Gerenciar esquemas de documentos

Este documento descreve como gerenciar os esquemas de documentos na Document AI Warehouse, incluindo operações de criação, busca, listagem, atualização e exclusão.

O que são esquemas de documentos

Cada documento é de um determinado tipo e é especificado por um esquema.

Um esquema de documento define a estrutura de um tipo de documento (por exemplo, fatura ou contracheque) na Document AI Warehouse, em que os administradores podem especificar propriedades de diferentes tipos de dados (texto | numérico | data | enumeração).

As propriedades são usadas para representar os dados extraídos, tags de classificação ou outras tags comerciais anexadas a documentos por usuários de IA ou humanos. Por exemplo, Invoice_Amount (numérico), Due_Date (data) ou Supplier_Name (texto).

Atributos de propriedade:cada propriedade pode ser declarada como
1. Filtrável: pode ser usado para filtrar resultados da pesquisa
2. Pesquisável: indexado para que possa ser encontrado em consultas de pesquisa
3. Obrigatório: required é usado para garantir que a propriedade exista em o documento (Recomendamos salvar a maioria das propriedades como required = false, a menos que a propriedade seja obrigatória.)
Esquema extensível:em alguns casos, os usuários finais com acesso de edição precisam adicionar / excluir novas propriedades de esquema em documentos. Isso é compatível com uma "propriedade MAP", que é uma lista de pares de chave-valor.
1. Cada par de chave-valor em uma propriedade MAP pode ser um tipo de dados de (texto | numérico | data | enumeração).
2. Por exemplo, a fatura pode conter uma propriedade de mapa "Invoice_Entities" com os seguintes pares de chave-valor:
  - Invoice_Amount (numérico) 1000
  - Due_Date (data) 24/12/2021
  - Supplier_Name (texto) ABC Corp
3. Imutabilidade do esquema:os esquemas ou propriedades de esquema podem ser adicionados, mas não podem ser editados ou excluídos. Portanto, defina o esquema com cuidado.

Atualizar um esquema

Atualize um esquema de documento. No momento, a lógica de atualização só oferece suporte à adição de novas definições de propriedade. O novo esquema de documento precisa incluir todas as definições de propriedade presentes no esquema atual.

Com suporte:
- Para propriedades atuais, os usuários podem mudar as seguintes configurações de metadados: is_repeatable, is_metadata, is_required.
- Para propriedades ENUM atuais, os usuários podem adicionar novos valores possíveis de ENUM ou excluir valores possíveis de ENUM. Eles podem atualizar a flag EnumTypeOptions.validation_check_disabled para desativar a verificação de validação. A verificação de validação é usada para garantir que os valores ENUM especificados nos documentos estejam no intervalo de valores ENUM possíveis definidos na definição de propriedade ao chamar a API CreateDocument.
- A adição de novas definições de propriedade é compatível.
Indisponível:
- Para o esquema atual, não é permitido atualizar display_name e document_is_folder.
- Para propriedades atuais, não é permitido atualizar name, display_name e value_type_options.
