* Zotero, with BetterBibTex plugin [^2]
* pandoc, through its updated citeproc library [^3]
* the citation plugin for Obsidian, which uses CSL-JSON [^4]
This might in the end be my personal preference, but a standardized JSON format (which is just as easily adaptable to YAML [^5]) seems much easier to parse and modify than Bibtex, with its sheer complexity. If we want to have the ability to easily cite anything, then this direction of standardization, I believe, is a must.
