MediaWiki.org でのライセンス
MediaWiki.org 上のテキスト コンテンツはすべて、2 種類のライセンスのいずれかのもとで公開されています.


 * パブリック ドメイン ヘルプ ページは、名前の通り、パブリック・ドメイン (PD) で公開されています.
 * All other pages are released under the Creative Commons Attribution-Share Alike 3.0 Unported license (CC BY-SA).

Both licenses allow anyone to re-use the content in any way they choose. This includes charging money for access to the content, distributing it wherever and however they like, and modifying it in any way they see fit. この 2 種類のライセンスの主な違いは以下の通りです:


 * CC BY-SA のコンテンツを変更した場合、その変更もまた CC BY-SA のもとで公開しなければなりません.
 * CC-BY-SA コンテンツを利用する場合は必ず、その作者のクレジット情報を提供しなければなりません.

''This is a very basic comparison to highlight the main points. There are other differences that have not been mentioned here. Please seek proper legal advice if you are in any doubt about what you are and are not allowed to do with material released under either license.''

Image-specific permissions are located on the images' description pages.

How to spot the license
The public domain help pages are all contained within the "help" namespace. This means that their page titles will all begin Help: (for example ). They have also been given a thick blue border to make them stand out (as you can see if you follow the above link).

PD の貢献者への考慮
If you are going to contribute to the PD help pages, please ensure that all contributions come from public domain sources. This means that either you have written it yourself, or you have copied it from another source that is clearly and unambiguously released into the public domain.

Most importantly, do not contribute content released under the CC BY-SA or GFDL or any other "open" license. It may appear that this is acceptable, because there is a certain amount of similarity between the licenses, but PD is not compatible with any other license in the way that the content with any other license can't be relicensed into PD (except that you are the author of the content). However, PD content can always be relicensed into any license.

In particular:


 * Do not copy or transfer content from meta.wikimedia.org, Wikipedia or any other Wikimedia projects into the Help: namespace as they are all released under the CC BY-SA. You may of course copy it to other places on MediaWiki.org, however.
 * Within the site, do not move pages from any other namespaces into the Help: namespace.

The exception to the above rules is if you are the sole author of content for a page, in which case you may relicense your own material by posting it to the Help: namespace as public domain. Note that this is a one way process - you cannot change your mind once it has been done!
