“…-Folder structure: from the perspective of file naming, code organisation and storage, this is the tree structure composed of elementary components (source files, source folders). The root of the tree is represented by the parent folder [9,8]. -Extensibility of a source folder: following Martin [24] who defines extensibility as the number of concrete and abstract classes in a package, we define the number of source files contained in a folder as the extensibility of that folder.…”

Abstract. Open Source Software (OSS) communitieshave not yet taken full advantage of reuse mechanisms. Typically many OSS projects which share the same application domain and topic, duplicate effort and code, without fully leveraging the vast amounts of available code. This study proposes the empirical evaluation of source code folders of OSS projects in order to determine their actual internal reuse and their potential as shareable, fine-grained and externally reusable software components by future projects. This paper empirically analyses four OSS systems, identifies which components (in the form of folders) are currently being reused internally and studies their coupling characteristics. Stable components (i.e., those which act as service providers rather than service consumers) are shown to be more likely to be reusable. As a means of supporting replication of these successful instances of OSS reuse, source folders with similar patterns are extracted from the studied systems, and identified as externally reusable components. The intended users are members of the OSS development community. Based on the empirical study of the OSS systems and observations made during the study, four practical courses of action are recommended in order to enhance the reusability of current folders that have not been identified as potentially reusable, both from an internal and external standpoint.
