Ingestion, cleaning, and chunking

• Prepare documents before converting them into vectors.
• Choose a chunking strategy based on document type.
• Store metadata for permissions, citations, and auditing.

Minimum metadata

{
  "document_id": "contrato-2026-001",
  "title": "Contrato proveedor",
  "source": "drive/legal/contrato.pdf",
  "page": 12,
  "section": "penalizaciones",
  "owner": "legal",
  "visibility": "internal",
  "updated_at": "2026-07-02"
}

Chunking strategies

• By headings: manuals, policies, technical documentation.
• By page: contracts, case files, PDFs with page-level citations.
• By table: invoices, catalogs, inventories.
• With overlap: narrative text where an idea spans paragraphs.
