[O] the "right way" to build OMPL export and import

[Alexis Gallagher]

Hi,

I would love to be able to export org documents to opal, so that I can read 
them with the various commercial outlining apps on platforms without emacs -- 
e.g, iOS. The ideal thing would be if I could import OPML as well.

Is anyone working on this already?

If not, does anyone have any pointers on the "right way" to go about this, so 
that the work would go smoothly and be acceptable upstream? This seems like a 
good time to ask given the recent consolidation of export facilities around the 
internal parser org-element.el.

I presume any OPML exporter should be based on that, correct? Is any one of the 
existing exporters a particularly clean example to work from?

For OPML import, is org-element-interpret-data the best starting point?
