本文件规定了由信息系统的特定体系结构层（即服务体系结构）实施的信息模型的基本特征，以提供通用企业数据的全面集成存储，并支持ISO 12967？1中定义的医疗保健组织的基本业务流程。 本文件中规定了信息模型，但没有对各种目标场景中物理实现所采用的物理技术、工具或解决方案做出任何明确或隐含的假设。然而，该规范是正式的、完整的、不含糊的，足以允许实施者在特定的技术环境中得出系统的有效设计，该技术环境将被选择用于物理实施。 本文件的目的并不是代表任何医疗保健企业的任何要求所需的所有可能数据的固定、完整的规范。它仅就整体组织和单个信息对象指定了一组特征，这些特征被确定为所有医疗保健组织的基本特征和通用特征，并且由服务体系结构实现的信息模型满足了这些特征。 为了保持与本文件规定的一致性，允许对标准信息模型进行物理实现扩展，以支持附加和本地需求。扩展包括在标准模型的对象中定义附加属性，以及实现全新的对象。 此外，根据适用标准化计划的发展，本文件规范可随时间扩展。 扩展规范按照ISO 12967-1:2020第7条中定义的方法进行。

This document specifies the fundamental characteristics of the information model implemented by a specific architectural layer (i.e. the service architecture) of the information system to provide a comprehensive and integrated storage of the common enterprise data and to support the fundamental business processes of the healthcare organization, as defined in ISO 12967？1. The information model is specified in this document without any explicit or implicit assumption on the physical technologies, tools or solutions to adopt for its physical implementation in the various target scenarios. The specification is nevertheless formal, complete and non-ambiguous enough to allow implementers to derive an efficient design of the system in the specific technological environment that will be selected for the physical implementation. This document does not aim at representing a fixed, complete, specification of all possible data that can be necessary for any requirement of any healthcare enterprise. It specifies only a set of characteristics, in terms of overall organization and individual information objects, identified as fundamental and common to all healthcare organizations, and that is satisfied by the information model implemented by the service architecture. Preserving consistency with the provisions of this document, physical implementations are allowed extensions to the standard information model in order to support additional and local requirements. Extensions include both the definition of additional attributes in the objects of the standard model, and the implementation of entirely new objects. Also, this document specification is extensible over time according to the evolution of the applicable standardization initiatives. The specification of extensions is carried out according to the methodology defined in ISO 12967-1:2020, Clause 7.
