Datatypes

The `sriString` Datatype

Verifiable Credentials Data Model v2.0 セクション B.3.1 の定義に準拠してください (MUST)。使用可能なハッシュについてはハッシュアルゴリズムに準拠してください (MUST)。

例1:

sha256-GtNUUolQVlwIkQU9JknWkwkhfdiVmHr/BOnLFFHC5jI=

例2:

sha256-I4OoejARWbxpTQ1HEccoxIaOIMUjEIgxEfJXJDAjwoI=
sha384-dN4FeVmV5DQb/C8iAY+sBUjLjFfB+knXZJ3RT2GyJg8Tco4SPQYwxNpe2M50b9ON

The `image` Datatype

image データ型の値は、 JSON-LD Node Object であり、次のプロパティを含みます。

id: REQUIRED. 画像の URL です。
digestSRI: RECOMMENDED. 画像の完全性を保証するためのハッシュ値です。 sriString データ型でなければなりません (MUST)。

例:

{
  "id": "https://example.com/image.png",
  "digestSRI": "sha256-OYP9B9EPFBi1vs0dUqOhSbHmtP+ZSTsUv2/OjSzWK0w="
}

`image` Datatype の検証

検証者は次の手順に従って image データ型のプロパティを検証できます (OPTIONAL)。

id プロパティの URL に GET リクエストを送り画像を取得します。
1. で取得した画像と digestSRI プロパティを SRI セクション 3.3.5 に規定されている方法で検証します。

The `page` Datatype

page データ型の値は、 JSON-LD Node Object であり、次のプロパティを含みます。

id: REQUIRED. Web ページの URL です。
name: REQUIRED. Web ページのタイトルです。

The `dateTimeStamp` Datatype

dateTimeStamp データ型の値は、 W3C XML Schema Definition Language (XSD) 1.1 Part 2: Datatypes セクション 3.3.7 dateTime の dateTimeStamp 文字列でなければなりません (MUST)。 JSON-LD Context では http://www.w3.org/2001/XMLSchema#dateTime データ型に対応します。

The `description` Datatype

https://schema.org/description データ型のサブセットです。文字列または次のプロパティを含む JSON-LD Node Object です。

text: REQUIRED. テキストコンテンツ (文字列)。
encodingFormat: REQUIRED. テキストコンテンツの符号化形式。MIME タイプでなければなりません (MUST)。

JSON-LD Node Object の例:

{
  "text": "<!doctype html><title>Example</title><h1>Headline</h1>",
  "encodingFormat": "text/html"
}

セキュリティの考慮事項

アプリケーション実装者は、text/plain 形式以外のテキストコンテンツについて、次の点に考慮してください。

テキストコンテンツの別の形式への符号化（例えば、text/markdown 形式から text/html 形式への変換など）を前提とすることは、変換処理のXSS脆弱性へのリスクから避けるべきです。
text/html 形式のテキストコンテンツを表示に使用する場合は、次のような対策を講じるべきです。
- 外部リソース読み込みの禁止、または許可リストによる制限
- CSP 制限を設けた sandbox iframe での描画
- スタイルシート読み込みの禁止、または許可リストによる制限
description データ型の配列が取得できる場合は、よりセキュリティリスクの少ない形式（text/plain 形式など）のテキストコンテンツを優先して参照することを検討してください。
