Therefore, in a last task, the topological genome of each net is compared to the existing databases of named topologies: the Reticular Chemistry Structure Resource (RCSR), the EPINET project, and the zeolitic nets from the Structure Commission of the International Zeolite Association (IZA-SC). The nets who have been attributed a name (often a three-letter code) by one of these entities can then be referred in a more human-readable fashion: dia for diamondoid net, SOD for sodalite zeolitic framework, etc. For nets that are not in any of these databases, we call them unnamed : they are uniquely identified by their genome, but they have not been attributed a name.
