JOELib is a freeware 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.
