Hi Joining the conversation late here, but I assume this dataset is property boundaries. I can understand why you wouldn't want the boundaries themselves moved, but what about the case where we want to build upon the boundary data? For example, a simple case might be: this bit of boundary is a hedge. I might then want to split a way that's part of the boundary dataset, and mark a section of it barrier=hedge. Doesn't sound that unlikely, nor that unreasonable.
The fact that the boundary data would be in OSM would be valuable, but to prevent anyone building upon it would undermine that usefulness. Are we planning to import this dataset to give us raw data to build upon, or is it just to store a copy of someone else's untouchable data, in which case, what do we gain? We don't claim any of the data in OSM is 100% correct, certainly we don't claim that the OSM data is the definitive, legal definition of the world; I'm assuming we won't be claiming to be the definitive source of the DEC Lands dataset, nor feeding back into their dataset... so what's the worry? Why should we be more worried about this dataset than, say, the exact positioning of the road network?

I propose importing the NYS DEC Lands as an immutable set of data. If you read this exchange with Robert Morrell, you can see why they feel that NO changes AT ALL are appropriate. I agree with them. This dataset constitutes a legal description of the property managed by the NYS Department of Environmental Conservation, and changes by any OSM editor are not consistent with the nature of the data. How do people feel about me importing this data (with all of their metadata), adding an immutable=yes tag, with the intent of tracking their dataset, and deleting --outright-- any changes made by OSM editors. _______________________________________________ talk mailing list talk@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk
