从开源创建软件衍生作品 [英] Creating software derivative works from open source

问题描述

这个问题一直困扰着我.

This question has always been around my head.

有人可以根据现有的开源项目创建新产品吗?

Can someone create a new product based on an existing open source project?

假设您要创建一个基本上是Apache的"Apaxe Web服务器"，并带有一些额外的插件(例如，对ASP或类似内容的支持)

Say you want to create an "Apaxe webserver" that is basically Apache with your some extra plugins ( say support for ASP or something similar )

这可能吗?

您能否创建封闭源产品(免费或许可的产品)

Would you be able to create a closed source product ( either free or licensed )

至于GPL似乎很清楚，这是不可能的，因为源应该是开放的.但是，Apache许可证，BSD和其他企业友好型"软件又如何呢?

As for GPL seems clear it is not possible because the source should be open. But what about Apache license, BSD and others "corporate friendly"

价格(对于大多数项目是免费的)，错误修复以及与核心开发团队一起计数是唯一阻止其他人将这些OS产品商业化的事情吗?

Are the price ( free for most of the project ) , bug fixes and counting with the core development team the only thing that prevent from others to commercialize those OS products?

那又如何:Khrome是基于Chrome的具有ActiveX支持的商业产品(谁敢做这样的事情:P)

What about: Khrome a commercial product based on Chrome with ActiveX support ( who would dare to do such a thing :P )

编辑

谢谢大家的回答.

那么，再次

是什么阻止类似(克隆)产品出现在市场上?

What prevents from similar ( clone ) products from appearing in the market?

:)

注意:我知道我们不是律师，我们可以在这里阅读每个OSS许可证 http://www.opensource .org/licenses .

推荐答案

没有什么可以阻止克隆产品出现在市场上的.例如，查看所有各种Linux发行版. X.org项目是从XFree86分叉的.依此类推.

Nothing prevents clone products appearing on the market. Look at all the various linux distributions, for example. The X.org project was forked from XFree86. And so on.

由于以下几个原因，它相对不经常发生:

It happens relatively infrequently, though, for a couple of reasons:

• 原始项目具有第一个进入市场的优势
• 通常会免费赠送原件

因此，除非您的版本明显优于原始版本，否则您不会从中获得很多收益或从中获利.如果您的版本好得多，请继续！

So unless your version is significantly better than the original, you're not going to get much uptake or make much money out of it. If your version is significantly better, then go ahead!

从原始开发者的角度来看，GPL的强大之处在于，它迫使此类克隆与世界其他地方共享任何改进，因此可以将它们合并回原始版本中.

From the original developer's point of view, the power of the GPL is that it forces such clones to share any improvements with the rest of the world, so they can be incorporated back into the original.
