Open metadata

Open and comprehensive metadata is a key requirement of many transformative agreements. The following tables illustrate potential gaps in Crossref metadata for Open Access articles in hybrid journals included in transformative agreements.

License metadata gaps

BMJ Publishing: Comparison of open licence metadata in Crossref with Unpaywall via OpenAlex per year. You can compare global metrics with metrics only for articles by lead authors based in Germany. In addition to Crossref licence information, Unpaywall also analyses publisher websites to determine whether an article has been published under an open content licence. More Open Access articles derived from Crossref may indicate a delay between metadata changes and Unpaywall-indexing, while more Open Access articles identified by Unpaywall suggest that publishers have not deposited licensing metadata in Crossref for all articles.
