Licenses of Software

 Distribution Licenses

The license for use is a document that accompanies the software and specifies the rights and duties of those who receive it and those who disseminate it.

All user licenses derive their legal value from the copyright laws (copyright).

There are free licenses, open source licenses and proprietary licenses. Later on, also the open content was born, which aims to transfer licenses to works other than software.

There are numerous licenses for using and distributing free and open source software, but those that are actually widespread are few. For 89% these are GPL, LGPL and BSD (historical license of Unix, returned to use since the advent of Linux).

Some free licenses:

GNU-GPL (the most widespread free license)
GNU LGPL
BSD
Creative Commons
Each type of license differs from the others in various aspects.

Copyright

As expressed in articles 1 and 2 no. 8 of the Law on Copyright (L.633 / 41) also the computer programs are protected by copyright in any form expressed as long as they are original. The preparatory material is also protected unlike the ideas and principles that underlie any element of a program (including those at the base of its interfaces) which are not protected.

According to article 12 bis of the aforementioned law, in the case of commissioned work the owner of the exclusive right of economic use is the employer. However, this does not detract from the moral rights of the person who created the code, or the employee.

Exclusive property rights:

Publication (article 12 of the LDA)
Total or partial permanent or temporary reproduction of the computer program by any means or in any form (article 64-bis letter a, article 13 LDA)
Modification (article 64-bis letter b, article 18 of the LDA)
Distribution (article 64-bis letter c, article 17 of the LDA)
Rental and loan (Article 18-bis)
Execution and representation in public form (article 15 of the LDA)
Communication to the public (article 16 of the LDA)
