KMDS Workbench is a browser-native SPA designed to load, edit, and save OWL/XML knowledge bases, featuring prefix-agnostic ingestion and dynamic state synchronization. Utilizing a Python 3.13 backend and Dash interface, it enables direct semantic graph manipulation and node mutation without rigid namespace restrictions.

KMDS Workbench

An enterprise single-page workbench designed to ingest, manipulate, and serialize Knowledge Management Data Schema (KMDS) ontology graphs without prefix corruption or structural degradation.

💡 What is this Tool?

The KMDS Workbench is a specialized semantic data engineering interface built with Python 3.13, Dash, and rdflib. It bridges the gap between raw semantic OWL/XML data graphs and human analysts. It provides an isolated runtime workspace to:

• Ingest complex OWL/XML ontology files via simple drag-and-drop actions.
• Visualize raw semantic triples instantly inside a proportional, word-wrapped data grid.
• Mutate specific observation type predicates and literal text elements on the fly.
• Serialize updated in-memory graph models back to disk while maintaining exact original filenames.

🚀 How to Use It

1. Installation & Environment Setup

This repository utilizes uv for isolated, reliable workspace package management.

Clone the repository and spin up the enterprise application server:

# Clone the repository
git clone https://github.com
cd kmds

# Install dependencies and start the Dash local server runtime entry point
uv run python src/kmds_ui/app.py

The terminal will output a local network address (typically http://127.0.0). Open this URL in your web browser.

2. Ingesting an OWL Knowledge Base

• Drag and drop your .owl or .xml target ontology file directly into the dotted Upload Control Area.
• The application decodes the base64 byte array in-memory via an internal io.BytesIO wrapper.
• The Diagnostic Indicators card updates instantly, revealing the total count of parsed RDF triples alongside the formatted observation table records.

3. Modifying Knowledge Base Elements

• Click the selection checkbox next to any row inside the Observation Grid.
• An enterprise transactional modal will slide into view, pre-populated with that node's structural data.
• Select a new sub-class configuration from the drop-down menu, or overwrite text elements within the Literal Text Content Overwrite Narrative text area.
• Click OK. The underlying active_graph immediately commits the changes using precise string data-type declarations.

4. Exporting the Mutated State

• Click the green Export KMDS Graph State button.
• The application automatically triggers your web browser's native download workflow.
• Zero Overhead Configuration: The output module automatically pairs your updated payload with the exact file name captured during step 2, eliminating manual renames or broken file associations.
