We present recent results from the xFitter project--an open-source
software framework for the determination of PDFs and the analysis of
QCD physics. xFitter has been used for a variety of LHC studies
including the measurement of the strange PDF, which we briefly
summarize. Additionally, charged current DIS charm production
provides a complementary perspective on s(x). We make use of the
xFitter tools to study the present s(x) constraints, and then use LHeC
pseudo-data to infer how these might improve. Furthermore, as xFitter
implements both Fixed Flavor and Variable Flavor number schemes, we
can examine the impact of these different theoretical choices. This
study provides a practical illustration of the many features of xFitter.
