I've examined wordpress export file with post kinds plugin installed and known rss feed export.
That known RSS has no syndication links, like-of links and similar.
I don't find it very usefull.
Currently I'm looking into the known database trying to figure out if I can parse the json contents and generate xml wordpress importer is expecting with post kinds taxonomies present.
I'm still trying to import data from my known site into wordpress.
Has anyone done something similar.
Doing it all from the ground seems a lot of work to me, so I'm also looking if I can find something I will be to make it easier for me.
