What is meant by “to have acquired the basics”?
Whatever his or her work environment and speciality or profile, a professional must know the terminology of the profession and be able to put a name on a certain number of essential subject matters (e.g. types of documents), of techniques (e.g. subject indexation) or tools (e.g. classification scheme) and to provide the commonly accepted definition of these elements. He/she must also be able to show awareness of the main rules of the profession (specifically, standards). Generally, all this is acquired through professional training, reading, attending lectures etc.
