Credits

Viva formats your citations with other people's work. This page says whose, and under what terms. If you are checking whether a reference list Viva produced can be trusted, the short answer is that it comes from the same processor and the same published style definitions that Zotero uses.

The citation processor

citeproc-js

The reference implementation of the Citation Style Language, and the processor Zotero formats with. Viva uses it unmodified, at version 2.4.63.

The citation styles

Each style Viva offers is a definition published by the Citation Style Language project, used unmodified and licensed CC BY-SA 3.0. The people below wrote them.

Where your references come from

Not from a model. Every reference in Viva is returned by Crossref, OpenAlex or Semantic Scholar with a DOI or another stable identifier, and Viva will not show you one that did not come back from one of them. That is the reason it can take a moment and the reason you can check every entry.

The full third-party notices, including what each licence obliges Viva to do, are kept with the code in packages/csl/vendor/ATTRIBUTION.md.
