Yesterday the Rogue Scholar science blog archive started using Crossref schema 5.5 that was released last Friday.

The most relevant change in the new schema for Rogue Scholar is the introduction of a dedicated content type blog post (as type posted_content, subtype blog). This makes it easier to cite blog posts with Crossref DOIs as many citation styles (e.g. APA) format blog posts differently than preprints. And it also makes it easier to recognize the content type of a reference, as previously Rogue Scholar used the generic preprint/posted_content content type.

The other important change in schema 5.5 is the support for CRediT contributor roles. Rogue Scholar already supports a wider range of contributor roles, and this is now reflected in the metadata sent to Crossref.

Rogue Scholar will over time update all more than 50K blog posts to use schema 5.5. Crossref schema 5.5 support is via the commonmeta-py library, which will also provide Crossref DOI registration functionality to other repositories using the InvenioRDM platform in the upcoming v14.0 release.

Please reach out via Slack, email, Mastodon, or Bluesky if you have any questions or comments.

Rogue Scholar is a scholarly infrastructure that is free for all authors and readers. You can support Rogue Scholar with a one-time or recurring donation or by becoming a sponsor.
