One example given in docs/file-format.md is as such:

kinetics:
    type: Article
    title: Kinetics and luminescence of the excitations of a nonequilibrium polariton condensate
    author: ["Doan, T. D.", "Tran Thoai, D. B.", "Haug, Hartmut"]
    doi: "10.1103/PhysRevB.102.165126"
    page-range: 165126-165139
    date: 2020-10-14
    parent:
        type: Periodical
        title: Physical Review B
        volume: 102
        issue: 16
        publisher: American Physical Society

Which doesn't seem to work correctly nor correspond with the rest of the documentation, which says doi should be placed within serial-number, in which case Typst seems to recognize it correctly
