Examples
Worked examples
- Is an instance
https://doi.org/10.1038/nature14539 resolving with a 302 to nature.com.
- Is an instance
Content negotiation on the same DOI returning Crossref JSON metadata when Accept: application/vnd.citationstyles.csl+json is sent.
Counter-examples
Looks similar, but isn't
- Not an instance
A 404 result when calling https://doi.org/10.xxxx/dead is a failure of resolution, not the resolution mechanism itself.
- Not an instance
Searching for a paper in a search engine is not PID resolution.
Editorial commentary
Resolution typically uses HTTP: a client makes an HTTPS request to the resolver (e.g. https://doi.org/10.xxxx/yyyy), and the resolver responds with a 302 redirect to the current landing page or, under content negotiation (Accept: application/json), with structured metadata. The Handle System uses HTTP for proxy resolution but also supports a native HDL protocol for high-throughput cases. ARKs add the inflection convention as a metadata-resolution mechanism. The resolution layer is the operational manifestation of a PID’s persistence — broken resolution is a broken PID.
