The RCSR partially overlaps with the larger EPINET database which contains, among other data, 14,532 stable 3D nets, which we processed similarly. Finally, both databases partially overlap that of Structure Commission of the International Zeolite Association (IZA-SC) , which provides names for 255 zeolitic framework structures and corresponding CIF files. These structures have unambiguous vertices, defined by the tetrahedral atoms, and edges between two such atoms bonded by an oxygen, thus a uniquely-defined underlying net.
