When we speak of authorship, we refer to who has the status of author, a termination that comes in its etymology from the Latin "auctor" whose meaning responds to promoter or instigator. At the same time, it comes from the Indo-European "aug" which can be translated as increase.
Authorship applies to someone who is recognized as the playwright, author or director of something, not always his own. Thus, for example, we can speak that the authorship of the book "Martín Fierro" is given to José Hernández who has been its creator, as well as the authorship of the renowned work "David" corresponds to the painter Miguel Ángel. In this order of ideas, we can also say that the authorship of a crime, a robbery or a rape, it is up to those responsible for his despicable actions.
In Criminal Law, the authorship of the illegal act typified as such in the rectitude and compliance with the laws of the country, is attributed to the person who committed it directly, not presuming such a circumstance as it must be proven; others being guilty as accomplices or accessories.
In legal works, such as someone who writes a book, a musical score, a script for the seventh art, develops a system or who paints a box or performs any type of unpublished cultural or artistic expression, or perfects something existing in an innovative way, has recognized and has earned its authorship, which in order to avoid being debated or taken away, it should be registered in a special registry to be able to enjoy its copyright., which includes profiting from it, reproducing it, exhibiting it, etc. If someone wants to use it, for example to acclimatize the content of a book to the cinema, they must request permission from its author. The copies of artistic works, especially cinematographic or musical, through the so-called “pirate copies”, even when they are common practice, are strictly prohibited and those who commit this crime suffer serious judicial consequences that involve from fines to years in prison.
In cases where a work or event has been made by more than one author, the work is said to be under a co-authorship. Likewise, when the identity of the author is not known, the work is considered to have been created by an "anonymous".
