DOI Creator

DOI Creator registers a Digital Object Identifier (DOI) on DataCite for each content you publish, and stores it in the doi custom field of the content, so that your theme can show it. Features

• Automatic registration when a content is published, scheduled contents included. It can be turned off, to register DOIs only on request.
• Any content type: posts, pages and custom post types.
• Your DOI format: prefix plus a suffix pattern with placeholders ({year}, {month}, {issue}, {volume}, {counter}, {post_id}, {random}), with a live preview.
• Rich metadata: resource type (journal article, preprint, report...), authors from Co-Authors Plus (guest authors included) with ORCID iD and affiliation (with ROR ID), journal title, ISSN, volume and issue, publication date, abstract from the excerpt, language (Polylang supported), subjects from tags or categories, Creative Commons license.
• Preview: see the exact request DataCite would receive for any content, before registering anything.
• Test mode with the DataCite test environment, and a connection test that checks credentials and prefix.
• Content list: DOI column, filter by DOI status (with DOI, without DOI, failed) and a "Register DOI" bulk action, also for contents published before.
• DOI box in the editor: see the DOI, register it now or update its metadata on DataCite.
• Reliable: temporary errors (network, DataCite unavailable) are retried automatically; every registration, update and error is listed in the activity log.

The DOI Each DOI is made of the DOI prefix set in the settings (optionally followed by a fixed part of the suffix) and of a suffix built from a pattern. The default pattern, {year}-{issue}-{counter}, gives DOIs such as 10.5438/0012/2021-1-2: the year, the issue number (from the periodicity of the journal) and a progressive number. The metadata With the "Enhanced" metadata profile DataCite receives: title, authors (with ORCID iD and affiliation when set in their profile), publisher, publication year and date, resource type, a description with journal, issue and year, and, when enabled, abstract, language, subjects, license and journal (title, ISSN, volume, issue). The "Classic" profile sends exactly the metadata of version 1.0: generic "Text" type ({ "ris": "RPRT", "bibtex": "article", "citeproc": "article-journal", "schemaOrg": "ScholarlyArticle", "resourceTypeGeneral": "Text" }) and a description with journal, issue and year (e.g. "CoolJournal, 3 (2021)"). Sites configured with a version before 1.1 keep this profile until they change it. Every DOI is registered with DataCite's technical "source" field set to doi-creator-wp. It is not part of the DOI metadata (it does not appear in citations or in the metadata XML), but it is public: it lets the author of this plugin count, from DataCite's public API, how many DOIs are registered with it. Coming soon Crossref, for journals and publishers that are Crossref members.

1.1.0

• New settings page, organized in sections: overview with statistics and setup checklist, connection, DOI format, content, metadata, activity.
• DOI suffix pattern with placeholders and live preview.
• DOIs for pages and custom post types.
• Enhanced metadata profile: resource type, publication date, typed descriptions. Optional abstract, language, subjects, license and journal (title, ISSN, volume, issue).
• ORCID iD, affiliation and ROR ID of the authors, for users and Co-Authors Plus guest authors. Guest authors are now read correctly.
• Content list: DOI column, filter by DOI status and "Register DOI" bulk action.
• DOI box in the editor: register now, update metadata on DataCite.
• Optional metadata update on DataCite when a content with a DOI is updated.
• Connection test, metadata preview and activity log.
• Temporary errors are retried automatically.
• The date used for year and issue can be the publication date of the content.
• Sites configured with a previous version keep exactly the same behaviour until they change the new settings.

1.0.4

• DOIs are registered with DataCite's technical "source" field set to doi-creator-wp, so that the number of DOIs registered with this plugin can be counted from DataCite's public API. No DOI metadata is changed and no data is sent anywhere else.

1.0.3

• Fix: DataCite rejected every new DOI (HTTP 422, "titles: Value at root is not an array"). Titles are now sent as a list, as required by the DataCite REST API.
• Fix: authors were read from global variables instead of the post being published, so DOIs could be skipped when posts were published by WP-Cron or other background processes.
• Fix: DOIs for posts published from the block editor are created after Co-Authors Plus has saved the authors.
• DataCite errors are now written to the PHP error log instead of being silently ignored.
