Like LinkedIn, Netflix, Lyft, Shopify and others, Uber developed a metadata management platform, Databook, to help team members find and evaluate data artifacts (e.g. datasets, dashboards, metrics). However, as the company expanded into new markets and with new products, Databook did not scale. Users needed additional context, including lineage information and data quality profiles. Consequently, Uber redesigned and rearchitected Databook, including by: defining a Data Standardization process that improved the consistency and reusability of metadata types; implementing a more flexible and extensible data model that represents metadata as a set of properties and relationships; standardizing metadata ingestion into an event log; creating a centralized metadata store; building an easy-to-use, React-based UI.
