What is obsidian-bases?

A guide for Obsidian Bases, Obsidian's built-in feature for creating interactive database views from notes and their YAML properties. It covers .base files, filters, formulas, and table or card views.

It is for building and editing Obsidian Bases, including queries, computed fields, filters, and views based on note frontmatter.

It helps create structured, sortable note views without needing a separate community plugin or guessing the required YAML format.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00049	$0.02565
Opus 5.5	$0.00020	$0.01026
Sonnet 5.5	$0.00010	$0.00513
Haiku 4.5	$0.00005	$0.00257

Security

Grade A, and why

obsidian-bases scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Obsidian Bases

Expert knowledge for creating and managing Obsidian Bases - the interactive database feature introduced in Obsidian v1.9.10 that transforms notes into filterable, sortable views using YAML frontmatter properties.

Core Concepts

What is Bases?

Native core plugin (no community plugins required)
Creates interactive database views from any set of notes
Uses .base file extension (plain-text YAML format)
Only reads YAML frontmatter - does not parse note content
Faster performance than Dataview with inline editing support

Key Distinction from Dataview:

Bases: User-friendly, visual, inline editable, YAML frontmatter only
Dataview: More powerful queries, inline properties, content parsing

File Structure

# example.base
filters:
  # Global filters (apply to all views)
  and:
    - 'status != "done"'
    - taggedWith(file.file, "project")

formulas:
  # Computed properties
  days_left: '(dueDate - today()).days()'
  status_icon: 'if(done, "✅", "⬜")'

views:
  - type: table
    name: "Active Tasks"
    filters:
      'dueDate > now()'      # View-specific filter
    properties:
      - name: title
        displayName: "Task"
      - name: status
      - name: dueDate
    sort:
      - property: dueDate
        direction: asc

  - type: card
    name: "Visual View"
    properties:
      - name: cover
      - name: title

Property Access Patterns

Note Properties (Frontmatter)

# Shorthand access
price
status
tags

# Explicit prefix
note.price
note.status

# Bracket notation (for spaces)
note["property name"]

File Properties (Implicit)

file.path      # Full file path
file.name      # File name only
file.folder    # Parent folder
file.size      # File size in bytes
file.ctime     # Creation time
file.mtime     # Modification time
file.ext       # Extension
file.file      # File object (for filter functions)
file.links     # Outgoing links
file.inlinks   # Incoming backlinks

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
