3## Workflow

51. **Create the file**: Create a `.base` file in the vault with valid YAML content
62. **Define scope**: Add `filters` to select which notes appear (by tag, folder, property, or date)
73. **Add formulas** (optional): Define computed properties in the `formulas` section
84. **Configure views**: Add one or more views (`table`, `cards`, `list`, or `map`) with `order` specifying which properties to display
95. **Validate**: Verify the file is valid YAML with no syntax errors. Check that all referenced properties and formulas exist. Common issues: unquoted strings containing special YAML characters, mismatched quotes in formula expressions, referencing `formula.X` without defining `X` in `formulas`
106. **Test in Obsidian**: Open the `.base` file in Obsidian to confirm the view renders correctly. If it shows a YAML error, check quoting rules below

12## Schema
13 
14Base files use the `.base` extension and contain valid YAML.
15 
16```yaml
17# Global filters apply to ALL views in the base
18filters:
19  # Can be a single filter string
20  # OR a recursive filter object with exactly ONE key: and, or, or not
21  and:
22    - 'status == "active"'
23    - not:
24        - 'file.hasTag("archived")'
25 
26# Define formula properties that can be used across all views
27formulas:
28  formula_name: 'expression'
29 
30# Configure display names and settings for properties
31properties:
32  property_name:
33    displayName: "Display Name"
34  formula.formula_name:
35    displayName: "Formula Display Name"
