目标概述：不仅架构师，而且信息管理人员都需要针对其工作主题的模型和建模工具。为支持医院战略信息管理，提出了医院综合信息系统（HIS）Meta模型3LGM 2的本体论基础。方法：通过实例分析，推导出HIS系统建模的要求. 3LGM2在此基础上设计了三个层次的概念来描述HIS。领域层由企业功能和实体类型组成，逻辑工具层侧重于应用程序组件，物理工具层描述物理数据处理组件。与其他方法相比，存在许多层间关系。3LGM2使用统一建模语言（UML）定义。结果如下：可以创建的模型，它不仅包括技术和语义方面，但也基于计算机和基于纸张的信息处理。开发了一种软件工具，以图形方式支持创建符合3LGM2的模型。该工具支持在逻辑或物理工具层，使其无法满足在域层的信息需求检测这些缺点。3LGM2也可以作为一个本体，用自然语言描述HIS。结论：即使在大型医院的战略信息管理应该和可以支持专用的方法和工具。虽然有良好的经验与3LGM2有关的数字文件存档在莱比锡大学医院，这是在第2部分，所提出的方法和工具的好处，必须进一步评估。
Summary Objectives: Not only architects but also information managers need models and modeling tools for their subject of work. Especially for supporting strategic information management in hospitals, the meta model 3LGM2 is presented as an ontological basis for modeling the comprehensive information system of a hospital (HIS). Methods: In a case study, requirements for modeling HIS have been deduced. Accordingly 3LGM2 has been designed to describe HIS by concepts on three layers. The domain layer consists of enterprise functions and entity types, the logical tool layer focuses on application components and the physical tool layer describes physical data processing components. In contrast to other approaches a lot of inter-layer-relationships exist. 3LGM2 is defined using the Unified Modeling Language (UML). Results: Models of HIS can be created which comprise not only technical and semantic aspects but also computer-based and paper-based information processing. A software tool supporting the creation of 3LGM2 compliant models in a graphical way has been developed. The tool supports in detecting those shortcomings at the logical or the physical tool layers which make it impossible to satisfy the information needs at the domain layer. 3LGM2 can also be used as an ontology for describing HIS in natural language. Conclusions: Strategic information management even in large hospitals should be and can be supported by dedicated methods and tools. Although there have been good experiences with 3LGM2 concerning digital document archiving at the Leipzig University Hospital, which are presented in part 2, the benefit of the proposed method and tool has to be further evaluated.
