Obsidian Bases Skill

Workflow

1. Create the file: Create a .base file in the vault with valid YAML content
2. Define scope: Add filters to select which notes appear (by tag, folder, property, or date)
3. Add formulas (optional): Define computed properties in the formulas section
4. Configure views: Add one or more views (table, cards, list, or map) with order specifying which properties to display
5. 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
6. 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

Schema

Base files use the .base extension and contain valid YAML.

# Global filters apply to ALL views in the base
filters:
  # Can be a single filter string
  # OR a recursive filter object with and/or/not
  and: []
  or: []
  not: []

# Define formula properties that can be used across all views
formulas:
  formula_name: "expression"

# Configure display names and settings for properties
properties:
  property_name:
    displayName: "Display Name"
  formula.formula_name:
    displayName: "Formula Display Name"
  file.ext:
    displayName: "Extension"

# Define custom summary formulas
summaries:
  custom_summary_name: "values.mean().round(3)"

# Define one or more views
views:
  - type: table | cards | list | map
    name: "View Name"
    limit: 10 # Optional: limit results
    groupBy: # Optional: group results
      property: property_name
      direction: ASC | DESC
    filters: # View-specific filters
      and: []
    order: # Properties to display in order
      - file.name
      - property_name
      - formula.formula_name
    summaries: # Map properties to summary formulas
      property_name: Average
