  In the last decades, data have become a cornerstone component in many
business decisions, and copious resources are being poured into production and
acquisition of the high-quality data. This emerging market possesses unique
features, and thus came under the spotlight for the stakeholders and
researchers alike. In this work, we aspire to provide the community with a set
of tools for making business decisions, as well as analysis of markets behaving
according to certain rules. We supply, to the best of our knowledge, the first
open source simulation platform, termed Open SOUrce Market Simulator (OSOUM) to
analyze trading markets and specifically data markets. We also describe and
implement a specific data market model, consisting of two types of agents:
sellers who own various datasets available for acquisition, and buyers
searching for relevant and beneficial datasets for purchase. The current
simulation treats data as an infinite supply product. Yet, other market
settings may be easily implemented using OSOUM. Although commercial frameworks,
intended for handling data markets, already exist, we provide a free and
extensive end-to-end research tool for simulating possible behavior for both
buyers and sellers participating in (data) markets.
