We are not in the same situation as decades before when the well-known databases (ICSD, CSD, PDF) started. Today we have the Internet, fast computers, and a big pool of free available software. The question is: do we have enough scientists who are willing to cooperate?

We realize that the Subversion software may be unsuitable for some of the COD users. Thus, we provide essential COD data via different protocols. Coordinates and structure factors can be accessed using Rsync tool at URIs rsync://www.crystallography.net/cif and rsync://www.crystallography.net/hkl, respectively. CIFs can be downloaded and later updated from these read-only sources. Examples of commands to download the COD file collection and to search the COD file tree for the required files is provided in the Supplementary files.
Even without 100% coverage of all known compounds (and elements), COD can be used for gathering statistics about chemical and structural properties of organic compounds, assuming that the COD has a representative subset of the compounds of interest. Since the COD may be accessed and downloaded free of charge by universities and students, the COD can also be used for teaching, providing a real life and high volume example of a scientific database for formulating challenging tasks in data mining and processing. 2ff7e9595c
