[目的/意义] 开放政府数据有利于实现数据资源的合理开发和利用，鼓励社会创新，促进经济发展。保障开放政府数据的有效利用、社会化增值离不开高质量的元数据方案的支持。[方法/过程] 通过研究分析国内外开放政府数据的相关研究成果，对我国主要的地方政府开放数据平台的元数据方案进行调研，并与美国政府开放政府数据元数据标准进行比较分析。[结果/结论] 结果表明，我国地方政府开放数据存在着元数据方案各不相同，对数据集的描述简单、不全面，格式以HTML网页为主，机器可读性不高等不足，影响开放数据的使用效果。因此，我国政府应借鉴国际上成熟有效的元数据方案标准，制定统一规范的元数据方案，确保提供满足社会需求的高质量、高价值数据。

[Purpose/significance] Open government data is conducive to the rational development and utilization of data resources. It can encourage social innovation and promote economic development. Besides, in order to ensure effective utilization and social increment of open government data, high-quality metadata schemes is necessary. [Method/process] Firstly, this paper analyzed the related research of open government data at home and abroad. Then, it investigated the open metadata schemes of some Chinese main local governments’ data platforms, and made a comparison with the metadata standard of American open government data. [Result/conclusion] This paper reveals that there are some disadvantages about Chinese local government open data affect the use effect of open data, which including that different governments use different data metadata schemes, the description of data set is too simple for further utilization and usually presented in HTML Web page format with lower machine-readable. Therefore, our government should come up with a standardized metadata schemes by drawing on the international mature and effective metadata standard, to ensure the social needs of high quality and high value data.
