OpenSource, OpenData and OpenStandards are not as strong in chemoinformatics as they are in bioinformatcs, where it is common knowledge that sharing is a good.

Several open source projects participate, amongst which the CDK, Jmol, JOELib, OpenBabel, Chemical Markup Language, Bioclipse and Kalzium.
