I am looking for an org-mode based static site generator which supports categories and subcategories like mediawiki. The existing static site generators support only tags.
For eg: consider an org file earth.org that talks about earth and filed under 'Planets' Category. There is an existing category hierarchy like universe > solary system > planets.
earth.org #+Category: Planets # Should export earth.org with following navigation bread crumbs. Category: universe > solar system > planets
Similarly categories like moon, asteroids can be sub category of solar system. Clicking on solar system should display links to moon and planet sub categories.
Is it possible to achieve such a static site?
