  Schibsted Media Group is a global marketplace company with presence in more
than 20 countries. It is undergoing a digital transformation to convert data
silos to a multi-tenant system based on a common data platform. Good data
quality based on a common schema on the semantic level is essential for
building successful data-driven products across marketplaces. To solve this
challenge, we developed the data quality tooling based on a semantic schema
management system to support schema evolution with versioning, testing and
transformation. It can monitor the data quality requirements for different
applications and handle incoming data consisting of multiple schema versions.
Today the system is operating in production and processes over one billion
events per day for over 100 applications.
