The Semantic Data Charter

A Neuro-Symbolic Blueprint for Verifiable Enterprise AI

The Enterprise AI Dilemma

While deep learning models are powerful, their "black box" nature creates significant risk in high-stakes enterprise environments. A lack of transparency, logical reasoning, and verifiability leads to a critical trust gap that hinders adoption and exposes businesses to liability.

The Semantic Data Charter (SDC) provides a solution by synthesizing symbolic AI (for structure and logic) with sub-symbolic AI (for pattern recognition), creating a foundation for AI systems that are not just powerful, but provably trustworthy.

The Four Pillars of Verifiable AI

RDF

Resource Description Framework

Provides a flexible, universal graph data model to represent complex relationships and knowledge.

OWL

Web Ontology Language

Enriches data with formal semantics and enables logical inference to discover new, implicit facts.

SHACL

Shapes Constraint Language

Acts as a data quality engine, validating that data conforms to predefined business rules and structural constraints.

GNN

Graph Neural Networks

Functions as the sub-symbolic learning engine, identifying statistical patterns to predict missing information in the graph.

The 5-Stage SDC Pipeline

The SDC operationalizes trust through a five-stage process that transforms raw data into a verifiable, intelligent knowledge asset. The pipeline ensures data quality from the start and validates AI-generated insights before they are accepted.

1

Model

Define data structures with semantic links to formal ontologies.

2

Constrain

Translate business rules into a machine-readable SHACL "shapes graph".

3

Populate

Transform and ingest data, validating it against SHACL rules.

4

Learn

Apply GNNs to the high-quality graph to predict missing links and insights.

5

Verify & Refine

Use SHACL as a "semantic guardrail" to validate GNN predictions before committing them.

Bootstrapping the Axius SaaS Platform

Multi-Tenant Foundation

To serve multiple customers securely and cost-effectively, the platform is built on a robust multi-tenant architecture using Django and PostgreSQL. Each tenant's data is isolated within its own database schema, providing strong security guarantees while maintaining operational efficiency.

  • Backend: Django Framework
  • Database: PostgreSQL with Schema-per-Tenant model
  • AI/ML Platform: Google Cloud Vertex AI

Graph Database Strategy: Balancing Cost & Performance

The choice of a graph database is critical. A bootstrapped startup must balance initial cost with long-term scalability. The strategy is to start with a powerful open-source solution and migrate to a commercial one as revenue grows.

The 4-Level Maturity Model: A Phased Path to Market

Axius, Inc. can de-risk its technical journey by adopting a phased maturity model. This approach aligns investment with revenue growth, ensuring each development stage delivers tangible value to customers and establishes a clear path to market leadership.

The Agentic Future: Intelligent Interaction

To make the SDC platform accessible to all users, not just engineers, Axius will leverage Vertex AI Agent Builder. These agents will provide a natural language interface to the platform's most complex features.

🗣️ The Modeling Agent

Users describe business rules in plain English. The agent then automatically generates the complex, formal SHACL constraints or XSD schemas, dramatically lowering the technical barrier to entry and accelerating time-to-value.

🔎 The Query Agent

Business analysts and executives can ask questions in natural language, such as "Which suppliers had late deliveries last quarter?". The agent converts the question to a formal SPARQL query, retrieves the answer from the graph, and presents it in a clear, understandable way.
