Mmm, careful with your language, John. The data "have a license which is compatible with OSM's ODbL" (is an accurate way to say it). I believe that took about eight years and was a difficult slog, a lot of hard work by many, lessons learned from Ottawa, a determination by OSM's LWG, but it is done. (I am grateful for that, it is an important milestone).
A different issue is whether the data and their concomitant quality "are acceptable" to the OSM community. The license being ODbL compatible is not that; these are different issues. We now discuss data quality (and what to do to improve them, if anything) here in talk-ca and in the mildly-being-updated Import Plan, with experiences of what Yaro, Danny and Nate have done in Toronto. It is not the case, as John says, that "the data (are) licensed to be acceptable to (OSM)." The concept of "acceptability" is not related to the data being licensed compatible with ODbL. What often/usually happens is an Import Plan gets wide vetting and acceptance by the OSM community before data become imported, including suitability/acceptability of the quality of the data. What happened here is the Import Plan was attempted to be widely vetted, but this seems to have been largely ignored or little-paid-attention-to. While the Plan's initial shortcomings were pointed out, yet not remedied, the Import began, then the community began to react (with some complaint and some "what Yaro does seems OK"). Yaro (and Nate, I believe) then updated the Import Plan with Yaro's specific technical steps. Still, complaints and/or disagreements about simplification, squaring and potentially other issues continue. (As two asides, I'll say that MANY buildings are not necessarily "square" — like buildings with bay windows — and that truly square/rectangular buildings should express this with a tagged way/closed polygon made up of exactly four nodes). As these discussions continue, eventually what will emerge is "how do we (algorithmically, manually...) change the data, whether pre-import or during-import, so that they achieve wide acceptance as to their quality by the community." We're getting closer, it seems to me, but I don't think we're there yet. Nobody seems to be arguing there is or isn't a "desire to bring in the buildings by many" or to "use them for many purposes." That point seems "decided." The questions remain: "how, with the existing data?" Once those are determined (and documented in the Import Plan), over time, the data will (or will not) be imported. I wish to offer encouragement to this process, it does appear to continue here and can likely bear fruit in the near future. Keep going! Consensus is ahead!
