“Identifiers” would be more like addresses. A computer metaphor: if you have files, you can think of the path to the file as its identifier. Luhmann used an alphanumeric code (which I think is obsolete on the computer) but you can go with date-time stamps like 202002270807 for 2020-02-27 08:07 or similar. Or you use the title of the note. But then you cannot change the title anymore without breaking links, which makes it brittle.
Linking essentially works exactly as you described: leave the address in other notes in your archive.
This is an area where technology has made the original method obsolete.
In Obsidian (as I use it) one can add #tags, which are automatically indexed, and [[internal_doc_links]] which can be automatically updated on move / rename.
There’s no longer any need to spend time thinking about how to organize this unique id system as though you needed to put a physical card into a linearly ordered physical pile.
Not doing so reduces the friction of taking notes. For me this is very powerful.
