Abstract. Human beings have always sought solutions to their problems to sustain life, albeit with an in exhaustive efficiency. As Corona overran the world, educational institutions had sought alternative methods of traditional education, and found no way to do so except by teaching online. Several educational institutions in the world have paid great attention to this method, years ago. The subject is the application of the program of the ]Open Educational sources[ launched through the Budapest Initiative in 1991. The initiative calls for the unhindered availability of science and information to all people, followed by the Massachusetts Institute Initiative in 2000, where all its educational work was published free of charge online and then successively until the UNESCO meeting in 2002. The participants agreed to use the term "open educational materials". The conference was held in Paris in 2012 and is recommended for the formal adoption and adoption of the program by the organization, recently adopted by ISESCO. The program aims to find an alternative to traditional education by publishing free curricula in the various disciplines on digital repositories and then on the Internet platform, under simple conditions. To illustrate this subject for those who have not already been familiar with it. I introduce this paper from my experience through the attending of several workshops adopted by UNESCO, which is a model of a descriptive document of a curriculum in pharmacology science, which can be released to the university's digital repository and made available free of charge.
