Comparing the universal variability language with other textual variability modeling languages

We compare the main features of the recently introduced Universal Variability Language (UVL) with other textual variability modeling languages from the software product line engineering domain. This comparison is structured according to the level of support that each language provides according to five dimensions: configurable elements, constraints, configuration, scalability, and formal semantics. This work extends our earlier work on comparing textual variability modeling languages that used a similar approach (Eichelberger and Schmid, 2015; ter Beek, Schmid, and Eichelberger, 2019).
