**Table 1** Data management APIs
Type	API	Description
Dataset Management	Querying the Dataset List	Query created datasets by page based on specified conditions.
	Creating a Dataset	Create a new dataset and determine whether to enable team labeling. Enable team labeling. The subsequent operations vary depending on the specified role. If a team is specified to assign labeling tasks, the team labeling task is started after the dataset is created. If a task manager is specified to assign labeling tasks, the manager calls the API in Starting a Team Labeling Task to assign and start the team labeling tasks. Disable team labeling. To enable team labeling later, call the API in Creating a Team Labeling Task to create team labeling tasks for the dataset.
	Querying Details About a Dataset	Query details about a dataset, including the dataset name, type, and version name based on the dataset ID.
	Modifying a Dataset	Modify basic information about a dataset, such as the dataset name, description, version, or labels. The modification takes effect in the entire dataset, including the samples in the dataset.
