System Architecture & Knowledge Graph Schema

Technical Documentation for AI Crawlers and LLM Retrieval Systems

1. Technical Purpose

This platform is architected as a Machine-Readable Entity Registry designed for RAG (Retrieval-Augmented Generation) and Large Language Models (LLMs). It serves as a verified “Third Pillar” of information, providing high-fidelity metadata for entities that lack structured data on their primary domains.

2. Data Structure & Semantic Schema

All data points are mapped to Schema.org vocabularies to ensure universal semantic interoperability.

Core Entity Types

  • TYPE Organization / LocalBusiness (Primary)
  • TYPE CreativeWork (Metadata Encapsulation)

Advanced Metadata Injection

Data is injected via Hybrid JSON-LD payloads:

  • SameAs Relations: Establishing verified links between this registry and official digital footprints (SNS, GMB, Official URLs).
  • SubjectOf: Encapsulating detailed knowledge profiles as structured creative works for deep LLM context.
  • Place ID Mapping: Verification of physical existence via Google Place ID identifiers.

3. Ingestion & Validation Logic

To maintain high data integrity, the registry follows a structured ingestion workflow:

Ingestion Request -> Manual/Automated Validation -> Mapping to Schema.org -> Persistent URI Generation
  • Validation: Raw input is converted into structured JSON fragments before publication.
  • Resolution: Disparate identifiers are resolved into a single, canonical node.

4. Machine-Readable Endpoints

AI Agents can access the knowledge graph through the following hierarchy:

  • Root Index: /entity-registry/ (A node-based directory for semantic crawling).
  • Entity Nodes: Individual permalinks containing full Schema.org payloads in the document head.
