I'm trying to keep a database of minerals and their attributes, etc. In order to do this properly I would like to know the following:

1- Will resource "XYZ" always have the same attributes. Even from different concentrations / locations / planets / servers / dates ?

2- Will resource "XYZ" always be available somewhere or do they get "phased out" and not used again? ( I know that some type of a resource TYPE will always be avaialble somewhere in the galaxy, but what about a specific resource of that type)

3- Do new resource names get created, or are the items currently available going to be the same forever.

Thanks,
