使用预定义架构

重要提示：

To create a document type, we strongly recommend that you follow the "Create Document Type" flow in Document Understanding^TM. This will automatically populate the correct schema, reducing tedium and costly mistakes. If you want to use AI Center, follow the instructions below.

To use the retraining capability in AI Center, you need to use a set of fields based on the fields already extracted by the out-of-the-box pre-trained ML Packages offered by UiPath®. This list of fields is called a schema.

要创建预定义架构，请按照以下步骤操作：

1. 查看所需端点的完整字段列表。
   备注：

   Add the /info/model suffix to the URL of the endpoint you want to use. You can find the list public endpoints URL on the Public endpoints page. For example, https://du.uipath.com/ie/invoices/info/model. For an enhanced reading experience of the fields list, it's recommended to install a JSON viewer extension in your browser.

2. 复制“schema:{}”对象内部的内容。
   备注：

   Only the content between the curly brackets must be copied.

3. 将内容粘贴到您选择的编辑器中。
4. 使用 YourFile_schema.json 格式保存文件并命名。
