Most dependency managers integrate a licensing dimension to their packages and their contributors are generally very receptive to best practices in the domain, like following the SPDX standard and its evolutions. The importance of the legal dimension of these tools is underlined by the evolution of the services that are built on top of them: services like versioneye and librairies.io had their primary focus on technical aspects (like detecting not up to date dependencies), but now also includes features related to licensing like licence whitelisting or licence compatibility. This short talk will present a summary of the maturity of the different package managers licencing-wise, some examples of concrete issues of implementing best practices, and tools that already exist or that are still lacking to allow developpers to take advantage of easily-available licensing information.
