The RDF Mapping Language (RML) enables, among other formats, the mapping of tabular data as Comma-Separated Values (CSV) files to RDF graphs. Unfortunately, the widely used spreadsheet format is currently neglected by its specification and well-known implementations. Therefore, we extended one of the tools which is RML Mapper to support Microsoft Excel spreadsheet files and demonstrate its capabilities in an interactive online demo. Our approach allows to access various meta data of spreadsheet cells in typical RML maps. Some experimental features for more specific use cases are also provided. The implementation code is publicly available in a GitHub fork.

将电子表格映射到RDF：在RML中支持Excel

除了其他格式外，RDF映射语言（RML）支持将表格数据作为逗号分隔值（CSV）文件映射到RDF图。不幸的是，目前广泛使用的电子表格格式已被其规范和众所周知的实现所忽略。因此，我们扩展了一种工具RML Mapper，以支持Microsoft Excel电子表格文件并在交互式在线演示中演示其功能。我们的方法允许访问典型RML映射中电子表格单元格的各种元数据。还提供了一些针对更具体用例的实验功能。实施代码可在GitHub分支中公开获得。
