I have something like this implemented for the server images plugin. It hooks into the import mechanism and makes changes to the tiddler. For that it saves the image on a server but having it change the tiddler title or make other modifications to fields should be relatively straight forward. The relevant bits of code are here: https://github.com/OokTech/TW5-ServerImages/blob/master/ServerImages.js
You would have to have some way to determine how to define the prefix because the import doesn't get much information about the source of the tiddlers. -- You received this message because you are subscribed to the Google Groups "TiddlyWiki" group.
