One of the challenges in open source license compliance is just identifying which licenses are present in the source code. SPDX has created a set of matching guidelines and a license template syntax to help tools match text against the SPDX license list. Kris Reeves will share his practical experience using the SPDX license list for identifying licenses in node.js and how it has led to improvements both in the SPDX license list and making the SPDX license list more accessible for contributors. We will discuss how you can review and make contributions to the SPDX license matching syntax. We will also discuss how you can use the SPDX license list in your own software tools using some of the new formats available on spdx.org/licenses.
