The Software Package Data eXchange(SPDX) specification is a standard format for communicating the software components, licenses and copyrights. It is hosted at the Linux Foundation whose goal is to facilitate compliance with free/open source software licenses and the exchange of such information between companies. As a company that uses free/open source software in various products, we started using SPDX in a pilot mode and applied the specification to our open source governance system. In this talk, we will discuss at length two cases of the use of SPDX in practice based on our experience. The first case study is focused on reducing the cost of verifying open source licenses(auto-identify component), and the second case study is focused on the implementation of the license note web system. Furthermore, the talk will provide a few suggestions to improve the spec based on our experiences.
