SDMetrics Core is a Java library to calculate metrics of structural design properties such as coupling, size, and complexity for UML designs. It also checks design rules to automatically detect incomplete or incorrect design, and adherence to style guidelines such as circular dependencies or naming conventions. The library provides an XMI parser for import of XMI 1.x files with UML1.3/1.4 models, and XMI 2.0/2.1 files with UML 2.x models. Design metrics, rules, and XMI import are highly customizable.
Squale (Software QUALity Enhancement) provides models and associated tools to assess software quality and help improve it over time. Its models and tools know how to aggregate raw quality information (such as metrics) given by third party technologies into high-level factors, offer dashboards which present those factors and allow digging deeply into the code quality, show the evolution of quality over time, and give economical indicators about the return on investment of quality efforts.
