SIMICA系列标准为信息系统提供了独立于实现的软件接口，其中包含与复杂系统（由硬件、软件或其任何组合组成）的诊断和维护相关的数据。本标准定义了EXPRESS信息模型和XML模式，它们共同定义了支持这些接口的公共信息元素。

The SIMICA family of standards provides an implementation-independent software interfaces to information systems containing data pertinent to the diagnosis and maintenance of complex systems consisting of hardware, software, or any combination thereof. This standard defines EXPRESS information models and XML schemas that together define the common information elements supporting these interfaces.
