PS: If you are curious (it is quite a profession & specialisation - with, like the IETF, an associated body of international experts collaborating and meeting in far flung places): http://www.digitalpreservation.gov is a good starting point for the US - specifically the normative resources on preservation standards. http://www.worldcat.org/title/long-term-preservation-of-digital-documents/oclc/262692324 is a fairly well known/neutral baseline.
