I like this, but I have suggestions. I think we need to differentiate the model name of known diodes from whatever we as community decided to name others. Example: "BDR-209" is not the 
model of the actual diode, but it is what we 
sourced it from.
Power output and drive current should also be separated between the 
real spec, and what us enthusiasts like to 
over-drive them to.
Other useful info can be pinout, case polarity, and typical threshold current.
To share ideas, here is an example of how I keep track of my own diodes, both known and unknown:
