# semantic-web
## Goal
To architect machine-readable data structures using Semantic Web standards (RDF, OWL, SPARQL) allowing disparate enterprise systems and AI agents to share a unified, interoperable meta-knowledge graph.
## Steps
1. **Domain Modeling**: Analyze the business entities and define the formal Vocabulary/Ontology using OWL (Web Ontology Language).
2. **Data Transformation**: Design pipelines to map existing relational or document data into RDF triples (Subject-Predicate-Object).
3. **Query Interface**: Outline the SPARQL endpoints required for human and agent interaction with the Knowledge Graph.
4. **Output**: Generate the formal definitions and structure using `agents/templates/data/ONTOLOGY_TEMPLATE.md`.
## Security & Guardrails
### 1. Skill Security
- **SPARQL Injection**: Ensure the agent explicitly enforces parameterized queries when designing applications that interface with graph databases to prevent malicious graph traversals.
### 2. System Integration Security
- **Inference Leakage**: Agents must account for automated inference engines (reasoners) inadvertently linking two unclassified data points to deduce classified information (aggregation attacks).
### 3. LLM & Agent Guardrails
- **URI Standardization**: The LLM must not hallucinate random namespaces. It must use established ontologies (e.g., `schema.org`, `foaf`, `dublin core`) before inventing custom property URIs.
