A system includes a database that stores attributes of applications that are descriptive of source code included in the applications and identification data that identifies the applications to which the attributes apply. The attributes are mined through a programmatic analysis of one or more repositories in which the applications are stored, and the programmatic analysis includes programmatic analysis of the source code included in the applications to derive the attributes. The system also includes a computer system configured to handle queries against the attributes of the applications stored in the database and provide output based on the handling of queries against the attributes of the applications stored in the database.
