Hello Crossref,
I am wondering if the data shown in your openurl end point is showing data that was submitted or is data that is in your system?
I am using https://api.crossref.org/works/DOI as the Crossref source of truth. Wondering how or if I should also be using the open url data.
I am looking at ways to validate Crossref data with our internal data.
Hello, and thanks for your question.
All our metadata retrieval methods derive their data from the same starting point: the xml metadata deposits that are submitted by our members when they register their content.
Typically, openURL is used as a method to link to the DOI resolution landing page when you’re starting with a reference (or the metadata comprised by a formatted citation), but not necessarily with the DOI. It can be used to retrieve metadata, rather than to resolve directly to the item’s landing page, but that’s a less common use case.
If you’re happy with the process of using the REST API, there’s no particular reason you would need to switch to openURL or one of the other query options.
Please let me know if you have any further questions.
