The goal, without question, is 100% full coverage on citations for every piece of data that's in the database, even if the citation is an LLM's general reasoning (which for o1-pro is both quite good and often includes study citations).

Right now you'll see that aggregated on some items like this where the reported data is an ensemble of all of the linked resources: https://www.opennutrition.app/search/eggs-eeG7JQCQipwf

Frankly, I just couldn't justify the additional time and monetary expense in doing that if I released this initial version and nobody cared or found it useful. This dataset was also compiled before tools like Claude Citations came out which could make it easier. That is the nature of AI-driven data; I think this is useful now, it is also the worst it will ever be.
