The license requires a particular form of attribution and some other conditions, which they claim are compatible with CC-By. But before we get all enthusiastic about importing or tracing things, I think we need to consider the implications of their licence. My reading is that it would require us to include their attribution statement on any product that uses the data, which would include downloads and OSM's slippy may. It may or may not be enough to link to a "sources" wiki page from the OSM copyright line. More importantly, we also have to ensure that any downstream users are aware of the OS data included, and also ensure that our terms require them to include the OS attribution statement. I don't think the current OSM arrangements would satisfy these requirements, and I'm not sure the viral copyright attributions are something we would really want to accept. I could imagine a point where to print a small OSM derived map in a paper publication would mean including half a dozen copyright lines that would take up more space than the map itself. Moreover, since IIRC ODbL allows rendered maps to be made PD (or any other license) and also allows small data extracts to be used without restriction, I'm not sure that we'd able to use the OS data under their current license if/when we move to ODbL. Until we get clarification on these issues, I'd suggest not importing any of the OS data, or using any of it for tracing.
