I'm not sure the source tag is enouh to identify a derived work. If person A adds a way by tracing (for example) Nearmap data which gets rendered as a map, and person B adds a nearby street based on what they saw on the map plus what they know of the area (source=local_knowledge), all are derived from the original edit. (esp in the context of cc-by-sa)
Removing everything with source=nearmap doesn't solve this. - Ben Kelley Sent from my HTC -----Original Message----- From: David Murn <[email protected]> Sent: Monday, 2 May 2011 10:17 To: Andrew Gregory <[email protected]> Cc: OSM Australian Talk List <[email protected]> Subject: Re: [talk-au] How many NearMap users do you think have accepted the new CTs and ODbL?

That is what one would hope, but no-one has been able to give a straight answer. The problem with this, is how many source= tags do they have to check for and remove? The problem isnt specific to nearmap, it is a general problem for all data derived from sources using differing licences (for example, ABS, yahoo or data.gov.au, just in Australia). It is easier to simply remove every edit from a user than for them to automate the process of figuring out what was sourced from where. _______________________________________________ Talk-au mailing list [email protected] http://lists.openstreetmap.org/listinfo/talk-au
