When you create a new silo under sitecore → Media Library → Digizuite, the item gets a unique Item ID. This ID is used to generate all items itemId, when synchronizing the silo against Digizuite™ DAM.

The silo is a bucket containing all the assets available from Digizuite™ DAM, represented as an item and the ItemId for each item is calculated from this formula: AssetId + Silo ItemId.
This means that the itemId is always the same, for a specific asset, when its being deleted and synchronized again.

The silo configuration located at sitecore → System → Modules → Digizuite → MetaDataRoot_0, has the same logic as above around generating the ItemId.

When you are working multiple developers together on the same solution, then you have to make sure that every one has a silo item with the same itemId. Then when every developer synchronizes the silo, all the items + configurations has the same itemId between developers.
