I've noticed in many books, papers, and model examples that many name their roles in a lowercase fashion and as an abbreviation of the original classifiers. Where did this convention come from and are there other naming conventions?
See page 234, Figure D.19 - Internal Structure of the Power Subsystem (Internal Block Diagram
There is "fp" for FuelPump or "trsm" for Transmission.
Finally, when documenting our models, in any tool you can provide a description for parts as well as classifiers. I was wondering what the difference is when documenting part and classifiers. I end up usually copying and pasting the description of the classifier into the part as well, but perhaps that is not accurate. For example, in the description for FuelPump you write "The Fuel Pump block is etc. etc." In the IBD diagram, for the part "fp", the descrption would also be "The Fuel Pump block is etc. etc." Something doesn't seem right there, but I have no criteria for differentiating.
