I don't know how to "abstract" ...

:-)

Now, perhaps someone will ask, "won't doing all the data be overhead?"

I don't think so.  Now the system service must decode the item list, make 
decisions, and such.  To load a data structure, it's most likely sequential 
code, one pass, and done.

But what do I know?

Not how to "abstract" ???
