模板

模板（template）是指一套针对HL7 V3 RIM的约束的表达形式；其中，这些约束用于对相应类别数据的实例的特定部分施加额外的限制，而相应数据类别则是利用其他某种静态模型（Static Model）来表达的。模板旨在采用更为局限和焦点更为集中的适用范围，对已有的模型进一步加以定义和细化。模板的表达形式为静态模型，并且还可以采用某种便于计算机处理的形式来表达附加约束。此外，每个模板还关联有一套元数据，用于描述模板的目的和用途。

定义原文：a template is an expression of a set of constraints on the RIM which is used to apply additional constraints to a portion of an instance of data which is expressed in terms of some other Static Model. Templates are used to further define and refine these existing models within a narrower and more focused scope. A template is represented as a Static Model, optionally with additional constraints expressed in some computable form. In addition, there is a set of metadata associated with every template to describe the purpose and use of the template.
