Is just repackaging and selling open data viable? Or should businesses be more sophisticated, aggregating and adding valuable insights to the data?
Some data sets are switching from OGL to restricted licences – like the ratings list. That has stopped some uncomfortable commercial uses – but killed some academic uses as well. The OS polygon data has been problematic because the co-ordinates can’t be republished. That’s been tightened up in a way that makes them completely useful commercially, because of wording that encapsulates all “benefitting” from the data.
