feed my BD.

We know the limits of the Dwc star schema to represent a relationnal

For example in the case of 1-n cardinality :  specimen --- event/record ---
If i understand the concept, I need to use the Darwin *Core* *Occurrence*
*extension*, denormalize my relational model in a big raw model and
transform / re-normalize this model to match with my DB model.

In order to reduce cost*, *dev and optimize sql statement, it will be
grandly appreciate to add custom extension. In this case, i can to be very
close of my relational database model and avoid multiple step of dev.

I discovered this link but explanantion is now deprecated
