An illustration of the ZK method on YouTube
This [YouTube video] illustrates one way of implementing a digital Zettelkasten with Obsidian. My comments follow.
Note identifiers are avoided altogether in favor of descriptive filenames. This obviates the timestamp versus Folgezettel question. A tradeoff is that note filenames should be unique and should be considered immutable: a title cannot be changed without changing each reference to the note with that title. This seems like a minor inconvenience, in view of the use of backlinks to create indexes and hubs, below. UPDATE: see the thirteen point comment on the video by JET MECH, especially point 9) cautioning against naming notes or prematurely linking them.
Bibliographic entries (literature notes) are separate notes that link to a note titled Bibliography. The choice of writing bibliographic entries within Obsidian (the slip box component of the Zettelkasten) seems less efficient than working with a reference manager such as Zotero. How well Obsidian supports reference managers might have motivated this choice. However, switching from Obsidian (The Archive, Zettlr) to a reference manager is an interruption. A compromise (in Zettlr or Obsidian) would be to add within the note a citation (e.g., an ISBN or DOI reference), which could be added to the reference manager later. The note could then be updated with a pandoc reference.
Within the note titled "Bibliography," the bibliography is viewable in Obsidian (this will work in Zettlr also) as the list of notes that link to the note Bibliography. That's a clever design, and it's a way to implement structure notes and hubs without writing much more that the title in the structure note. An index of top-level categories could be implemented as a collection of links to notes containing the top-level category names. Visiting the top-level category note and listing the notes that link to it will display that part of the index. Obviously this could be extended indefinitely. For mathematicians and computer scientists: that's a coalgebra for you, otherwise known as a (vertex) coloring.
Zettlr supports backlinks by displaying the list of files that link to the current file. However, as in Obsidian, this feature is most useful if the filename is the note title. One way to find out is to experiment.
I might as well reorganize my ZK along these lines.
