Inventory

The inventory is used by PlayerCharacter for:

Collecting game objects like items, documents and weapons and then performing some specific operations on them (such as inspecting a document, using an item or equiping a weaopn)
Visualizing the currently opened missions
Navigate currently discovered game map

The Inventory is managed by the Player in the same way he does with the HUD:

There is a pre-defined structure in which every active element is recognized and updated by the Player. The Player recognize active elements by their names, that are pre-defined as for the HUD.

The Inventory structure is based on a list of Tabs.
