Production IDP has its own vocabulary. Some terms are borrowed from adjacent fields and used loosely. Others are used precisely in one context and differently in another.
This glossary covers the terms that matter most in production document extraction pipelines — defined from two years of running live systems, not from vendor documentation.
Each entry explains what the term means, how it works in practice, and where it matters most. Where a concept warrants more depth, there’s a link to a full guide.
