freeplane-and-yaml 0.1.2

A tool to convert YAML files to Freeplane MM format

YAML to Freeplane Converter

A Python tool that converts YAML files into Freeplane mind maps. This allows you to generate mind maps programmatically from structured YAML data.

The YAML file can be created using Claude AI. A suitable prompt is given below.

You can read about how it got written using AI on medium. That's a friend link so you can read it even if you're not a subscriber.

Installation

This project requires Python and should be run in a virtual environment:

# Create and activate virtual environment in the direcoty of your choice
python -m venv venv
source venv/bin/activate  # On Windows use: venv\Scripts\activate
pip install freeplane-and-yaml

Usage

Your YAML file should follow this schema. Here's an example structure:

root:
  title: "Your Main Topic"
  note: "Optional note for the main topic"
  children:
    subtopic1:
      title: "Subtopic 1"
      note: "Optional note for subtopic 1"
      children:
        # ... more nested topics
    subtopic2:
      title: "Subtopic 2"
      # ... and so on

Converting YAML to Mind Map

To convert a YAML file to a Freeplane mind map:

# Convert YAML and store mind map in temp
convert data/marr.yaml temp

YAML Schema Requirements

The YAML must conform to these rules:

• Must have a root node with a title and at least one child
• Each node requires a title
• Notes are optional
• Child node keys must be alphanumeric (including underscores)
• No additional properties are allowed beyond title, note, and children

For full schema details, see schema.

Converting Documents to YAML using Claude AI

You can use Claude Sonnet to automatically convert documents (PDFs, articles, specifications, etc.) into the required YAML format. Here's the workflow:

1. Share your document and the schema with Claude Sonnet.
2. Use this prompt:

   I've uploaded a document and a schema file.  I'd like you to summarise the document as a yaml file following the schema that I uploaded.
   

3. Claude will generate a YAML file that follows the schema
4. Save Claude's output as a .yaml file
5. Convert it to a mind map using this tool

This workflow is useful for:

• Summarizing academic papers
• Converting product requirements documents (PRDs)
• Creating structured summaries of technical documentation
• Organizing research notes

The generated .mm file can be opened in Freeplane. When you first open the file, Freeplane will show this warning dialog because the file wasn't created by Freeplane itself:

This is normal and expected — click OK to load the mind map.

Here's an example of how the output looks:

Features

• Converts YAML structured data to Freeplane mind map format
• Supports hierarchical node structure
• Includes node titles and optional notes
• Automatically alternates between right and left positions for top-level nodes
• Generates unique IDs for each node
• Validates input against JSON schema
