RDF Diagram Framework

A comprehensive toolkit for creating, editing, and converting visual RDF graph representations. An RDF-Diagram can express all concepts of RDF 1.1 (except RDF Datasets).

• Try it: Draw.io with RDF-D Plugin
• Read the Specification

This is an RDF-Diagram created with Draw.io:

and it directly translates to turtle:

Overview

The RDF-Diagram-Framework provides a standardized visual language for RDF graphs, making them more accessible and easier to understand. It offers a complete ecosystem of tools for working with RDF diagrams, from visual editing to programmatic manipulation.

Key Components

Draw.io Plugin

• Visual RDF graph creation and editing
• Real-time syntax and RDF-Diagram validation
• Auto-completion for RDF terms
• Integrated shape library
• Live RDF preview
• Export to Turtle

Command-Line Interface

• Convert from Draw.io RDF-Diagrams to RDF serializations (Turtle and N-Triples)
• Support for multiple RDF formats
• Batch processing capabilities

Library

• Available for Rust and JavaScript
• RDF conversion utilities

Specification

• Comprehensive visual language definition
• Covers RDF 1.1 (except RDF Datasets)
• Syntax is equivalent to Turtle 1.1
• Semantic mappings of diagram elements to RDF
• Best practices and examples

Usage

Using the Draw.io Plugin

1. Visit Draw.io with RDF-D Plugin
2. Use the RDF shapes from the library panel
3. Create your RDF diagrams
4. Access the RDF preview via the RDF Panel button

Installing the CLI

git clone git@gitlab.com:infai/rdf-diagram-framework.git
cd rdf-diagram-framework
cargo install --path=rdf-diagram-cli

Using the Library

cargo install rdf-diagram-lib

use rdf_diagram_lib::{drawio_to_turtle, Result};

let xml = include_str!("diagram.drawio");
let turtle = drawio_to_turtle(&xml)?;
