About the Document Processing Contracts
The UiPath.DocumentProcessing.Contracts, a.NET assembly, lets you combine your classification and extraction activities with the IntelligentOCR activities package. By referencing the contracts, you can implement any activities.
UiPath.DocumentProcessing.Contracts is automatically installed with any other Document Understanding package in your automations. This package contains the class definitions for all the objects that are used throughout the document processing framework. Use these classes to perform CRUD (Create, Read, Update, Delete) operations on the objects that the document processing framework is using.
