dependent from the specific type of traced artifacts.
Further, it is well integrated into an established work-
bench and development environment using Xtext and
the Eclipse Modeling Framework. Features such as
live validation and error markers detect broken or out-
dated expressions early and ensure a rich user experi-
ence.
The focus of future work should be on identi-
fying new industry-relevant metrics by applying the
proposed approach to real-world projects. Also, the
data mining field offers statistical methods through
association rules or regression algorithms to find pat-
terns and gain insights from large data sources such
as traceability models.
To sum up, the analysis language proposed in
this paper offers an integrated approach to close the
gap between querying traceability information mod-
els and defining configurable metric expressions. The
concept of ad hoc evaluation of expressions was
demonstrated in a prototypical implementation.
