There is a point that, in my opinion, is not quite emphasized in the context of general relativity. It is the notion of spacetime coordinate systems that from the very foundation of general relativity are assumed to be all on the same footing. Nevertheless I believe each of them has to be specified by an "operational procedure" at least from a conceptual point of view. Otherwise what could be the meaning of coordinate values for a given event ?

Consider for instance the Schwarzschild metric where the metric tensor is defined in an (implied) coordinate system for the (curved) spacetime. In that case which is (at least from a conceptual point of view) the operational procedure to follow to assign Schwarzschild coordinates to a generic event ?

Thanks
