SnapEDA needs rules/guidelines for symbol/footprint creation

This site seems like a great idea, but without some conventions to guide it, it will be chaos, and the data created will be practically unusable. For example, for Altium:
Footprints should be named by the IPC guidelines. Schematic symbols should be named according to some defined convention, and should contain the following user parameters at a minimum:
MFG PN, Alt MFG1, Alt MFG1 PN, DIST, DIST PN, DNP, MFG, REACH, ROHS, TESTED
Schematic pins should be placed on a grid of 10.

Footprints should be created according to IPC guildelines, with the following additional mechanical layers:
Mechanical 13 (M13) Top layer component body information (3D models and mechanical outlines, paired with M14).
Mechanical 14 (M14) Bottom layer component body information (3D models and mechanical outlines, paired with M13).
Mechanical 15 (M15) Top layer courtyard and assembly information (paired with M16). This normally includes a cross-hairs at the origin of the component.
Mechanical 16 (M16) Bottom layer courtyard and assembly information (paired with M15). This normally includes a cross-hairs at the origin of the component.
