The Digital Object Identifier System is for identifying content objects in the digital environment.

Comment

The DOI resolution factsheet specifies that https://doi.org/DOI is the preferred format:

Users may resolve DOI names that are structured to use the DOI system Proxy Server (https://doi.org (preferred)). The resolution of the DOI name in this case depends on the use of URL syntax: the example DOI name doi:10.10.123/456 would be resolved from the address: "https://doi.org/10.123/456". Any standard browser encountering a DOI name in this form will be able to resolve it. The proxy service (both doi.org and the earlier but no longer preferred dx.doi.org) is accessible over IPv6, and supports DNSSEC. The proxy servers respond to HTTPS (preferred) as well as HTTP requests.

Pattern for Local Unique Identifiers

Local identifiers in Digital Object Identifier should match this regular expression:
^10.\d{2,9}/.*$

Example Local Unique Identifiers
10.1038/s41597-022-01807-3   Resolve
10.21/FQSQT4T3   Resolve
10.1333/s00897980202a   Resolve
10.1139/z02-135   Resolve
10.1016/j.foodchem.2008.11.065   Resolve
10.1093/acprof:oso/9780195159561.001.1   Resolve
Pattern for CURIES

Compact URIs (CURIEs) constructed from Digital Object Identifier should match this regular expression:
^doi:10.\d{2,9}/.*$

Example CURIEs
doi:10.1038/s41597-022-01807-3
doi:10.21/FQSQT4T3
doi:10.1333/s00897980202a
doi:10.1139/z02-135
doi:10.1016/j.foodchem.2008.11.065
doi:10.1093/acprof:oso/9780195159561.001.1

Providers

Providers are various services that resolve CURIEs to URLs. The example CURIE doi:10.1038/s41597-022-01807-3 is used to demonstrate the provides available for doi. Generation of OLS and BioPortal URLs requires additional programmatic logic beyond string formatting.
