The document discusses implementing data contracts and governance for Looker Studio assets like data sources, blends, segments and filters. It notes that as a Looker Studio footprint grows organically, it can become chaotic without proper ownership, auditability, governance and consistency. The document proposes creating self-documenting assets with human and machine-readable data contracts that describe data sources, dimensions, metrics and other details. It provides templates for summary and data source contracts that can be populated from sheets. The goal is to apply structure, rigor and governance to data visualization through recording assets in a library, auditing creation and access, and managing maintenance.
