With the release of the Publishing Workflow, the process by which data publishers manage their datasets will change slightly.

One of the core principles of the Publishing Workflow is that all datasets now have two states - "Published" and "Working Copy". The Published version is the one you show to the rest of the world, while the Working Copy is the one that's reserved for you and your collaborators to make edits on. In order to make modifications to your datasets, you'll need to make them against the Working Copy and then republish them back to the Published version. For details on the concepts behind the Publishing Workflow, see "An Overview of the Publishing Workflow".

The steps to create a Working Copy, make modifications, and then republish them to the world are as follows:

1. Browse to the dataset you'd like to update, and click on "Edit Dataset" within the "Edit" sidebar. This will create a new Working Copy for your dataset, or take you to the existing Working Copy if one has already been created. If you have a very large dataset, you may have to wait while your copy is created.
2. Make whatever changes you'd like to make to your dataset. Since these changes are made against the Working Copy and not against the Published version, you can review your changes and share them internally with others without worrying that they will be available to the public.
3. When you're done making your changes, click on "Publish Dataset" next to the dataset title. This will make your Working Copy the new Published version, and will make the old Published version into a Snapshot. Your changes are now live on your data site.
