5. Because we can not afford to work

for two months and not be paid now!

Disclaimer

• The practices recommended here are

applicable only to Spain, as far as my

experience goes.

• Hopefully this won’t be neccessary

beyond our frontiers…

Drupal license

• Drupal and all contributed files hosted

on Drupal.org are licensed under the

GNU General Public License, version 2

or later.

1

Drupal license

• That means you are free to download,

reuse, modify, and distribute any files

hosted in Drupal.org's Git repositories

under the terms of either the GPL

version 2 or version 3, …

2

Drupal license

• …and to run Drupal in combination

with any code with any license that is

compatible with either versions 2 or 3,

…

3

Drupal license

• http://drupal.org/licensing/faq/

• http://www.gnu.org/licenses/old-

licenses/gpl-2.0.html

4

PHP and else...

• We require that all files (PHP,

JavaScript, images, Flash, etc.) hosted

on Drupal.org be under the GPL. If it's

in Git, then it is under the same

license (GPL version 2 or later).

Source code

• …the PHP file itself, without any compression or obfuscation, is its own source code. Note that for Drupal, template files are PHP code.

• …the JavaScript file itself, without any compression or obfuscation, is its own source code.

• …the CSS file itself, without any compression or obfuscation, is its own source code.

Image files

• For images, the "source code" varies.

Depending on the image, that could

mean the production version of the file

as a PNG or GIF, or an original high-

resolution JPG, or a Photoshop,

Illustrator, or GIMP file. The "source

code" is whichever version is intended

to be edited by people.

Flash files

• For Flash files, the source code is the

editable FLA and AS files, and any

other files needed to build the final

SWF. The SWF file itself is the "object

code" version, not the source version.

My work

• If I write a module or theme, do I

have to license it under the GPL?

• Yes. Drupal modules and themes are a

derivative work of Drupal. If you

distribute them, you must do so under

the terms of the GPL version 2 or

later. You are not required to

distribute them at all, however.

1

My work

• If I write a module or theme, do I have to give it away to everyone?

• No. The GPL requires that if you make a derivative work of Drupal and distribute it to someone else, you must provide that person with the source code under the terms of the GPL so that they may modify and redistribute it under the terms of the GPL as well…

2

My work

• … However, you are under no

obligation to distribute the code to

anyone else. If you do not distribute

the code but use it only within your

organization, then you are not required

to distribute it to anyone at all.

3

My work

• Is it permitted for me to sell

Drupal or a Drupal module or a

Drupal theme?

• Yes. However, you must distribute it

under the GPL version 2 or later, so

those you sell it to must be allowed

to modify and redistribute it as well.

Contracts

• Educate the client: let him know about

the GPL license and code ownership

Contracts

• Educate the client: let him know about

the GPL license and code ownership

• Specially if we want to release code

programmed for him…

4. Release encripted code :-) 2

Protect our code

• Release encripted code until the

project is finished.

• Then release the source code.

• That is the ONLY way to protect our

work and eventually be paid… or get

honest clients.
