What it is Filled
An item is an object within a game that a player or game character can collect or otherwise obtain, with possession, use and effects governed by that game's rules.
In scope
- An item's identity includes its game context and any distinction between an item type and an individual instance.
- An item's attributes may include condition, rarity, equipment compatibility and permitted uses.
- Acquisition and possession include availability, inventory membership and applicable eligibility restrictions.
- Item effects include their significance for play and any conditions limiting their applicability.
- Transfer, consumption and loss are governed by the game's rules and any applicable user authorization.
Out of scope
- The complete rules, world and progression structure of the game remain outside this model.
- Player accounts and character identities are separate entities linked to item possession.
- Background scenery that cannot be collected or otherwise obtained is outside this sense.
- Bibliographic exemplars and general catalogue entries are separate senses of item.
- Marketplace operations and payment systems are outside scope except where their restrictions affect an item.
Why it exists Filled
Enable an AI agent to recognise obtainable game objects, interpret their attributes and availability, and determine permitted acquisition, use or transfer under the game's rules and the user's authorization.
Distinguishing features Filled
- An item must be collectible or otherwise obtainable within its game context.
- An item type may have multiple instances or stackable units with different possession records.
- Similar names or appearances do not establish equivalent effects across games or versions.
- An item may serve equipment, consumable, quest, cosmetic or other roles defined by the game.
- Possession does not by itself establish permission to use, transfer or sell an item.
What robots and AI may and may not do Filled
Must not
- Consume, discard, transfer or spend resources on items without user authorization.
- Misrepresent an item's identity, rarity, effects, value or transfer restrictions.
- Facilitate item scams, account theft or unauthorized access to another player's inventory.
- Bypass game rules or access restrictions to obtain or duplicate items.
Only with a human decision
- Resolving disputed ownership or authorization for an item transaction requires human review.
- Approving irreversible item actions or real-money transactions outside existing user authorization requires human involvement.
May
- Describe an item's attributes, availability and effects using information appropriate to the game and version.
- Help users compare and organise items within the game's rules.
- Perform authorized item actions within the user's stated limits and the game's rules.
Moral aspects Filled
- Item descriptions and offers should accurately represent restrictions, costs and uncertainty.
- Item actions can affect a player's invested time, money and enjoyment.
- Fair play and respect for other players apply to item acquisition, use and exchange.
Who is affected
- Players who obtain, hold or exchange items are affected.
- Other players affected by item use or trading are affected.
- Game operators and community moderators are affected.
Owners Filled
Steward
The game operator maintains authoritative item rules and records, while players control permitted item actions within those rules.
Master systems
- The game's authoritative item definitions and inventory records govern item identity and possession.

- Does vr.tr.item specifically denote a bibliographic exemplar, as the INF.MED context suggests, or another sense of item?
- Which existing Vercy model, if any, already owns this concept and should be linked instead of duplicated?
- Which FRBR or IFLA LRM interpretation should govern item identity, especially for digital exemplars and replicas?
- How should bound-with materials, multipart exemplars and replacement components affect the continuity of item identity?
- Which institutional evidence and policies govern copy attribution, custody claims and access decisions?
