Doi
On this page
A digital object identifier, naming a paper or a dataset: 10.1038/nphys1170.
Use it to cite publications. For a person, use Orcid.
Shape
One value, held as text in one set form, with no parts: 10.1000.10/123456.
Example
Doi("10.1038/nphys1170")Doi(raw) checks the text, and text that isn't one breaks the format rule.
text.parse(raw, as: Doi) reads one from text that comes from outside. Text that isn't one at all fails malformed, such as doi:10.1000/182, https://doi.org/10.1000/182 or 10.1038/NPHYS1170.
Good to know
- It has no resolver in front, so
doi:andhttps://doi.org/are refused. ==tells you whether two are the same.<andlist.sort_bydon't take it.
In JSON
A string, in a request, a response or json.write:
"10.1000/182""10.1038/nphys1170""10.1002/(sici)1097-4571(199806)49:8<693::aid-asi4>3.0.co;2-o"
Details
Text form, storage, how it is shown, and operations
Doi is in the group Software, and has been in Jadpo since 0.1.0.
Text form
text.from writes one standard text form, the same form text.parse reads back: 10.1000/182, 10.1038/nphys1170 and 10.1002/(sici)1097-4571(199806)49:8<693::aid-asi4>3.0.co;2-o.
How it is stored
It is stored in one column named for the field, of type text. 10.1002/(sici)1097-4571(199806)49:8<693::aid-asi4>3.0.co;2-o is stored as '10.1002/(sici)1097-4571(199806)49:8<693::aid-asi4>3.0.co;2-o'.
How it is shown to people
text.format(value, locale:) shows it to people in their locale.
With locale: Locale.en_gb:
