We are planning to jump in OSM sea and want to mix some of OSM layers with some of our layers afterword want to build an application which will perform common GIS tasks. Now here are my questions.

Are we allowed to mix our layer and OSM layers in one application?

Where is the most appropriate place to mention OSM copyright info? If we include this info in the layer metadata, is that enough or we have to include this info in application as well? In other words where is best place to mention OSM copyright info?

Other than copyright info, is there any other requirement from OSM which we are missing?

Thanks in advance.

Taken from the OpenStreetMap License Page

You are free to copy, distribute, transmit and adapt our maps and data, as long as you credit OpenStreetMap and its contributors. If you alter or build upon our maps or data, you may distribute the result only under the same licence.

If you are using OpenStreetMap map images, we request that your credit reads at least “© OpenStreetMap contributors, CC BY-SA”. If you are using map data only, we request “Map data © OpenStreetMap contributors, CC BY-SA”.

Where possible, OpenStreetMap should be hyperlinked to http://www.openstreetmap.org/ and CC BY-SA to http://creativecommons.org/licenses/by-sa/2.0/. If you are using a medium where links are not possible (e.g. a printed work), we suggest you direct your readers to www.openstreetmap.org (perhaps by expanding ‘OpenStreetMap’ to this full address) and to www.creativecommons.org.

So I think the answers are, Yes you can use your data alongside OpenStreetMap, as long as you don't infer that your data is endorsed by OpenStreetMap. As long as OpenStreetMap are clearly acknowledged whenever there is an output. To be safe I would probably include it everywhere you can, it won't hurt, and anything that increases the profile of OpenStreetMap can only be a good thing.

More legal stuff can be found on the Creative Commons License Page

EDIT: In response to comment: From the OSM Wiki Legal FAQ

Can I charge for distributing OSM data or data derived from OSM data?

Yes. You can charge any amount of money you want for any service or data you provide. However, since the data (or service) that is derived from OSM data must be licensed as above, other people may then redistribute this without payment.

What I take from that is that any OSM or OSM Derived data you plan to sell could then be redistrbuted by the buyer under the same license. However any data that is yours or under a different license is not subject to this restriction.

What will happen, Am i allowed to sell this package commercially which contains OSM layers as well ours own layers and OSM layer contains proper copyright info on appropriate place. –  iRfAn Aug 13 '12 at 15:08
@iRfAn Please see Edit –  Rob Quincey Aug 13 '12 at 15:34
@iRfAn Also you should look back through some of your other questions and see if you can accept some of the answers as answers as currently you have a 0% accept rate, which often leads to people not bothering to answer your question. –  Rob Quincey Aug 13 '12 at 15:35
ahan thanks Rob point noted. –  iRfAn Aug 13 '12 at 15:50
