Hi there, according the the Community Guidelines for Horizontal Map Layers, feature overlays have to be released unter ODbL, if they're completing content on an online map.
Quote from http://wiki.osmfoundation.org/wiki/License/Community_Guidelines/Horizontal_Map_Layers_-_Guideline "For example, if there are restaurants in the OpenStreetMap layer and you add additional restaurants in another layer, but you include only those restaurants not present in the OpenStreetMap layer so that the restaurant layers will complement each other, then the layers for this feature are interacting and the restaurants added in your non-OpenStreetMap layer must be shared." This would mean: If I show parking facilities for bikes as an GPX or GeoJSON overlay as a layer an top of the OpenStreetMap base tiles, which might already included existing facilities, I'd need to publish my overlay under ODbL? This guideline takes clause 4.5(b) as a background. This clause is for produced works only... Does this clause even work for overlays? Also the examples shown below on the page aren't pretty clear either: "If you improve data used in the OpenStreetMap layer, such as additions or factual corrections, then you need to share those improvements." => So this example is for the OpenStreetMap layer only. I won't touch it. "You add restaurants in one area from non-OpenStreetMap data based on comparison with OpenStreetMap data in other layers." => What if I don't run a comparism before? Perhaps it's fortune. "You add a non-OpenStreetMap cemetery layer that is defined as 'all cemeteries not found in the OpenStreetMap data layers'." => What if I don't explicite tell that those data is missing?
