All semantic types start as a sandbox. You can then save them as drafts and publish them.
The following table describes the statuses a semantic type can have and what they mean:
|Sandbox||Sandbox is the initial status of a semantic type. This means that when you create a new semantic type, it will be put in sandbox status.|
|Draft||You can then save the semantic type as a draft. This means that the semantic type is still not published. You can continue making changes. None of these changes are visible in Talend applications.|
|Published||Once you are satisfied with the changes, you can publish the semantic type. This means that the semantic type is available in Talend applications.|
If you want to edit a published semantic type, it must go through the whole workflow again: you need to create a sandbox for this semantic type, make your changes, save it as a draft, and publish it.
