Unfortunately, there is currently no way to download one's bookmarks - and these are not comprised in the archive - the biggest problem.
Please let me know, if you found a kind of scraper (nodejs solution?) which which one can locally download the bookmark (urls/status ids would be sufficient to feed your script with those, I suppose.
