[lpugin]

Inventories in Muscat bring two new record types for sources to be adjusted here

• 12: inventory
• 13: inventory_edition

12 needs to be mapped to manuscript, and 13 to print source type.

The content type shows as Inventory, which is fine. However, it is missing a the translation and a content type (yellow) icon.

(unspecified source type and the blank green icon will disappear)

This will probably disappear when the source is unpublished.

[lpugin]

Yes. And no new source type will be needed when we publish them. Only the content type.
