Healthline fields in every export
Article records carry the title, topic and condition, category, author, medical reviewer as credited, publication date, last medical review date, last updated date, word count, section structure and the address.
Three dates are kept apart: published, updated and medically reviewed. They mean different things, they diverge, and a corpus that keeps one of them and calls it the date cannot answer the only quality question worth asking of health content.
Reviewer credentials are recorded as published, since a review by a physician and a review by a dietitian are different claims about the same article.
Section structure is preserved rather than flattened, because health articles follow a recognisable shape - symptoms, causes, treatment, when to see a doctor - and comparing coverage depth across publishers is a section-level question.
Every row carries the collection timestamp and a revision count where re-collection shows the article changed.
