When creating datasets and projects in data.world, you will select whether to make them open (visible to the public) or private.
Public, open datasets and projects will be visible, in their entirety, to anyone signed into data.world. They could be returned in search results, will be visible under your profile, and will be available for querying and downloads. No other members will be able to change the dataset or project without explicit permission from you. See How to add collaborators for instructions on granting addition permissions to others.
Private datasets and projects will be completely invisible to other data.world members unless you explicitly grant them access. They will not show up in searches, and even if someone knows the URL, they will see "Oops! We can't find that page".
Setting permissions on new datasets and projects
When creating a dataset or project, you must select whether to make it open or private.
By default, the accessibility is set to private.
Private datasets and projects will only be searchable and accessible by the creator.
If you're a part of an organization, then you'll also have the option to create the dataset or project within the organization instead of your personal account. In this case, you can make it available to just yourself or make it available to that organization but not the public.
In the following screenshot, I've joined the dw-support organization and am creating the project within the organization's account instead of in my personal account. That's specified in the Owner section. I've also shared it with that organization in the Share with section. Note that it's also possible to make the project with the organization as the owner but make it visible only to the individual. You might want to do this if you don't want other organization members to see it until it's finished. You can make it private at first and then share it with the organization later once it's done.
This project will be hidden from the data.world community, but available to other organization members. By default, organization members will receive View only privileges (but they can be granted Edit and Manage privileges later - see Understanding permissions for more info on that).
If you would like to have the project or dataset be available to the entire data.world community, then click on the Make public to data.world community link in the Share with section of the screenshot shown above. You can do this whether you're making the asset within your personal account or within an organization account.
If you've already used your allowance of private projects/datasets, then new ones must be publicly shared. To increase the number of allowed private assets, you can upgrade your account in the Billing tab within your account settings.
