Microfiche is stable for 500 years, you can store the webpage as-rendered and the source code. And you can use a 2D matrix “barcode” with simple error correction to represent digital data more compactly in the microfiche. Colors are generally less stable in microfiche than black and white. Also, try 1000 year institutions like the Vatican or something. Get it archived on Archive.org If you’re worried about translation, then provide another translation of it in technical and Old Mandarin, ancient Arabic, high Latin, koine Greek, Sanskrit, Hausa (Nigerian), and Shakespearean/King James English. There’s going to be Catholics, Orthodox, random Protestant Christians, Muslims, Confucians, and Hindus in 500 years (plus a lot of Nigerians), and there will be millions of people able to read and understand some of those ancient languages and committed to preserving them.
