When a dataset is set to be discoverable, it is listed in public search results and its metadata (description, summary, creator, and license), contributors, and discussion can be viewed by anyone on data.world. None of the individual files or tables in the dataset are visible, however. Only files that are explicitly marked as ‘Preview’ files are viewable by end-users until the end-user is granted read or write access to the dataset. The reason for the discoverable flag is to expose the existence of a dataset to others who might have a use for it, while at the same time maintaining control over who has can access the data in it. It is a useful tool for making users in other groups aware of the dataset so they can be granted permissions to it on an individual or group basis.
Setting a dataset as discoverable
Only a dataset that is owned by an organization (as opposed to an individual user) and which has its permissions set to private can be made discoverable. When a dataset is owned by an organization but set to private, it is not automatically shared with anyone else in the organization except the admins, even though it is set up for easy sharing with the entire organization at a later time from the Contributors tab. Making a dataset discoverable is done after the dataset has been created from the Settings tab:
When a dataset is discoverable this is what it looks like to everyone who doesn't have explicit permissions to it. Notice the indication under the summary that there are files in the dataset to which the viewer doesn't have permission:
When someone wants to see the rest of the dataset, they select the Request access button in the upper right of any tab on the dataset. The creator receives notice of the request in email and can then either approve or disapprove it:
Adding previews of data to a discoverable dataset
By default none of the files in a discoverable dataset can be previewed on the overview tab. However If you would like a sample of the data to show on the discoverable dataset, you can create sample files that are then marked as previewable. See our article on creating a sample file for preview on a discoverable dataset for details.
