Multiple edition and restriction edition

Hello OpenStreetMap Community,

• I have created a map with several layers (line colors and line shapes for the legend/chart) that I would like to be fully published on OSM, but with its edition restricted to me only.

Let's say it would be the restricted base map.

• I would then like to enable people to make additions to the restricted base map, without allowing modifications on it, but only allowing to add more elements using the same legend/chart as the base map. (Can they have access to the chart but not the map edition?)

• As more users would add elements to the map, it is important that each one of them can make additions, but WITHOUT modifying the additions of another user, comments on each others additions would be allowded. (Exemple: UserA can draw a lineA, and UserB can draw a lineB, using the chart of the not editable base map, but UserA can't modify lineB, UserA can only make a comment on UserB's line). Is it possible to create such a "multiple users" map ?

• Can this map be then published with an external link on another webpage ?

Thank you for your help and attention on this issue, I am looking forward to reading you, Regards,
