Hello, I'm currently doing some research about the best way(s) to publish open data for a local administration. For many of the data they wish/can publish the license question is quite straightforward, but there's one database which raises much questions. I try to expose the problem as simply as possible:
1-the database : shape files with routes and POI about a region. 2-the context : the administration makes some money selling a walking guide using those informations 3-the aim : opening those data so that eventual reuses will publish correct information about pathes, dangers, etc. 4-the dilemma : open publishing those information may serve any competitor editor to build a competiting guide upon those data 5-the question : how licensing could help preventing such an usage while welcoming more friendly reuses such as : a promotional guide for hiking in the area that would reuse some of the data for the sake of promotion.
*4b : let's assume that the dilemma is real. I mean : the risk may not ba as big as their fears, but this is not my point here.
Licences evaluated, and the point where I am :
- Open Licence (https://wiki.data.gouv.fr/images/0/05/Open_Licence.pdf),
or CC-BY : welcomes *every* reuse, so won't solve the dilemma.
- CC-BY-NC : may sound appropriate, but : non free (I'd dislike very
much ending up in recommending a non-free license), would prevent some legitime reuses (let's imagine that the promotional guide has anything to do with a commercial use)
- CC-BY-SA : this is the way I'd choose for :
- it's free
- the constraint introduced is only reclaiming openness
- it may solve the dilemma, but can you help me answer following
questions ?
Let's assume the competitor wants to use the shape files under CC-BY-SA along with a closed base map bought from a vendor to have a nice looking printed guide. => publishing such a reuse of the data seems to lead to a licences conflict : the closed license would say something like "all rights reserved, reproduction forbidden", where the CC-BY-SA part would claim "any reuse of this data will be under this same license" => How to solve that ? If it' not solvable, this means that the commercial reuse cases of the data opened under CC-BY-SA are quite a complicated way, which I find a reasonable manner to solve the original dilemma
Am I on the right way with my assumptions and questions ?
