What this article record gives an agent

A summary it can quote

Our short summary, marked as ours, separate from the publisher's own words and byline.

Companies, resolved

Who the article is about and who it names, each linked to a company record, not just a name in text.

The source, kept

The original URL, publisher and date, and what kind of piece it is (press release, news, analysis).
