From OpenGL Wiki

Platform specifics: Linux changes

You've made a number of changes to this page yesterday, and it's good to see more interest in the OpenGL Wiki. However, a problem came to light when I looked at the various text and links you added. I came to realize that a lot of the text (including some added months ago) is copied directly from other sites. That's very likely a violation of those sites' copyrights, even though you attributed it by linking to it.

Adding copy-written text to this wiki from other sites is not a good idea. All of the copied text must be rewritten. Otherwise, I'm afraid I will have to revert the page to the 2012 version.

This also makes me concerned about the source of that image you uploaded. Is that copy-written as well? If so, it will have to be removed and/or replaced by an image you can donate. Or, at the very least, put a link to where it was found on the image page, so that their reuse policy can be examined.

On a lesser note, the styling of the text violates a lot of Wikipedia's manual of style. Particularly around your rather liberal use of line breaks. When you go back and fix the above problems, you should repair these as well. Alfonse (talk) 10:20, 12 September 2015 (EDT)

Hi Alfonse!
"Adding copy-written text to this wiki from other sites is not a good idea. All of the copied text must be rewritten."
The main idea was to reorganize the structure of the article and to provide focal points for the reader. Also one of the major goals was, to minimize the amount of text. In this case, - nothing could be better then the original quotes instead of reinventing the weel. Rewritten text of the main ideas of the original autors could change the meaning in unacceptable way, but i should try to do my best against that on the next revision of this article.
"This also makes me concerned about the source of that image you uploaded. Is that copy-written as well? If so, it will have to be removed and/or replaced by an image you can donate."
This image was exported personally by me from the kcachegrind while i profile the simple gl es application. So it's my ownership which i provide for gl wiki without any limits let it be under i.e. MIT licence.

Ok, i should pay more attention to the quality of style. Alexcham

Whether it's reinventing the wheel or not, copyrights have to be respected. Just because it's on the web doesn't mean it isn't owned. You could get the Wiki in trouble by posting direct copies from a copy-written source.
Also, while minimizing text is an important goal, putting useful information on the page itself is a more useful goal. Like Wikipedia, farm we're not a link farm. Linking to external sites that provide greater depth of information is good, but this Wiki shouldn't just be a summary text followed by links to the actual information. If you're going to have a section explaining how the Linux DRI works, then explain it. Alfonse (talk) 12:39, 13 September 2015 (EDT)
