The thesis - degree, specialization, master, degree certificate - is an original work and for this reason it must be protected by the law. The author of a thesis is the only one who holds the copyright and there is no binding force of the law between the thesis and the supervisor - first of all the publication right, linking moral and economical rights. A publication of a digital degree thesis by anyone must provide for a licence from the author self, because, if the digitalization is lawful with the object of conservation or of a usual procedure for administrative documents, a publication requires a licence anyway. The thesis is both an author's administrative document and an original work; this is the reason why it is treated under different points of view.
