Sobre la licencia de componentes FIBplus

[[rretamar]]

Si los componentes son libres, alguien puede subir los fuentes (que la empresa no proporciona) a las redes P2P (o a este mismo foro) y sería perfectamente legal.

Y hasta se podría hacer un "fork" con esas fuentes, y sin las limitaciones antes mencionadas.

Si los componentes son libres, alguien puede subir los fuentes (que la empresa no proporciona) a las redes P2P (o a este mismo foro) y sería perfectamente legal.

Creo recordar que son dos "units" las que no entregan con el código fuente, las dos principales , pero de todas formas, cuando pagas sí te lo entregan completo con todas las fuentes. Al menos antes lo hacían, yo tengo una versión un poco antigua y viene con todos los fuentes, no sé qué harán ahora.

[guillotmarc]

Pues la verdad es que yo no sé verlo. ¿ Alguien tiene su license.txt ?. En el código fuente de los .pas dice que leamos el license.txt para ver la información completa de la licencia.

Sin poder leer esa licencia no podemos saber a que atenernos. Puesto que si la licencia original es del tipo GPL, entonces todo trabajo derivado, por más modificaciones y ampliaciones que hayan hecho, tiene que ser forzosamente también GPL en todos sus módulos (no pueden esconder ni siquiera esas dos Units), y por tanto pueden cobrar por el empaquetado, servicio, etc. ..., pero seguiría siendo libre para quienes no quieran ese "servicio" de Devrace.

En cambio si la licencia original es del tipo MPL, tienen derecho a cerrar todo el código cuando quieran y solo tiene la obligación a informar de que es un trabajo derivado del de los autores originales.

¿ Alguien puede acceder a la license.txt de las Fibplus e informarnos de cual es exactamente la licencia que utilizan ?, si es posible sería bastante útil que la copiarais aquí.

Saludos.

La licencia la he sacado de esta web de los componentes.

Creo recordar que hace años, originalmente, era GPL, pero desde hace algunos años, "desapareció" el fichero de la licencia, curiosamente desde que FIBplus dejó de entregar los fuentes de esos ficheros que faltan [conspiranoic](¿algún acuerdo entre ellos?)[/conspiranoic].
Ahora la licencia es esa que he puesto antes, pero no viene junto al zip con los demás ficheros, cosa que tampoco es "normal".

Y esta es la licencia de fibplus en el 2001

----------------------------------
LICENSING INFORMATION
----------------------------------
The FIBPlus Trustware License is based on the Trustware License of CPS -
Computer Programming Solutions of Mesa Arizona USA.

FIBPlus is based on FIBComponents by Gregory Deatz ([email protected]).
The author of FIBPlus is Sergey Buzadzhy ([email protected]).

----------------------------------
FIBPlus is a trustware product
----------------------------------

FIBPlus is distributed in sources and we have no opportunity to control
completely how the library is used. It means that the use of the library mainly
is based on our trust to the FIBPlus users. But we permit generous registration
of various licenses which regulate the rights of the FIBPlus users.

----------------------------------
Evaluation License
----------------------------------

If you have an evaluation version then these files and any of their contents should be
redistributed only together in their original form.

Modifications must be approved by the Devrace company. The evaluation version may be
freely distributed without our permission but it can not be used for commercial purpose
(that is for getting profit).

We want to encourage the distribution of the evaluation version as much as we can.

----------------------------------
Registered License
----------------------------------

Registration of a purchased license is valid only for the developer in whose name the
original registration was made or, in a case where ownership was transferred, the
developer to whom it was transferred. Site licenses may also be negotiated at substantial
savings to cover departments or small organizations.

If there are other developers in your organization who will use the source or components
please ensure that each individual has a license properly registered to his or her name.

You can not use FIBPlus as a base for products which may be considered to compete with
FIBPlus in some capacity. Please contact the Devrace Company if you have any
questions regarding this.

By purchasing commercial license the developer gets a right for commercial use of FIBPlus,
its new versions and changes realized during one year after registration. That is all new
versions and changes realized during one year after registration automatically become
registered. The commercial use of the registered copy is limited by the terms of this
license and can last for an unlimited period. The developer also gets special discounts
for prolonging the term of the license. Please contact the Devrace Company if you have
any questions regarding this.

----------------------------------
Free Licensing
----------------------------------

We permit generous registration of various free licenses. The concept is that all who use
FIBPlus for commercial purposes, including as employees of a company that engages in
developing products or services for in-house or commercial use, who do not in some way
contribute to the FIBPlus product, shall be required to purchase licensing for commercial
use. All others may inquire about being granted a free license.

We may permit a commercial license to be registered free of charge, until the project turns
out to be profitable, at which time the license would be purchased after the fact. If you
can't make a profit using FIBPlus then we don't feel you should have to pay for it.

There is no charge for access to these components and their sources for those who will not
be profiting financially by their use or for those who are contributing to it. For example,
this may include but is not limited to:
* People wanting to extend their skills in their free time.
* Students or instructors wanting to use them for educational curriculum.
* Non-profit organizations.
* Religious organizations.
* Open source projects that are not geared towards returning financial profits to their
developers, either directly or indirectly.
* Individuals or organizations contributing support in the various public forums, bug
cases and fixes, enhancements, new components or controls, sample applications,
tutorials, "How To ..." articles, marketing materials for promoting FIBPlus, etc.

----------------------------------
Disclaimer
----------------------------------
These tools are distributed AS IS for use at your own risk. No damages as a direct or
indirect result of using this product can be claimed or litigated against the provider.

2001, Devrace Company

No me aclaro mucho con esas licencias que utilizan en las FibPlus antiguas.

Pero sí que resulta bastante clarificador que las MDO tengan licencia MPL.

http://ostatic.com/mdo

Eso quiere decir que la licencia original de las FreeIbComponents era MPL o compatible con ella, puesto que de una librería GPL no se puede hacer un derivado MPL.

Por ello, si la licencia original era MPL, entonces tal y como lo entiendo yo, Devrace tiene todo el derecho a modificar el código y distribuirlo con una licencia propia, comercial, su única obligación es la de que se informe claramente de que se ha usado el código original MPL. Poco más o menos lo que hicieron los chicos de Yaffil con su fork comercial de Firebird (la licencia de Firebird es compatible MPL).

http://es.wikipedia.org/wiki/MPL

Tiene sentido, ya que si la licencia origianl fuera GPL (y por tanto FibPlus también fuese GPL), entonces no lo podríamos usar para crear nuestro software comercial. Ya que interviene el famoso efecto "viral" de las licencias GPL, y cualquier código que esté linkado con al menos un módulo GPL (en este caso las FibPlus) también tiene que ser liberado bajo GPL.

Parece que los de Devraces actúan de forma perfectamente legítima, aún así resulta curioso el ocultismo en sus últimas versiones. No he encontrado ninguna licencia ni en FibPlus 6.9.6 ni en FibPlus 6.9.9 (en esta última ni siquiera publican nada de código fuente).
