--- name: obsidian-bases description: Create and edit Obsidian Bases (.base files) with views, filters, formulas, and summaries. Use when working with .base files, creating database-like views of notes, or when the user mentions Bases, table views, card views, filters, or formulas in Obsidian. --- # 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. ``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 ` ## Filter Syntax Filters narrow down results. They can be applied globally or per-view. ### Filter Structure `yaml # Single filter filters: 'status == "done"' # AND - all conditions must be true filters: and: - 'status == "done"' - 'priority > 3' # OR - any condition can be true filters: or: - 'file.hasTag("book")' - 'file.hasTag("article")' # NOT - exclude matching items filters: not: - 'file.hasTag("archived")' # Nested filters filters: or: - file.hasTag("tag") - and: - file.hasTag("book") - file.hasLink("Textbook") - not: - file.hasTag("book") - file.inFolder("Required Reading") ` ### 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. **Note properties** - From frontmatter: note.author or just author 2. **File properties** - File metadata: file.name, file.mtime, etc. 3. **Formula properties** - Computed values: formula.my_formula ### File Properties Reference | Property | Type | Description | |----------|------|-------------| | file.name | String | File name | | file.basename | String | File name without extension | | file.path | String | Full path to file | | file.folder | String | Parent folder path | | file.ext | String | File extension | | file.size | Number | File size in bytes | | file.ctime | Date | Created time | | file.mtime | Date | Modified time | | file.tags | List | All tags in file | | file.links | List | Internal links in file | | file.backlinks | List | Files linking to this file | | file.embeds | List | Embeds in the note | | file.properties | Object | All frontmatter properties | ### The this Keyword - In main content area: refers to the base file itself - When embedded: refers to the embedding file - In sidebar: refers to the active file in main content ## Formula Syntax Formulas compute values from properties. Defined in the formulas section. ``yaml formulas: # Simple arithmetic total: "price * quantity" # Conditional logic statusicon: 'if(done, "✅", "⏳")' # String formatting formattedprice: 'if(price, price.toFixed(2) + " dollars")' # Date formatting created: 'file.ctime.format("YYYY-MM-DD")' # Calculate days since created (use .days for Duration) days_
