I have registered two datasources at the OpenData portál ČSÚ (beta).
Both of them have 0 attributes displayed at the details page. (The underlying data have some attributes of course).
You can see attribute table of the data at the table page, however filter by attribute is not working (I guess because the attributes are somehow missing).
Anybody have some issues with registering data in ArcGIS Open Data portal?
After 24 hours the datasources are already in sync with the data.
