A brief history
In 1996 Luc Patiny founded a Belgian company, ChemExper sprl, that allows to search for free for commercially available chemicals. It was providing the first substructure search engine on the internet in which you could draw, thanks to a java applet, a chemical structure.
This first search engine was done using
4D search engine and at that time even the HTTP server had to be developed using direct access to a TCP library. In 2000, we have also published in a journal that disappeared in the meantime ... a way to share spectra directly on the internet.
Later this search engine has been rewritten from scratch in Java and since 2005 research data from the institute of chemistry of the University of Lausanne were stored in a MySQL database. At the beginning it was only possible to store mass spectra, NMR spectra, infrared spectra, ultraviolet spectra, circular dichroism, x-ray structure and chromatography. All the data were converted before importation to the IUPAC supported format: JCAMP-DX.
On first January 2008 over 10'000 samples were already created in this database.
This project grew, and we quickly reached over 100'000 samples in the database. It was based on one big project that became difficult to maintain and to develop. Moreover, we wanted to have the same code in the browser and on the server and with the disappearance of Java applets it became impossible.
Based on those basic building blocks various more advanced projects were achieved. The best known ones are
