Data format

{% hint style="danger" %} This data schema is in beta and can change with little notice. {% endhint %}

OA.Report collects data on scholarly works such as papers, preprints, datasets, and code. Some of that data is generated by OA.Works and some are reused from other open sources.

For an example of a record with most of the possible fields, go to https://api.oa.works/report/works/10.1016/j.ijid.2020.05.122

See Crossref's documentation for the following keys:

  • funder
    • name
    • award
    • DOI
  • subject

{% hint style="info" %} Note: Crossref is not our only source of funding data. However, it is the best source of open, structured data. {% endhint %}

See OpenAlex's documentation for the following keys:

  • doi
  • title
  • subtitle
  • journal
  • publisher
  • issn
  • volume
  • issue

  • oadoi_is_oa (see `is_oa`)
