Every object in Islandora can also be set to one or more "states" in Fedora. Fedora states include "Active," "Inactive," or "Deleted." These states are used in different ways by Islandora code. By default, only "Active" objects show up in collections and are indexed by Solr, but all objects regardless of state display to anonymous users with permission to view repository objects. Inactive states can be used The Islandora Simple Workflow module uses the 'Inactive' state for objects that aren't ready to be published (for example, objects waiting for approval in an ingest workflow). Objects can also be set to a state of "Deleted," which maintains a copy of the object in the repository but restricts viewing and management to certain rolesthough this (like the 'Inactive' state) merely means that they will not show up in normal navigation, though these objects can still be navigated to directly. This is in contrast to purging an object, which permanently removes the object and its administrative history from the repository.
