symlink means soft link
Discussion
hard links are actually not a real concept in the FS
it is basically 2 different file entries pointing to the same data, say the same file event
it's a kinda artificial distinction but the filesystem behaves differently in that it treats soft links like some kind of file in itself, where the hard links ARE the file itself, but deleting it doesn't affect the other reference, writing it does.
if an event has a d tag on it, and you make two events that point at it with an a tag, then that's really just like a hard link... IF the "file" is a replaceable event, so the reference to it is not to the event ID but to the kind/pubkey/identifier
the analogy breaks down at this point
Yeah, it means symbolic link, but it always refers to soft links. But I lumped the hard link into the same event, as we have the ability to list either e (hard) or a (soft) tags.
Maybe I need a different name, but symlink sounds cool, and this whole topic is incredibly dull and nerdy, and I want to be cool.
yeah, the distinction is that events are immutable, that's the hardest part of it. d tags give you a handle to point a tags at so then you have a kind of mutability. the relay is supposed to recognise this and return the newest (or even delete old versions) when it gets an event with a d tag on it.
