Interoperability for Data Repositories. Metadata-based procedures for Retrieving Data for Display or Mining Utilising Persistent (data-DOI) Identifiers.

In the spirit of the Joint Declaration of Data Citation Principles, we present three flexible solutions for enabling machine-access to repository-based scientific data, given knowledge of the persistent identifier (DOI) of the dataset. Data from published chemical datasets will be retrieved by these methods for visualisation by clicking any of the buttons in the demonstrator.秉承《数据引用原则联合声明》（Joint Declaration of Data Citation Principles）的精神，当已知数据集的持久标识符（DOI，Digital Object Identifier）时，我们提出三种灵活方案，以实现基于数据仓储的科学数据的机器可访问性。借助上述方案，可检索已发表的化学数据集数据，用户点击演示工具中的任意按钮即可完成可视化展示。
