[Purpose/significance] The scientific experimental data lacks of suitable and effective organization and loses easily and frequently, which seriously hinders preserving, reusing and publicly accessing the scientific data. So to build the normative scientific experimental data metadata model is of great significance to organize, preserve, retrieval and reuse experimental data.[Method/process] Firstly, this paper summarizes the existing scientific experimental metadata models by literature investigation. Secondly, it establishes a metadata description scheme of botany gene expression experiment, by investigating and summarizing organization condition of experimental data, operating process and characteristic of experiment through expert interviews. Lastly, it scores, evaluates, selects and determines the metadata factors by Delphi method.[Result/conclusion] This paper builds a metadata model for botany gene expression experiment based on scientific experimental data lifecycle. The model can completely describe the basic information such as experiment design and data, and other information such as scientific achievements and data access. The metadata model not only can help organize the scientific experimental data, but also publicly access experimental data and review achievements, to provide support for semantic association of different types of scientific data.
