When to Use

• Converting PDF documents to structured HTML
• Processing PowerPoint presentations for indexing
• Extracting semantic content from images via OCR
• Building document ingestion pipelines

Key Concepts

IngestPipeline: Orchestrates a sequence of transformation steps defined in config/ingest.yml.

IngestStep: Individual processing step (pdf-to-images, images-to-html, extract-context, annotate-html, normalize-html).

Usage Patterns

Pattern 1: Run ingestion via CLI

# Drop files in data/ingest/in/
cp document.pdf data/ingest/in/

# Run pipeline
make ingest

Pattern 2: Programmatic ingestion

import { IngestPipeline } from "@copilot-ld/libingest";

const pipeline = new IngestPipeline(config, storage, llmClient);
const result = await pipeline.process("document.pdf");
// result.output points to final HTML

Integration

Configured via config/ingest.yml. Uses libllm for vision processing. Output stored in data/ingest/pipeline/.
