Hey, this is the update at 12/19/2016.
I have updated the application so that now it supports Socrata and DKAN portals. So far it is actively tracking 287 data portals (see the list), which are located at all continents on earth and publishing ~1 million datasets. Though there are still a few European portals (~20) to add, this application is very close to achieve its primary goal, which is to provide a living map of the world of open data.
I am considering the roadmap of development in 2017. If you have any idea/suggestion about new feature and platform to support, please feel free to discuss with me.
Finally, happy holiday to all of you
