There is a very good and widely used library called PROJ.4 (libproj or
libproj4) that touches this subject:
Recently, OSGeo Foundation has launched new initiative called MetaCRS.
Details are here:
I believe it would be highly beneficial if potentially new project
Boost.Geodetic was interested in collaboration with OSGeo Foundation.
The OSGeo can provide professionals experienced in development of such
