As mentioned it very much depends on the system.
 
In general I prefer systems which can support the "one to many" approach where a symbol can map to multiple footprints. These systems are typically supported by a database.
 
For symbols which incorporate the pin number mapping I use this convention:
 
[Prefix]_[item]_[Variant]
 
For an IC the prefix would be IC and the item would be the manufacturers part number with RoHS and packaging codes removed.
 
For other parts such as Transistors the prefix would be Transistor the item could be NPN and the variant would be the pin mapping in the order of pin e.g.
 
Transistor_NPN_ebc
 
This is an NPN transistor with emitter pin 1, base pin 2 and collector pin 3
