We are currently changing the license, [[License/About The License Change|read more about it here]]. If fully accepted by our community, data will be re-licensed under the [http://www.opendatacommons.org/ OpenDataCommons] [http://www.opendatacommons.org/licenses/odbl/ Open
Both licenses are broadly the same, you can use the data without payment, provided that you "Attribute" and "Share Alike". However, the new license is specifically written for databases. It offers our project more protection. Attribution is more practical. It is a lot clearer on when "Share Alike" is triggered. It also
'''Legal Bit!''' Please note that none of this is legal advice. Additionally, under "CC-BY-SA", the individual contributors, not the Foundation, are the licensors of the data.
==Is it really free?==
== How should I attribute you? ==
Under the current CC BY SA license, there is no clear guide as to how attribution should be made. However, a community consensus can be found [[

We suggest the following:
* If you are using OpenStreetMap '''data''', we request that your credit reads at least "''''Map data (c) OpenStreetMap contributors, CC-BY-SA''''".
* If you are using OpenStreetMap '''map tiles''' (e.g. Mapnik or Osmarender/tiles@home), we request that your credit reads at least "''''(c) OpenStreetMap contributors, CC-BY-SA''''".
=== Where to put it? ===
Under CC BY SA, the attribution needs to appear in a place "reasonable to the medium or means you are utilising". In other words, you should expect to credit OpenStreetMap in the same way and with the same prominence as you would any other map supplier.
The common OpenStreetMap community interpretation of this is:
* For a '''printed map''', the credit should appear beside the map if that is where other such credits appear, and/or in the "acknowledgements" section of the publication (often at the start of a book or magazine).
* For a '''browsable electronic map''' (e.g. embedded in a web page or mobile phone application), the credit should typically appear in the corner of the map, as commonly seen with map APIs/libraries such as Google Maps.
* For a '''tv production''', the attribution should typically appear in a corner of the map. As long as the credit is on screen long enough to be read, it does not have to remain in view during panning or zooming.
* As an '''electronic database or collection of databases''', TO DO.
