The goal of the project is to utilize the next-generation HTML5 technologies to power the scientific and educational applications of the future. iChemLabs is dedicated to funding, developing and hosting this library and has released it for free under the open-source GPL license. By releasing ChemDoodle Web Components open-source, yet continuing to financially support the library, iChemLabs ensures that the next generation of scientific applications is easily achievable by academia, government and industry, and helps to make sure that the cost of education decreases while using the web to further spread science.
