JOELib is computer software, a chemical expert system used mainly to interconvert 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 operating systems supporting the programming language Java. It is free and open-source software distributed under the GNU General Public License (GPL) 2.0.

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.
