My experience is that the LWG never makes definitive statements! I suggest that you turn the tables on them and send them an email saying that you will import the OGL-licensed data in xx days unless you get a statement from them in the mean time saying that it would be violating the OSM licensing terms and compromising your status as a contributor. Fyi, I was at a meeting where Francis Maude, the cabinet office minister, spoke about open data recently. He is very keen or this sort of use and is pressing for more data to be released and used. In light of that it would be a brave or foolish council officer who challenged such an import! Regarding data formats. Can I suggest that that we gratefully accept data in whatever format it is provided. We can ask politely for it to be in an better format but please don't complain either about the quality of the data or the suitability of the format which may support councils who will argue that they should delay releasing anything until they have got it right and in the perfect format. The phrase is 'raw data now' (warts and all). On a separate note. Would you be able to do a comparison between place names in NatGaz and in OSM. I think we will be surprised how many places we are still missing from OSM. My guess is that OSM only contains about 65% of the 50K places in that database.
