Author object
cited_by_count: 38
List:
Author.works_count and Author.cited_by_count for each of the last ten years, binned by year. To put it another way: each year, you can see how many works this author published, and how many times they got cited.Any works or citations older than ten years old aren't included. Years with zero works and zero citations have been removed so you will need to add those in if you need them.

String: The date this
Author object was created in the OpenAlex dataset, expressed as an ISO 8601 date string.created_date: "2017-08-08"
String: The name of the author as a single string.
display_name: "Jason Priem"
List: Other ways that we've found this author's name displayed.

"Jason R Priem"

String: The OpenAlex ID for this author.
id: "https://openalex.org/A5023888391"
Object: All the external identifiers that we know about for this author. IDs are expressed as URIs whenever possible. Possible ID types:
twitter(String: this author's Twitter handle)wikipedia(String: this author's Wikipedia page)
Most authors are missing one or more ID types (either because we don't know the ID, or because it was never assigned). Keys for null IDs are not displayed.
ids: {
openalex: "https://openalex.org/A5023888391",
orcid: "https://orcid.org/0000-0001-6187-6610",

},
Object: This author's last known institutional affiliation. In this context "last known" means that we took all the Works where this author has an institutional affiliation, sorted them by publication date, and selected the most recent one.
This is a dehydrated
Institution object, and you can find more documentation on the Institution page.last_known_institution: {
id: "https://openalex.org/I4200000001",
ror: "https://ror.org/02nr0ka47",
display_name: "OurResearch",

type: "nonprofit",
lineage: ["https://openalex.org/I4200000001"]
},
String: The ORCID ID for this author. ORCID is a global and unique ID for authors. This is the Canonical external ID for authors.
Compared to other Canonical IDs, ORCID coverage is relatively low in OpenAlex, because ORCID adoption in the wild has been slow compared with DOI, for example. This is particularly an issue when dealing with older works and authors.

Object: Citation metrics for this author
2yr_mean_citednessFloat: The 2-year mean citedness for this source. Also known as impact factor. We use the year prior to the current year for the citations (the numerator) and the two years prior to that for the citation-receiving publications (the denominator).
While the 2-year mean citedness is normally a journal-level metric, it can be calculated for any set of papers, so we include it for authors.

2yr_mean_citedness: 1.5295340589458237,

String: The last time anything in this author object changed, expressed as an ISO 8601 date string. This date is updated for any change at all, including increases in various counts.
updated_date: "2022-01-02T00:00:00"
String: A URL that will get you a list of all this author's works.
We express this as an API URL (instead of just listing the works themselves) because sometimes an author's publication list is too long to reasonably fit into a single author object.
works_api_url: "https://api.openalex.org/works?filter=author.id:A5023888391",
works_count: 38
This is updated a couple times per day. So the count may be slightly different than what's in works when viewed like this.
The "x" in
x_concepts is because it's experimental and subject to removal with very little warning. We plan to replace it with a custom link to the Concepts API endpoint.List: The concepts most frequently applied to works created by this author. Each is represented as a dehydrated
Concept object, with one additional attribute:score(Float): The strength of association between this author and the listed concept, from 0-100.
