Data Spaces in Data Cloud act as logical partitions to segregate data, metadata, and processes. When a data stream is created, its associated Data Lake Object (DLO) and any mapped Data Model Objects (DMOs) are assigned to that data stream's designated data space. To make these objects available for use (e.g., for mapping, segmentation, or activation) in a different data space, an administrator must explicitly edit the target data space's configuration and add the desired objects. This action shares the object's metadata, making it accessible without duplicating the underlying data.

"Data Spaces": "After you create a data space

you can add and remove objects

such as data streams

data lake objects

and data model objects." This statement confirms that objects are managed at the data space level.

"Edit a Data Space": "To control which objects are available in a data space

add or remove them from the data space record... From the Data Spaces tab

select the data space that you want to edit... To add objects

click Edit

and select the objects." This section provides the exact procedural steps described in the correct answer.

"Data Mapping and Data Spaces": "When you map a data stream to a data model object (DMO)

the DLO and DMO are assigned to the data stream’s data space. To make the DLO and DMO available in other data spaces

add them to the other data spaces." This directly addresses the scenario in the question.
