Term of GNU General Public Licence version 2

[netops]

Hi,

We are using OpenKM-Community Version 6.3.0 on Centos 6.5 x86_64 Bit OS.

We are finding some limitation with provided flexpaperviewer/zviewer that comes with bundled application. Here we want to use other viewer that could be a customized as per our requirements.

Could you please confirm the licensing terms whether it breaks any terms of GPL GNU if we use OpenKM community version with own viewer.

I will move further after your clarification in term of licensing for proposed configuration.

Kindly feel free to revert in case further information needed from my side.

Thanks

Consider the viewer as a module in the OpenKM not part of OpenKM core. You integrate with thirdparty applications ( in this case into iframe etc... ) that not breaks GPL v2 licensing. For example you can consider integrate into OpenKM a new tab with and iframe which makes a remote call to a viewer or whatever be, that not means this is yet a part of OpenKM. Us for example we are integrating commercial thirdparty visors, these goes as an additional module not a part of the OpenKM.

Do not worry is possible integrate commercial software with open source, and the commercial software it not becomes open source.

The philosofy of the open source is, not selling ( but you can offer support ), when you add new features ( I'm refering about code ) these becomes open souce, but in the scenario you write code with access a library ( the library is not becoming open source ) also if you integrate a visor the code for the integration should be open source but not the visor.

Hope it can help you. What are you thinking to being integrated or integrate into OpenKM. We can guide you in a way you create an OpenKM frontend extension which could be enabled or disabled ( in this scenario can be included in the openkm community source code ).
