Normally, the line (ring)  denotes the Kathode, both in the schematic and on 
the real thing.
If it's a colour coded diode, the thick ring is the Kathode.

But! Back then when I was a student I bought a bunch of diodes that were
mislabeled (i.e. the ring being the Anode) - You can guess I got them for
But since then, I mistrust any labelling. I always test the polarity before
I solder a diode in.


PS.: This was the first mail I got from bode for long. There are quite
fruitful discussions on DIY, on the other hand.
Is there a reason not to merge the lists?
