I see. It seems like you may be one of the people that try to coerce relational models into nosql stores like Dynamo.
Or course it's possible. They even trick you into thinking it's a good pattern by naming things "tables".
But if you're using Dynamo to its fullest an ORM is not going to be able to replicate that into a relational store without some fundamental changes.
A "Library of Congress" for published web content maybe. Some sort of standard that allows / requires websites that publish content on oublic-facing sites to also share a permanent copy with an archive, without having the archive have to scrape it.
Sort of like how book publishers send a copy to the LoC.
