• Key information about a journal article is now made freely available via its metadata record, a structured and semantically rich format that allows AI/ML processing. • The relationships the article has with other articles is now also present in the form of structured citations in the Crossref metadata record. • Such structured citations should include persistent identifiers such as DOIs with an indication of the type of the citation, such as to a dataset. • The inclusion of persistent identifiers in turn allows AI/ML access to records describing data referred to in the article.
