Based on the criteria proposed in On the reproducibility of empirical software engineering studies based on data retrieved from development repositories (Open Access - Empirical Software Engineering, Volume 17, Numbers 1-2, 75-89), the attributes of this study are given in following table:

Details

• Identification:
  • Apache mailing lists (http://mail-archives.apache.org/mod_mbox/)
  • Apache Mailing lists (recreation of the mboxes at people.apache.org)
• Description:
  • Apache Mailing lists (http://www.apache.org/foundation/mailinglists.html)
  • As we had access to the people.apache.org machine where the list content is stored in mbox file, we offer a replication of the structure. (TBD)
• Availability: Public.
• Persistence: Yes.

• Description: Data with the traffic on a monthly basis per project in CSV (comma-sepparated values) format.
• Availability: Public.
• Persistence: Yes.
• Flexibility: Yes.
