[Osmf-talk] License Working Group - license change proposal status

Hello all,

I have started to read the various wiki pages regarding the proposed ODBL and most is clear, till far. But I struggle with the following.
How will the proposed licence benefit OpenStreetMap?

I read:
"requires those that combine our data with their own data will have to give the latter to OSM. This means we get more open data. Under the current licence, they have to make the end result copiable (such as a map), but not the source data."

What is the exact definition of "own data"

Imagine a situation where I use OSM data and at my site, add the location of my chicken shed, pig stable and my lawnmower, is this the "own data" that you refer to above?

Imagine a situation where I will use OSM data on my site and will place a marker at the local town hall, is that marker location "own data"?

What if I add a popup with text describing the town hall, is the text inside the popup "own data" ?

This for starters, more to come.

I hope that the publishing of the formal proposal has helped answer some earlier questions.  A reminder that you can read it at http ://www.osmfoundation.org/images/3/3c/License_Proposal. pdf and that we welcome any comments from you.

The OSMF board has given us permission to go ahead with the formal OSMF member's vote once we have cleared this up; specifically, to work on what will be presented to OSM contributors assuming that you vote yes to the license change. You can see a snapshot here: http://docs.google.com/View?id=dd9g3qjp_28dgkdmhhq (sorry, it is not on the Foundation wiki yet!). We continue to refine it and welcome comments. We are also working on a Backup Policy, i.e. precisely what will happen to data of contributors who refuse to accept the new license. We will put that out for your review very shortly or you can read our early analysis in our meeting minutes [1].

> The License Working Group, with the approval of the OpenStreetMap Foundation board of directors, will be shortly asking the full membership of the Foundation whether or not to upgrade the license under which OpenStreetMap geodata is released from Creative Commons Attribution Share-Alike 2.0 to the Open Database License 1.0, an attribution, share-alike license specifically designed for databases. The license change also includes a new formal set of contributor terms. This is the key Go/No Go for the new license.
> Assuming that you vote yes, there will begin a process of requesting OSM contributors who have already made contributions to consent to re-licensing them under the new license. We currently aim to complete that process 26th February 2010, after which the newer version of the database will only be available under ODbL 1.0. Older versions of the database will continue to be available under CC BY SA.
