Rename multiple files based on their front matter

As already noted, Denote can rename a file based on the data in its front matter (Rename a single file based on its front matter). The command denote-dired-rename-marked-files-using-front-matter extends this principle to a batch operation which applies to all marked files in Dired.

Marked files must count as notes for the purposes of Denote, which means that they at least have an identifier in their file name and use a supported file type, per denote-file-type. Files that do not meet this criterion are ignored, because Denote cannot know if they have front matter and what that may be. For such files, it is still possible to rename them interactively (Rename multiple files interactively).
