Context chromium-dev is the official Chromium developers mailing list. Content This dataset was created by crawling Google Groups using [ggmbox](https://github.com/vmarkovtsev/ggmbox). It is possible to fetch raw emails given their ID, so first all the topics were discovered and listed and then individual emails fetched. This dataset has **15379 topics** with **78975 messages**. `chromium-dev.tar.xz` is the fetched emails as of 2018/12/09 and `chromium-dev.json.gz` is the metadata of each discussion topic. There is also `threads.csv.gz` with plain text messages per topic, in logical order and with some filtering performed. E.g. citations were removed. If you want to improve it or write a custom information extractor, refer to [parse.go](https://github.com/vmarkovtsev/ggmbox/blob/master/parse.go). Python users: emails can be loaded with [`email.message_from_file()`](https://docs.python.org/3/library/email.parser.html#email.message_from_file) but some additional work may be required to decode base64-encoded parts of some files, see [MIME](https://en.wikipedia.org/wiki/MIME).
