# 27. Mutation: Save "Note" attached to "SoilDataset"

This mutation allows you to attach a Note to a specified SoilDataset.

* A Note can be linked to the Field via its unique identifier `fieldUuid` and to the associated SoilDataset via `soilDatasetUuid`.
* The coordinate of the Note can be set using the `centroid` attribute, which requires defined `latitude` and `longitude` values. 
* The type of Note can be specified using the `type` attribute with acceptable values of `PLANNED` or `REAL`. 
* The description of the Note can be provided using the `comment` attribute. If the description needs to be multiline, the `comment` attribute should contain a string with newline characters `\\n` to separate lines. For example: `"First line. is here\\nSecond line is here.\\nThird line is here."`.

The sample requests can be found below:
