PlantUML license

Question

I have two questions:

1- Regard the binary file of PlantUML.jar, Is it possible to redistribute the LGPL one and if there any constraints about it?

2- What is the liceense of the PlantUML syntax inside the code? If I wrote some of the PlantUML syntax as a comment inside my code then is it mandatory that my code should be under GPL ?

 

Thanks in advance

Answer 1

The FAQ ( http://plantuml.sourceforge.net/faq.html ) have been updated about this :

As long as you do not modify the Java source code and the LGPL  jar file, you can integrate PlantUML.jar in your own closed source software.

The only constraint is that you have to mention somewhere in your own license or in your documentation that you are using PlantUML and that PlantUML is distributed under LGPL.

About the license of the PlantUML syntax, there are no license for the PlantUML syntax it self : this means that everybody can use it.

So you can use PlantUML comments into your own code : those comments are owned by yourself, and are not considered as covered work, and are not covered by the GPL/LGPL license.

Only the current implementation (that is, PlantUML program) is licensed under GPL or LGPL.

If you have remarks/question, please go on.
