Primo uses Citation Style Language to generate citations for bib records. Presumably the bibliographic metadata is at some point converted to a csl-data object. https://github.com/citation-style-language/schema/blob/master/schemas/input/csl-data.json

It would be helpful if that csl-data JSON object was available through the Primo Search API. This could be a additional information one could request from the API. https://developers.exlibrisgroup.com/primo/apis/docs/primoSearch/R0VUIC9wcmltby92MS9zZWFyY2g=/
