I’m just getting started, but so far am using Zotero and exporting (to clipboard) the reference. I have Fleeting, Literature, and Permanent (or, Ideas) folders in my one Obsidian Vault. The Literature vault is a series of notes that include the citation output by Zotero; other content is either a brief summary or linked notes for concepts that warrant it. This is nice as some concepts will overlap across sources, so I like to be able to sort the graph by what ideas arose from a given source or by what sources shared a similar idea. Literature/reference “notes” make this possible.
Ideally, it would be trivial to link a reference from Zotero, or reference a link to that Zotero citation (without having to copy and paste it). I’d also like to be able to filter the graph to include only certain folders, for example, so I could exclude the literature if I don’t want to see that level of complexity.
