Input datasets of the project are regrouped in this first zone.

The three input datasets are:
- [example_documents](managed_folder:008vhkiq). The folder contains all the documents that will be processed in the flow. The user can add them through the Project Setup. The document can consist of various file types (e.g. pdf, jpeg, png, tiff, etc.) and can be either directly searchable or not.
- [input_metadata](dataset:input_metadata). This dataset contains information that will be used later in the flow to represent the outputs of the project. It must contain three mandatory columns: **file_name** (string, name of the document), **name** (string, name of the entity related to the document), **date** (date, date of the document). Each row represents a document in the folder above.
- [keywords](dataset:keywords). The lists of keywords that will be searched for in the documents. Each row represents a category, and then keywords are listed underneath. All categories do not need to have the same number of keywords.
