Andrew summarises with clarity the current state of licensing for “open” geodata on his blog. This is going to be an emerging theme over the next year as more data becomes available and there is greater awareness of the immature state of data licensing compared to software licensing.
When I touched upon the subject over the summer is was within the context of DRM a scary umbrella term that has too much baggage, but one which at least in an abstract sense describes the problem.
I have no doubt that the open geodata community will go through the difficult and potentially painful process the software industry experienced to reach the current broad range of potential licenses. This is a necessary step for as Andrew points out for many potential data publishers there is no standard license that is close enough to matching their needs.
As this process takes place a good resource is Kevin Promfret’s excellent blog on spatial law who is tracking licensing developments.
