Module content Architecture

Architecture - Content Module

Overview

The content module composes ingestion, extraction, validation, enrichment, and storage-integration surfaces into a unified content-processing runtime. It provides deterministic routing from content type detection through processor execution and post-processing stages.

Main Execution Planes

1. Ingestion and routing plane

• mime/content classification and processor selection
• sync and async ingestion orchestration paths

2. Validation and security plane

• schema/format validation and policy enforcement
• archive/content safety checks and bounded rejection behavior

3. Extraction and enrichment plane

• format-specific extraction (text, image, PDF, Office, audio/video)
• OCR, language, LLM, and embedding integration paths

4. Deduplication and operations plane

• hash/perceptual deduplication checks
• metrics, logging, versioning, and plugin extension surfaces

Core Contracts

Contract	Behavior
ingestion interfaces	deterministic content intake and processor routing
validation/security interfaces	explicit pre-processing gates and failure semantics
extraction/enrichment interfaces	format-aware extraction and optional enhancement paths
operations interfaces	stable metrics/audit/plugin extension behavior

Failure Semantics

• unsupported or invalid inputs fail with structured content errors.
• dependency-degraded processors return explicit non-silent failure states.
• policy/security violations fail closed before downstream processing.
