Axiome Semantic Layer
What Axiome Semantic Layer is
Axiome Semantic Layer provides a governed foundation for charts, tables, and AI answers, so they can use consistent business definitions. Connect a database and the service inspects its schema, then creates a model for each table with dimensions and measures. Administrators can rename or describe fields, hide internal columns, and set official metrics such as revenue or conversion rate. Models can also define keys and joins, and can be returned to their generated baseline.
When a source schema changes, Axiome reports new, removed, or modified elements, preserves customizations, and flags orphaned dimensions. Its connections page names native BigQuery and PostgreSQL connectors, with additional sources in development. Axiome says it reads data on demand through a read-only account and neither migrates nor copies it. Connection credentials are kept in Google Cloud Secret Manager, retrieved server-side, and not sent to the browser. The cloud service describes its hosting as European and says it is GDPR-compliant. Its AI analyst, Axi, responds to plain-language questions and creates or edits dashboard charts using the governed definitions. Axiome SAS is based in Paris, and the company says its story began in 2024.
