This sounds like symbolic links vs hard links in file systems. If you change the name of the file that a symbolic link (or shortcut in Windows) points to, it breaks. If you change the name of a file that a hard link points to it doesn't break . The reason for this is that the hardlink doesn't point to the copy of the changable name of the file, it points to a common inode that the other file (with the name changed) points to also. So they are pointing to a common source.
This leads to a similar solution as in file systems. Maybe tiddlers need an abstraction later where the immutable tiddler is like an inode and all renameable tiddlers are just all-field-trancluded inode-tiddlers. You could assign a randomized name to the immutable tiddler but if you want to go further, the names of the inode tiddlers can be a content hash ... maybe a SHA-1 of the tiddler contents ... so if the tiddler content changes, you can relink the hardlink-tiddlers to the new contenthash-tiddler. Then if you want to set up a permalink, it will use the contenthash-tiddler name. Then you can be guaranteed that the *permalink* is actually to the *content* that was originally linked ... if it still exists ... and not just to a ephemeral name. But this is actually sounding a little bit like git. It does offer some pretty lightweight revision tracking possibilities though. I don't think setting up a "redirect" is too tough though depending on the scope ... it is essentially just opening up the tiddler you want to rename, ctrl-A, ctrl-E, put in a new name and pick transclusion or macro ... although the other non-text fields wouldn't get excised+transcluded. Maybe there is a need for a "_content" field that acts like a _canonical_URI field but local to the tiddlywiki and replaces all the fields in the hardlink-tiddler with that of the tidder in the "_content" field. Maybe this is crazy-talk. /Mike On Wednesday, May 5, 2021 at 6:51:28 AM UTC-3 TiddlyTweeter wrote: > Ciao walt, > > Right.
