Here is a tutorial that describes how to save the target dataset from one project to a new project.

For example we have the project "lemon_merged" which contains datasets "ds_annotated", "ds_test" and we want to save the dataset "ds_annotated" to the new project "lemons_annotated".

Step 1. Go to the DTL page.

Step 2. Write the DTL query.

The first layer defines the project and dataset we will use. The second is the Dataset layer that moves data flow to the selected dataset. The third layer just saves all input data to the new lemons_annotated project.

Here is the DTL query from our example:

[
  {
    "action": "data",
    "src": [
      "lemon_merged/ds_annotated"
    ],
    "dst": "$sample",
    "settings": {
      "classes_mapping": "default"
    }
  },
​
  {
    "action": "dataset",
    "src": ["$sample" ],
    "dst": "$output",
    "settings": {
      "name": "ds1"
    }
  },
​
  {
    "action": "supervisely",
    "src": [
      "$output"
    ],
    "dst": "lemons_annotated",
    "settings": {}
  }
]

Step 3. View results.

When the task is finished, the new project "lemons_annotated" will appear on the "Projects" page. It will contain 1 dataset "ds1".

Here is the result:
