Hi @esuarez! Thanks for your question, and welcome to the community forum!
When a single journal article is published in two languages, each should be assigned its own DOI. In the example below the DOIs are published in the same journal. The original language instance has metadata that contains no indication of the translation instance. The alternative language instance includes in its metadata a relation to the original language instance. Here is a screenshot of the relevant section in the code. Please refer to the code snippet below to see it in context.
Put differently, best practice is twofold:
- In the translation DOI’s metadata, include the element in the metadata for the article
and
- In the translation DOI’s metadata, include an isTranslationOf relationship, pointing back to the original article’s DOI
You can find more information on Relationship types and an example of a translated article here:
A good way to remember our best practice is to note that DOIs are “citation identifiers” not “work identifiers.” That means that if two publications will be cited differently (one in English and one in Portuguese in your example), they should have distinct DOIs. And the same work would be cited differently if it’s in another language, so each language version should get its own DOI.
Please let me know if you have any additional questions.
My best,
Isaac
