Could you please suggest which are the well-known "open source" licenses allowing me to use libraries under these licenses in proprietary webservice (accessible in Internet to the public), which I am not going to make opensource.
I am ok to state somewhere that I am using the library, and I am ok with sharing the changes I make in the library.
I guess GPL ones does not work here, as I am not going to release whole product as GPL, what are other options?
That's what I've found about Meebo & libpurple:
I have a licensing question. Do you guys feel that Meebo's use of libpurple is acceptable given the GPL status of the libpurple codebase? According to a post on the Meebo website, they feel that they are not required to release their source code because they do not directly distribute binaries to customers (since Meebo is a web application). The reason that I ask is because I am thinking about starting a project using the libpurple codebase and I'm wondering what the licensing restrictions would be.
And the libpurble developer replied that it's ok :-S
Also, I've found this:
The loophole referred to is that an “Application Service Provider” (hence “ASP”) gains the benefit of the freedom of a copyleft license, by running the program and (presumably) gaining whatever benefits come from having people access the running program across the network; but the provider can argue that they themselves are not redistributing the work as such, so they are not obliged to offer recipients the same freedom.
That says that we can use GPL v2 & v3 code in web services while we are not distributing the application itself (for example like google does). Is that correct?
