ぶ)、たとえばXrML(商標)を使用することができる。次に、権利ラベル510、および平文コンテンツ501を暗号化するために使用された適切な暗号化キーは、ライセンス・サーバ512へ提供される。
For every condition on the conditions list
(条件リスト上の全ての条件について)

(バリデータ・リスト上の全てのバリデータについて)
Perform condition validation
(条件の確認を実行する)
If condition is valid, skip to the next by exiting the inner for−loop
(もし条件が有効であれば、内部forループを出て次へスキップする)
If condition is invalid, then skip to
the next validator
(もし条件が無効であれば、次のバリデータへスキップする)
End−for(validators list)

図7は、権利表記ライフサイクル100の権利表記変更プロセス段階120の間に権利表記を変更する他の例示的方法を示す概略図330である。具体的には、概略図330は、中へデータをマージすることを可能にするトークンを含む、トークン化された権利表記332を示す。本例では、トークン化された権利表記332の中に現れている「<cgXrML:CGTOKEN TOKENNAME=”<tokenName>”/>」と読める行は、権利の実施可能なセットが形成される前に、この行の全体が何らかの実際のデータで置換されるべきことを示す。トークン化された権利表記332の中のトークンの置換値は、置換値表記334の中で提供され、置換値表記334は、トークン化権利表記332の中のトークンと置換される。その結果、現在の例では権利の実施可能なセットである権利表記336を生じる。

上記の説明によって、本発明の1つの実施形態に従った権利表記処理システムは、文法ベースの権利表記を生成、変更、認証、および確認するために使用される新規および有利なシステムを提供することが明かであろう。説明されたように、権利表記処理システムは、拡張可能ポイントを備えた拡張可能アーキテクチャによって実現されてよく、拡張可能アーキテクチャは、権利表記の意味または文法を変更することなく、新しい構文の付加を可能にし、新しい権利表記への適応を可能にする。この拡張可能性は、インタープリタおよびバリデータのような権利表記処理システムのコンポーネントを、プラグイン・コンポーネントとして実現するのが好ましい。
