URIのスキーム一覧

tag URIをもっとあちこちで使いたい。例えばXML名前空間名には、httpよりもtagの方が適切に思える。しかし、RFCのステータスがINFORMATIONALなのが気になった。使う上でどのくらい問題なんだろう。

とりあえず全スキームのRFCステータスを調べてみた。IANAの一覧を使って生成。

• IANA | URI Schemes
• http://www.ietf.org/download/rfc-index.txt

生成に使ったスクリプト。

• http://gist.github.com/426852

RFCのステータスについては、以下の記事がわかりやすかった。

• RFC 822 と RFC 2822 - あどけない話
• Internet StandardsとRFC − ＠IT
• RFCの分類
• JPNIC RFC-JP(IETFにおける標準化プロセス)

スキームの登録方法はRFC4395で定められている。

• RFC 4395 - Guidelines and Registration Procedures for New URI Schemes
• 過剰なURIスキームは有害である
• New Uniform Resource Identifer Schemes Considered 99% Harmful
  • 独自のスキームが欲しくなったら urn, tag, esl を検討せよという記述が。
  • esl? http://tools.ietf.org/html/draft-palmer-esl-uri-00
