The Crossref Event Data system has a number of components. All parts of the system that are used to generate or distribute Events, Evidence, Artifacts are open source. Whilst you will probably never want to run any of this software, it may help with the interpretation of the data.
Crossref Event Data uses a collection of software. It is all open source, and you can browse it our repository on Github under the 'crossref-event-data' label.
