Archtectural Overview Design Principles
v15 v16 38 38 One of the key paradigms on which openEHR is based is known as "two-level" modelling, described in [2]. Under the two-level approach, a stable reference information model constitutes the first level of modelling, while formal definitions of clinical content in the form of archetypes and templates constitute the second. Only the first level (the Reference Model) is implemented in software, significantly reducing the dependency of deployed systems and data on variable content definitions. The only other parts of the model universe implemented in software are highly stable languages/models of representation (shown at the bottom of FIGURE 4). As a consequence, systems have the possibility of being far smaller and more maintainable than single-level systems. They are also inherently self-adapting, since they are built to consume archetypes and templates as they are developed into the future. 39 39 40 アーキタイプとテンプレートはまた、用語体系や分類、コンピュータ化された臨床ガイドラインに対してセマンティクスを与えるものである。 40 アーキタイプとテンプレートはまた、用語体系や分類、コンピュータ化された臨床ガイドラインに対してセマンティクスを与えるものである。過去には他の方法で、システムの機能を固有のソフトウェアと用語体系の組み合わせだけで構築しようと試みられていた。この手法には欠点がある。用語体系はドメイン内容の定義を含まず、元実世界の事実(例えば、微生物の種類とそれが人体に与える影響）をむしろ定義するものであるからである 41 41 42 42 Archetypes and templates also act as a well-defined semantic gateway to terminologies, classifications and computerised clinical guidelines. The alternative in the past has been to try to make systems function solely with a combination of hard-wired software and terminology. This approach is flawed, since terminologies don't contain definitions of domain content (e.g. "microbiology result"), but rather facts about the real world (e.g. kinds of microbes and the effects of infection in humans). 43 44 openEHRでアーキタイプを使っていくことで、[http://www.openehr.jp/attachment/wiki/Archtectural%20Overview%20Design%20Principles/design_principles3.gif 図5]のように情報とモデルの新しい関係を生み出すことができる。 43 45 44 46 The use of archetyping in openEHR engenders new relationships between information and models, as shown in FIGURE 5.
