How to preserve a time capsule?

I want to make a time capsule for future generations, possibly in thousands of years, or as long as possible. I know GLASS would never break down if kept safe (cased in concrete or something). How would I use the materials though? I mean...how long would the paper last inside the glass bottle? How long would the paper last if I laminated it and then put it in a glass bottle?

Basically I need the best ways to secure information for as long as possible. Is air a cause of corrosion? Would I need to make my glass bottle air tight?

So far I thought about placing all the information on paper, laminating, putting it in glass bottles, then placing those inside a metal case, maybe an old safe, and then sealing the safe in a good foot thick surrounding of concrete or something like that.

Any tips would be appreciated.

Thanks.
