IEC 61970-552:2016规定了基于CIM交换建模信息的格式和规则。它使用IEC 61970-501中提出的CIM RDF模式作为构建电力系统建模信息XML文档的元模型框架。这些文档的样式称为CIMXML格式。与上一版相比，此新版本包括以下重大技术变更: -定义CIMXML格式版本化的新子句； -增加关于强制性标题的声明； -介绍新的urn:uuid表单并讨论向后兼容性。

IEC 61970-552:2016 specifies the format and rules for exchanging modelling information based upon the CIM. It uses the CIM RDF Schema presented in IEC 61970-501 as the meta-model framework for constructing XML documents of power system modelling information. The style of these documents is called CIMXML format. This new edition includes the following significant technical changes with respect to the previous edition:
- new clause that defines the versioning of CIMXML format;
- addition of a statement about mandatory header;
- introduction of the new urn:uuid form and discussion of the backwards compatibility.
