Hi
The current org latex export will export a link doi:10.xyz/abcd without
the protocol prefix as 10.xyz/abcd. Correctly, it should retain the
prefix.
An easy fix is adding "doi" to the list of protocols that retain
the link type string in ox-latex.el, below.
################### ox-latex.el ###############
(defun org-latex-link (link desc info)
"Transcode a LINK object from Org to LaTeX.
DESC is the description part of the link, or the empty string.
INFO is a plist holding contextual information. See
`org-export-data'."
(let* ((type (org-element-property :type link))
(raw-path (replace-regexp-in-string
"%" "\\%" (org-element-property :path link) nil t))
;; Ensure DESC really exists, or set it to nil.
(desc (and (not (string= desc "")) desc))
(imagep (org-export-inline-image-p
link org-latex-inline-image-rules))
(path (cond
;; ----- NEXT LINE CONTAINS THE FIX -------
((member type '("http" "https" "ftp" "mailto" "doi"))
(concat type ":" raw-path))
((and (string= type "file") (file-name-absolute-p raw-path))
(concat "file:" raw-path))
(t raw-path)))
protocol)
