It is likely that they can carry the information about the conditions in the early state of the evolution of the protoplanetary

disc from which planets are formed. This collection of systems containig planets in or close to the mean-motion resonances will be a starting point for a living database of the complete data on systems which possess this interesting property and will be helpful in uncovering the processes responsible for the diversity of the planetary architectures.
