Hi, all.

Our group is working on how to identify configuration types of software. In this context, a configuration type refers to a Java type (class, interface, or enumeration type) that is used to manage configuration options or configuration methods. To investigate the characteristics of the configuration types, we manually identified the configuration types of LibRec (V3.0.0, bb5efc4 on 14 Oct 2020). The results are shown below.

• net.librec.conf.Configuration: manages configuration methods
• net.librec.conf.Configured: manages configuration options
• net.librec.tool.driver.DataDriver: manages configuration options for command line
• net.librec.tool.driver.RecDriver: manages configuration options for command line

In order to increase the reliability of the research results, could you please help us to confirm the results? Thank you for your time and cooperation!
