What is the foundation on which all application artifacts are built?

• A. Metadata
• B. Dashboards
• C. Rules
• D. Mapping Rules

Answer: (A)

The foundational element is metadata. It defines the structure and vocabulary of the application—dimensions, accounts, hierarchies, member properties, calendars, versions, mappings, and other structural definitions. Everything built in OneStream—rules, dashboards, and mapping rules—depends on that metadata. Rules operate on the defined accounts and dimensions; dashboards display data and metrics that arise from those definitions; mapping rules apply to the mapping metadata to translate external data into the internal structure. Because all artifacts reference and rely on this metadata model, it serves as the backbone for the entire application.
