BODR is the "Blue Obelisk Data Repository". It represents a set of common, standardized data for chemoinformatics in both XML and plain-text formats. Currently this encompasses: 1) Elements directory - element names and symbols - atomic masses, covalent radii, van der Waals radii - Pauling electronegativities - electron affinity - ionization potential - default element colors for viewers 2) Isotopes directory - exact masses of most abundant isotopes - isotopic masses and abundances - spin - kinds of decay, percentages and energy - magnetic dipole moment - halflife
