Additions

Obsidian Additions

Two-level system for attaching supplementary materials to notes.

Architecture

Level 1: Aggregator (Space)

Container note in base/additions/ that groups additions by type. Tagged mark/addition/aggregator.

Level 2: Concrete Additions

Individual additions inside the aggregator space. Live in base/additions/ or subdirectories (e.g., base/additions/conspectuses/).

Addition Types

Workflow 1: Create Aggregator Space

Steps

1. Identify parent note — user specifies which note to attach addition to
2. Verify the note exists — use Glob to find it
3. Choose addition type — ask user which type from the table above
4. Check for duplicates — verify no aggregator with same name already exists in base/additions/
5. Create aggregator file in base/additions/
6. Update parent note — add wikilink to addition frontmatter property

Aggregator Naming

<parent note title> - <addition type>

Examples:

• Deep Learning - conspectuses.md
• Introduction to Statistics - practice.md
• My Project - experiments.md

Aggregator Frontmatter

---
tags:
  - mark/addition/aggregator
---

Update Parent Note's addition Property

Add a wikilink to the addition array in the parent note's frontmatter:

addition:
  - "[[<aggregator name>|<emoji>]]"

Example — if parent note is sources/Deep Learning.md and type is conspectuses:

addition:
  - "[[Deep Learning - conspectuses|📓]]"

Rules:

• If addition property doesn't exist — create it as a list with one item
• If addition property exists and is a list — append the new item
• If addition property exists but is empty — replace with a list containing the new item
• Preserve all existing items in the list

Workflow 2: Create Concrete Addition

Steps

1. Identify target aggregator — user specifies which aggregator or parent note
2. Verify the aggregator exists — use Glob in base/additions/
3. Create addition file based on type (see templates below)
4. Add wikilink to the concrete addition in the aggregator body as a list item (e.g., - [[My Project (2025-08-10) - meeting]])

Concrete Addition Naming

<parent note title> (<date>) - <addition type>

Date format: YYYY-MM-DD

Examples:

• My Project (2025-08-10) - experiments.md
• My Project (2025-08-10) - meeting.md
• My Project (2025-08-10) - reports.md

For conspectuses — use descriptive name instead of date:

• introduction to computer architecture.md (in base/additions/conspectuses/)

For conspectus notes: copy source type and category tags from the parent source note.

Body: semantic groups using collapsed [!abstract]- callouts. Links live directly in the aggregator — no separate concrete additions needed for this type.

Example group:

> [!abstract]- 💬 Chat & Inference
> - [Groq](https://groq.com/) · fast inference
> - [OpenRouter](https://openrouter.ai/) · model aggregator

Generic Addition (practice, annotations, AI, researches, etc.)

---
tags:
  - mark/addition/aggregator
---

Use the aggregator tag for generic containers. Body content is freeform.

Important Rules

• Always verify notes exist before linking — use Glob
• Never overwrite existing addition entries — only append
• Date format for all timestamps: ISO 8601 with timezone (YYYY-MM-DDTHH:mm:ssZ)
• Aggregator body is freeform markdown — the user organizes content within it
• Concrete additions go in base/additions/ or its subdirectories
• Conspectus notes specifically go in base/additions/conspectuses/
