JOELib

Developer(s)	JOELib development team

Operating system	Cross-platform
Type	Cheminformatics/Molecular modelling
License	GNU General Public License

JOELib is a free software chemical expert system mainly used for converting chemical file formats. Because of its strong relationship to informatics, this program belongs more to the category cheminformatics than to molecular modelling. It is available for Windows, Unix and other systems supporting Java. It is distributed under the GNU GPL.

History

JOELib and OpenBabel were derived from the OELib Cheminformatics library.

Logo

The project logo is just the word JOELib in the Tengwar script of J. R. R. Tolkien. The letters are grouped as JO-E-Li-b. Vowels are usually grouped together with a consonant, but two following vowels must be separated by a helper construct.
