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. Filter Syntax Filters narrow down results. They can be applied globally or per-view. Filter Structure Filter Operators Operator Description ---------- ------------- == equals != not equal > greater than < less than >= greater than or equal <= less than or equal && logical and \ \ logical or <code>!</code> logical not Properties Three Types of Properties 1.
