ShortcutCOM:CREDIT

Credit line(クレジットライン) もしくは attribution line(著作権の表示欄)は、ライセンスが求める使用条件として、作品を利用する人すべてに作品に添えるよう作品の著者が求める情報を保持しています。具体的に言うと、広く用いられているCreative Commons CC-BYライセンスとGFDL ライセンスは、作品を使用する人すべてに著者を表示するよう求めています。

ここでは "credit line" という言葉を使っていますが、求められる属性表示は、"credit line" として指定する必要はなく、属性の形式も指定されていません。 Although the term "credit line" is used here, the required attribution need not be specified as a credit line, neither is the format of the attribution specified.

ある作品においては、その作品の著作権をどのように表示するのかについて、作者から特定の指示があるかもしれません。そうした指示は、それがライセンスで認められる範囲内である限り、尊重されなければなりません。もしそうでなくても、妥当であれば、尊重した方が良いでしょう。作者が明確な指示を与えていない場合には、作者の名前および以下に説明するような最小限度の形式による著作権の表示をしなければなりません。

CC-BY と CC-BY-SA のライセンス 

According to Creative Commons CC BY and CC BY-SA licenses, reusers must attribute the work by providing a credit line. Section 4b (Section 4c in CC BY-SA 3.0) of full license provides the details. Included below are the most relevant fragments:

If You Distribute [] the Work or any Adaptations or Collections, You must, unless a request has been made [not to], keep intact all copyright notices for the Work and provide, reasonable to the medium or means You are utilizing:

  • (i) the name of the Original Author (or pseudonym, if applicable) if supplied, and/or if the Original Author and/or Licensor designate another party or parties (e.g., a sponsor institute, publishing entity, journal) for attribution ("Attribution Parties") in Licensor's copyright notice, terms of service or by other reasonable means, the name of such party or parties;
  • (ii) the title of the Work if supplied;
  • (iii) to the extent reasonably practicable, the URI, if any, that Licensor specifies to be associated with the Work, unless such URI does not refer to the copyright notice or licensing information for the Work;

In other words, unless author or licensor asks not to be credited, reusers distributing files found at Wikimedia Commons must provide credit line with license and author. Also author might request for credit line to include: other "Attribution Parties" (like Wikimedia Commons), URI (like web pages), or title. Reusers can choose format of the credit line "reasonable to the medium or means" as long as all required components are present. Example Credit lines in minimal format:
