          <datacite:description descriptionType="Other">今後  あらゆる場所で機器やサービスが利用できるユビキタスコンピューティング環境が整備されていくに従い  従来のように個人または組織が機器やサービスを所有するという概念に代わり  機器やサービスを利用する権利  すなわち利用権が必要に応じて動的に付与されるという概念が定着すると予想される. 我々は上記のようなユビキタス環境実現に向けたアーキテクチャModel-based Ubiquitous Service Architectureを提案している. 本稿ではMUSAにおける利用権条件記述方式について既存の標準アクセス制御記述言語であるXACML (eXtensibleAccess Control Markup Language)とこれを基本とした条件判定モデルの適用時の問題点を明らかにし  利用権管理に向けた最適なモデルについて提案する.</datacite:description>
          <datacite:description descriptionType="Other">As ubiquitous computing technology (ex. services and resources can use everywhere) increasingly becomes a part of our daily life, we predict a change uses of services and resources from possession to utilization on demand. In this paper we present MUSA, a Model-based Ubiquitous Service Architecture system for managing and circulating permission to use. MUSA operates by dynamic decisioning and collecting permission to use information. We present results of verification that demonstrate the ability of MUSA's decision model to manage permission to use with eXtensible Access Control Markup Language (XACML)</datacite:description>
