Yes surely that is the situation - use the source tag when using something other than gps. I have accepted the ToC, TBH I really don't give a monkeys either way though have something of a preference for PD as it keeps life simpler, and I believe the small minority of OS OpenData I have contributed has source=OS OpenData or some such.

What I meant was that, as I understand it, there is no particular licensing requirement that every node/way derived from a CC-by-SA source must have a source= tag on it (as Steve Bennett seemed to be suggesting). My understanding is that the overall attribution on the Contributors page is sufficient. This certainly intuitively fits with other CC-by-SA projects. For example if you use some CC-by-SA source code then you don't need to add an attribution comment on every line of code - you just need one somewhere prominent. -- View this message in context: http://gis.638310.n2.nabble.com/Can-I-say-yes-to-the-ODbL-if-I-can-t-account-for-100-of-my-data-tp6481040p6483737.html Sent from the General Discussion mailing list archive at Nabble.com. ___ talk mailing list talk@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk

I also frequently use multiple sources in a single changeset. I often flip between faster bing imagery and slower to load but better aligned and sometimes more distinct NAIP imagery. Which one I actually trace a feature from depends on multiple factors. Hence I often put source tags on individual objects.

I put a source tag on every single object I create, and try and update it when I modify it. It is not completely useless but I observed that in general the more versions an object has, the less reliable the source tags on it are. Maybe you are an exception and do update every object you touch and you verify always the source on it, but most mappers actually don't. IMHO changeset comments really don't work well (in Potlatch at least), it depends how often you upload. For small edits where you just enter that place you have recently been to, I find them perfect. Bigger edits will usally get more generic comments, but when tracing from aerial imagery I include the provider and if known the year of the images. and it's far too easy to include the wrong objects in a changeset. either way you can miss some parts of your edit. cheers, Martin ___ talk mailing list talk@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk

IMHO this is where this belongs to. AFAIK the source-tag is disputed and it is recommended to use the changeset comments. Source is disputed? By whom? I've never heard any dispute about it? Source is very much alive. It has been suggested to use the source tag on the changeset instead of every single object edited within that changeset, but it's admittedly still mostly used the traditional way. I put a source tag on every single object I create, and try and update it when I modify it. IMHO changeset comments really don't work well (in Potlatch at least), and it's far too easy to include the wrong objects in a changeset. I put source tags on changesets now. Source tags on objects tend to get outdated, and I find updating all these tags painfully tedious. When you add new objects, it would at least still possible to mass tag them with your source, but that isn't possible when you have to insert your sources into an existing source tag's value. It seems like unnecessary effort, too, because I tend to group my edits into sensible changesets anyway and rarely use more than one source for each changeset. In my opinion, changeset-based sources also make it clear which edit was using which source. For example, since good Bing imagery has become available, I've developed a habit to trace the buildings in an area from Bing, then go out and survey the area in order to add house numbers and other attributes to the buildings (and make sure that the imagery wasn't bogus). This means that I will upload two changesets: One based on Bing, one based on survey. Looking at the history and the source tags on changesets makes it completely clear what data originates where. This wouldn't work with a source tag on the object: A source=Bing;survey does /not/ tell you that addr:housenumber=72 was surveyed and roof:color=red was determined by looking at Bing images. -- Tobias Knerr ___ talk mailing list talk@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk
