A collection of all publicly available mail archives from the Apache55 Software Foundation (ASF), taken on July 11, 2011. This collection contains all publicly available email archives from the ASF's 80+ projects (http://mail-archives.apache.org/mod_mbox/), including mailing lists such as Apache HTTPD Server, Apache Tomcat, Apache Lucene and Solr, Apache Hadoop and many more. Generally speaking, most projects have at least three lists: user, dev and commits, but some have more, some have less. The user lists are where users of the software ask questions on usage, while the dev list usually contains discussions on the development of the project (code, releases, etc.) The commit lists usually consists of automated notifications sent by the various ASF version control tools, like Subversion or CVS, and contain information about changes made to the project's source code.
Both tarballs and per project sets are available in the snapshot. The tarballs are organized according to project name. Thus, a-d.tar.gz contains all ASF projects that begin with the letters a, b, c or d, such as abdera.apache.org. Files within the project are usually gzipped mbox files.
