Hi, indeed great to see you reach out. Yes I agree that a good approach is to make the data open. However, I understand Greg is asking if there are working concepts on how to maintain a link between local government GIS (which might have additional information) and OSM data. Once the relevant information has been entered into OSM, how is the council to track the data? e.g. to see if tags get modified, nodes moved, added. e.g. worst case is that a nicely mapped and tagged area gets re-done by someone. This results in new node and way numbers. A good example would be a single node gets expanded by OSM users. In both cases the data is diverging from another. How to keep track? Are there concepts/solutions? Yes
