rabbitmq - licencia - ¿Puedo usar Mozilla Public License 1.1(MPL) en una aplicación comercial?



mpl licencia (3)

Hay un par de hilos que hablan sobre el tema de la licencia. Sobre todo centrándose en GPL / LGPL / BSD. Estoy tratando de usar RabbitMQ en aplicaciones comerciales, que está licenciada bajo la Licencia Pública de Mozilla (MPL). ¿Es MPL amigable para uso comercial?

Encontré una pregunta diferente en Stack Overflow, y uno de los comentarios menciona:

MPL: las personas pueden tomar su código, modificarlo, pero si distribuyen las modificaciones, deben asegurarse de que las modificaciones estén disponibles públicamente durante 3 años.

Si no toco el código fuente en absoluto, pero solo uso los archivos .jar en mi código, ¿también necesito licenciar mi código bajo MPL?

En un tono más serio, siempre debe consultar a su abogado, pero podría ser útil si lee el MPL 1.1 anotado en: http://www.mozilla.org/MPL/MPL-1.1-annotated.html pero básicamente significa que los archivos se pueden combinar con archivos propietarios en un "trabajo más grande", aún así, sería aconsejable que leyera la versión comentada y la consultara con un abogado.

No estoy seguro de si tiene dudas sobre la licencia de Apache ya que la menciona en el tema de la pregunta, pero no en el cuerpo de su pregunta.

No estoy seguro de si esto es lo que necesita, pero esta es la diferencia exacta entre las licencias de MPL 1.1 y Apache 2.0.

3.7. Obras más grandes.

Puede crear un Trabajo más grande combinando el Código cubierto con otro código no regulado por los términos de esta Licencia y distribuir el Trabajo más grande como un solo producto. En tal caso, debe asegurarse de que se cumplan los requisitos de esta Licencia para el Código cubierto.

No fue tan malo, ¿verdad? Parece que si todo lo que haces es vincularlo con el código, no es necesario que abras el código, pero debes cumplir con los términos de todas las cosas con licencia MPL cuando comenzaste.

Oblig "no me cites" un poco: de esa manera es algo así como la LGPL.
