I suggest the slightly more efficient variation:
(defun jk-org-kwds ()
(org-element-map (org-element-parse-buffer 'element) 'keyword
(lambda (keyword) (cons (org-element-property :key keyword)
(org-element-property :value keyword)))))
The optional argument `element' prevents `org-element-parse-buffer' from
diving too deep and `org-element-map' does the job of `mapcar'.
