SDC Studio Sovereign - Axius SDC | Air-Gapped Data Sovereignty

Built for Sovereignty

Every component runs inside your network. No telemetry, no cloud calls, no data exfiltration vectors.

Air-Gapped Deployment

Complete network isolation. Delivered as a self-contained package — no outbound connections required at any point. Operate on classified networks, SCIFs, or any environment where data must never leave the perimeter.

Local LLM (Ollama)

AI-powered semantic modeling with qwen2.5:7b-instruct running entirely on-premises via Ollama. All inference stays on your hardware. No prompts or data sent to external APIs.

ECDSA Signing

Cryptographic integrity with local ECDSA P-256 keys. Sign and verify data models without relying on cloud HSMs. Your signing keys never leave your infrastructure.

GraphDB + OWL 2 RL

Graphwise GraphDB with OWL 2 RL reasoning as the enterprise triplestore. Production-grade semantic reasoning, SPARQL 1.1 support, and automatic inference over your knowledge graph.

LDAP Authentication

Enterprise directory integration out of the box. Authenticate users against your existing Active Directory or OpenLDAP infrastructure. No external identity providers required.

AI That Learns Your Domain

Your sovereign AI assistant accumulates knowledge about your specific data architecture, components, workflows, and conventions over time - in human-readable files on your hardware. No model retraining required. No data leaves your building. You can read, edit, and audit everything it learns.

Docker Compose

Single-command deployment with a 7-service Docker Compose stack. No Kubernetes required. Reproducible, auditable, and simple enough for any infrastructure team to operate.

10-Service Architecture

Core platform plus XMI2SDC conversion agents, all in Docker Compose

Web (Django / Daphne)

ASGI application server with WebSocket support. React SPA + Django templates.

Celery Worker

Async task processing for data parsing and agentic model generation.

Celery Beat

Periodic task scheduler for maintenance and background operations.

PostgreSQL + pgvector

Primary data store with vector embeddings for RAG-powered semantic search.

Redis

Message broker for Celery tasks and caching layer.

Graphwise GraphDB

Enterprise triplestore with OWL 2 RL reasoning. SPARQL 1.1 endpoint for semantic queries.

Ollama (qwen2.5:7b-instruct)

Local LLM inference server. AI-powered semantic modeling without external API calls.

XMI2SDC Conversion Agents

XMI Parser

Reads UML models (XMI 2.1) from Sparx EA, MagicDraw, StarUML. Fully offline.

SDC Mapper

Maps UML classes and attributes to SDC component types. Deterministic, fully offline.

SDC Assembler

Submits mapping plans to the Assembly API to create data models. Calls SDCStudioSov at localhost:8000.

Included in Sovereign Distribution

XMI2SDC

Convert UML models from enterprise modeling tools directly into SDC4-compliant data models. No manual re-entry, no cloud dependency.

Import From Any UML Tool

XMI2SDC reads XMI 2.1 exports from Sparx Enterprise Architect, MagicDraw, StarUML, and other UML tools. A three-agent pipeline parses the model, maps UML types to SDC components, and assembles the result into a complete data model in SDCStudioSov.

Parser extracts classes, attributes, enumerations, and associations from XMI files. Fully offline.
Mapper converts UML types to SDC component types (XdString, XdQuantity, Cluster, etc.). Deterministic, fully offline.
Assembler submits the mapping plan to SDCStudioSov's Assembly API. The only agent that makes a network call (localhost only).

Deployment Details

Delivery

Included in the sovereign evaluation tarball. Separate docker-compose.xmi2sdc.yml alongside the main stack.

Services

3 persistent MCP servers (parser, mapper, assembler) + CLI for one-shot commands.

Network

All containers use network_mode: host. Parser and mapper are fully offline. Assembler reaches SDCStudioSov at localhost:8000.

MCP Integration

Each agent exposes tools via the Model Context Protocol. Works with Claude Desktop, Claude Code, and Cursor out of the box.

Telemetry

All OpenTelemetry exporters disabled at the image level. Zero phone-home.

Quick Start

# Configure
cp xmi2sdc.example.yaml xmi2sdc.yaml
export SDC_API_KEY="eval-token-2026"

# Start MCP servers
docker compose -f docker-compose.xmi2sdc.yml up -d --build

# Convert a UML model
docker compose -f docker-compose.xmi2sdc.yml run --rm xmi2sdc convert /data/model.xmi

# Assemble into SDCStudioSov
docker compose -f docker-compose.xmi2sdc.yml run --rm xmi2sdc assemble /home/sdc/output/model_mapping.json --title "My Model"

Two Paths to Sovereignty

Whether you're bridging from legacy systems or building greenfield infrastructure, the Sovereign Suite meets you where you are.

Path 1: Bridge to Sovereignty

Legacy systems (SAP, Oracle, custom databases) continue operating. A pipeline feeds existing data into SDCStudioSov, which models it as SDC4-compliant structures and populates the sovereign knowledge graph. No rip-and-replace required.

Path 2: Greenfield Sovereignty

SDCStudio generates new sovereign applications that ingest legacy data once during standup, then the old systems decommission. New systems are native SDC from day one — fully interoperable, self-describing, with no ongoing ETL pipelines or migration debt. This is the leapfrog path.

Greenfield Sovereignty: SDCStudioSov generates native sovereign applications, legacy data ingested once, no ongoing pipelines

Cloud vs. Sovereign

Same SDC compliance. Same output formats. Different deployment model.
