Abstract: In almost every empirical software engineering study, software metrics collection is a fundamental activity. Although many tools
exist to collect this data, it still takes a considerable amount of time. In addition, almost all researchers collect essentially the same
data (e.g., CK metrics, McCabe Cyclomatic Complexity, etc.) from essentially the same sources (e.g., well-known open-source
projects).Having so much duplication of work done within a community reduces the amount of time that researchers can spend
developing new ideas and evaluating them empirically, which is the most valuable part of their research. In this paper, we propose a
novel approach for getting and sharing software metrics data that will allow them to collaborate and reduce the amount of wasted
effort. SMEF, a file format for exchanging software metrics information, and a REST API, targeted at this objective, are proposed in this paper.
Index terms: new exchange format, software metrics.
