Proactive schema design for document extraction anticipates rare variants

Designing an effective extraction schema for documents like invoices requires anticipating rare variants from the outset, rather than iterating after encountering errors. The standard approach of building a schema from common examples and then fixing it when exceptions arise is inefficient. Instead, developers should proactively identify all known subtypes and regulatory requirements for a document type before creating the schema, designing for the most complex variant first. This proactive approach, which involves answering specific questions about subtypes, mandated fields, and jurisdictional variations, prevents costly schema evolution later in the development cycle.
