Starts with an O, but it just isn’t it

We believe it is every person’s duty (as tribute to the professors and mentors in his profession) to share his knowledge, to make it widely available and to accept debate. The debate is her/ his reward, her/ his chance to capitalize on the opinions given back and eventually, to enlarge and improve his own knowledge and his own “product”.
The most common examples of freely sharing creations are the books in a library or the paintings and sculptures in a museum or music sang at the opera. As I don’t want to get confronted with the intellectual fundamentalism, I will also mention other forms of sharing the source of a creation: aspirin or the popular automobiles. I would add that, at least in the IT industry, the open source products become eventually a collective creation, where contributors offer their own expertize, in the most varied competence areas.
