A Project is a backend context graph - the semantic structure of your data. It defines what entities exist, how they relate, and how they map to your Sources. A Project contains:
  • Entities: Semantic concepts like “Customer,” “Order,” or “Product”
  • Relationships: How entities connect, like “Customer places Order”
  • Mappings: Connections between semantic entities and Source data (e.g., mapping “Customer” to specific tables and columns)
Projects attach to one or more Sources. The Source provides factual structure. The Project provides semantic meaning.

Creating a Project

How to create your first project. Start by creating a new project from Projects.
  1. Select Sources: Choose which Sources to attach to your Project
  2. Choose mapping method:
    • Auto-introspect: Galaxy analyzes your Sources and automatically generates initial models
    • JSON: Define your context graph structure using JSON
    • Blank: Build from scratch with a canvas experience
  3. Run context graph pipeline: Galaxy processes your Sources and generates the initial semantic graph
Projects can span multiple Sources, allowing you to build unified semantic understanding across your entire data ecosystem.
