New requirements for user signatures/ja

利用者の署名を取り入れるウィキは多く、それぞれ固有の要件を設けています. 編集機能チームでは署名要件をコード化してウィキペディアのソフトウェアに埋め込むという案につき、 皆さんからのご意見ご感想を募集中です. この措置が実現すると、トークページで特定のコメントへの返信することが楽になり、また他のツールの利便性も高まります.

提案の詳細とその理由は下記でご紹介します：


 * 皆さんからお聞きしたいこと： 投稿：ご意見ご感想
 * この改訂の提案理由： 背景情報：なぜこれを変更？
 * 提案された改訂点： 提案：署名確認の要件
 * 皆さんへの影響： 効果：改訂の影響

この改訂は特段の障害がない限り、2020年4月にも実施される可能性があります. 皆さんからのご意見に従って特段の修正が必要な場合、実装時期が延びる可能性があります.

投稿：ご意見ご感想
皆さんからこのプロジェクトにぜひご意見ご感想をお聞かせください.

次の質問の回答とコメントの投稿先は、トークページです：


 * 1) もし署名確認要件が導入されると、皆さんのウィキでどのような不都合がありますか？
 * 2) この改訂実施に先立ち、チームが知っておくべきことはありますか？
 * 3) 現在の署名が、改訂案の要件に見合わない場合、どんな対策をすればよいですか？ たとえば使用禁止にしますか？

上記の質問は議論の糸口であり、ほかの話題も受け付けています. 皆さんがこれは発言しておきたいという内容を、ぜひお聞かせください.

背景情報：なぜこれを変更？
ウィキメディアのプロジェクト群ならびに利用者グループのボランティア参加者20名とウィキメディア財団職員は2019年、トークページの協議に参加ました. これはオンウィキのコミュニケーションにもっと適したツールとは何にか、定義する努力の一環です.

この協議から得た成果のひとつが、トークページで特定のコメントに対してもっと楽に返信したいという声でした.

この機能がきちんと作動するにはソフトウェアが処理できる「機械可読」な署名を要件として、それを使って利用者の特定のコメント検出の信頼性を高め、返信へとつなぐ必要があります.

障害は、すでに多くのウィキで署名要件を取り入れているものの、ソフトウェア本体にその要件を組み込んでいない点です. そのため、もしウィキの慣例を破る署名が使われた場合、可能性としてですが、ほかの人が協議に参加する妨害がされるという事態が増えるかもしれないのです.

署名の書式の統一性を高めることは既存の機能の改善にもつながり、たとえば「言及」の通知は編集箇所の署名を検出できた場合にのみ、送信されるものだからです.

提案：署名確認の要件
The three proposed checks are described in this section. These would be applied to user signatures in Preferences when a user saves a modified signature. Under the Editing team's proposal, existing signatures will *NOT* be affected.

無効な HTML およびその他の Linter エラーを許可しない
Most importantly, this change would disallow unclosed formatting tags, like or the corresponding wikitext markup, , without a matching closing tag (in this case,  or  , respectively). Signatures containing invalid markup can affect the entire discussion page, when the formatting continues into subsequent comments.

The check would also identify misnested tags, like  (either both of the , or both of the  , tags should be on the outside), and stripped tags, which are closing tags without a corresponding opening tag (the opposite of the "unclosed formatting tag" listed above).

Signatures that contain some less critical problems would also be disallowed, e.g., obsolete HTML tags like  and . While these do not cause immediate issues, doing this would prevent the spread of obsolete code to new wiki pages, which is an annoyance for editors cleaning up Linter errors.

A full list of syntax features that would not be allowed, along with links to pages that explain how to update or fix code with Linter errors, is available at Help:Extension:Linter#Documentation of lint issues.

Unclosed formatting tags were already supposed to be prevented by the software, but due to limitations of the current wikitext parser, this worked only in some cases. A more robust solution has become possible thanks to Parsoid.

利用者ページ、トークページもしくは編集履歴のリンクを必須とする
Various tools don't work correctly when a signature does not contain at least one of the following links: a link to the user's user page, user talk page, or contributions page. For example, "mention" notifications are not sent, and forthcoming DiscussionTools will not allow replying to comments with these invalid signatures. Gadgets and other tools that interact with signatures also may not work as expected.

This requirement has been present for a long time in many Wikimedia wikis' policies, but it has not been enforced by the MediaWiki software.

署名に「入れ子の」代用の使用を許可しない
Some use of subst: markup and tildes would also be disallowed in signatures. Previously, it was possible to use these features to set a signature that would cause a subsequent editor's name to be placed on your comments. All forms of signature forgery have long been banned by policy at the larger wikis, and this type of forgery will now be prevented in software. Simple subst: markup is still allowed.

既存の署名はどうなりますか？
Any existing signatures that would become invalid under the new rules are still allowed (grandfathered in). When viewing your preferences, you would see a warning message about this, and if you try to change the signature, the new one must be valid. But if you don't change it, the old invalid signature will continue to be used when you sign, and you'll be able to change your other preferences without affecting it.

We're looking for feedback as to whether you would like existing invalid signatures to be disallowed. If invalid signatures are disallowed, the default signature would be inserted when affected users sign their comments, until they correct their personalized signatures.

When might these changes take place?
Please comment before 31 March 2020. The Editing team will make decisions about this project in early April. The results will be posted on the talk page.

If no obstacles are identified, this change would happen no earlier than April 2020. This date could be pushed back if the team needs to implement significant changes as a result of your feedback.

How will we know what changes are happening?
We'll include another notice in Tech/News when this change is about to be deployed.

What might the signature validation errors look like?
The HTML/lint errors include links to existing documentation about lint errors, such as Help:Extension:Linter/missing-end-tag, and a button to highlight the problematic part of the signature.

The required link errors include example wikitext syntax to use.
