Is it possible to share information across campaigns?

[Barwickian]

As subject.

Examples:

I'm running a Rise of the Runelords campaign. I can see putting quite a bit of Varisia and Golarion background whcih would be useful for running other Adventure Paths or my homemade freeform campaigns.

Or Traveller's Spinward Marches - I'd be using similar baseline info on the Third Imperium and the Marches for The Traveller Adventure and the Ancients series.

I don't want to have to input all the background, field by field, into multiple realms.

Is it possible to create a master realm to hold the common background of the gameworld, exporting the data into specific applications of that gameworld (ie, individual campaigns)?
