org-dp.el (and org-dp-lib.el) are libraries of mine that aim to make
local programming with org-elements (org-element-at-point) as convenient
as global programming (org-element-parse-buffer), see
https://github.com/tj64/org-dp. I find them very useful, unfortunately
they have been widely ignored so far ;)

This was just an example (using local parsing for convenience), giving
the hint that you could put some links of interest in an Org file, parse
it, and look at the (link (:type ...)) alists in the parse tree to see
the properties you need to get and set. The internal link representation
is the same for all types anyway.
