  We present GHTraffic, a dataset of significant size comprising HTTP
transactions extracted from GitHub data and augmented with synthetic
transaction data. The dataset facilitates reproducible research on many aspects
of service-oriented computing. This paper discusses use cases for such a
dataset and extracts a set of requirements from these use cases. We then
discuss the design of GHTraffic, and the methods and tool used to construct it.
We conclude our contribution with some selective metrics that characterise
GHTraffic.
