Re: [xmlvm-users] Publishing XMLVM applications

[Arno P. <ar...@pu...>]

any license imposes rules that you will have to follow. One aspect that 
I personally like about the GNU type licenses is that it imposes a 
"community aspect": if you make a modification, you need to contribute 
this back to the community. BSD does not impose this. You might argue 
that it is in a developers best interest to contribute modifications 
back in order to stay in sync with the main trunk. This is certainly 
true for small patches/fixes, but I would also like to impose this for 
new modules that the developer might decide to withhold for competitive 
reasons.

There is a bit of a mentality out there that Open Source just springs 
into being and free for anyone to use. A GPL-type license is just a 
little reminder also to give back.

Well, I suggest to tackle the problems as they arise. As Sascha pointed 
out, we do want you to be able to use XMLVM for your proprietary 
products. Just don't forget that someone has to do all the work and 
perhaps think of way to participate in the community.
