FOLLOW and EXPORT are two functions.

FOLLOW should take the link path as the single argument and do whatever

EXPORT should format the link path for export to one of the export formats.
It should be a function accepting three arguments:

  path    the path of the link, the text after the prefix (like \"http:\")
  desc    the description of the link, if any
  format  the export format, a symbol like `html' or `latex' or `ascii'.

The function may use the FORMAT information to return different values
depending on the format.  The return value will be put literally into
the exported file.  If the return value is nil, this means Org should
do what it normally does with links which do not have EXPORT defined.

Org mode has a built-in default for exporting links.  If you are happy with
this default, there is no need to define an export function for the link
type.  For a simple example of an export function, see `org-bbdb.el'.

If TYPE already exists, update it with the arguments.
See `org-link-parameters' for documentation on the other parameters."
