Terms and Definitions

Term or Phrase	Abbreviation or Acronym	Definition
Authoritative Source		The system, database, or process that is designated as the definitive source of truth for a specific attribute or set of attributes in an inventory. When an inventory item’s attributes conflict across multiple sources, the authoritative source takes precedence.
Descriptive Attribute		An attribute of an inventory item that describes a property of the item itself — its name, type, status, version, owner, or other intrinsic characteristic. Descriptive attributes are managed within the inventory entry for the item.
Enterprise Inventory	EI	A managed collection of items of a defined type that the organization maintains in order to understand, govern, and make decisions about those items. Each enterprise inventory covers one category of enterprise asset, entity, or concept.
Enterprise Model	EM	The aggregate of all enterprise inventories and the relationships between their items. The Enterprise Model is not a single system — it is the unified intelligence layer formed by connecting well-maintained inventories into a coherent, queryable picture of the entire enterprise.
Federation		An approach to inventory management in which each organizational domain maintains its own inventory data under centralized governance standards, rather than requiring all data to be entered and managed in a single central system. Federation balances governance consistency with distributed ownership and local knowledge.
Inventory Coverage		A measure of how completely an inventory captures all items of its defined type that exist in the enterprise. An inventory with high coverage contains entries for all or nearly all items that should be in it. Low coverage means significant items are missing.
Inventory Currency		A measure of how current an inventory is — how recently its entries have been validated and updated to reflect the actual state of the items they represent. An inventory with high currency reflects the present state of the enterprise. Low currency means entries may be stale or outdated.
Inventory Accuracy		A measure of how correct the information in an inventory is — how well the attributes of inventory entries reflect the actual properties of the items they represent. An inventory with high accuracy contains reliable, trustworthy information.
Inventory Governance		The organizational framework of policies, roles, accountabilities, and processes that ensure inventories are properly owned, maintained, and aligned with enterprise standards. Inventory governance defines who has authority over inventory-related decisions and how those decisions are made.
Inventory Item		A single entry in an inventory representing one instance of the item type that inventory tracks. For example, a single application is one inventory item in the Systems and Applications Inventory.
Inventory Owner		The individual accountable for the overall governance, quality, currency, and maintenance of a specific inventory. The Inventory Owner is the authoritative point of contact for all questions and decisions related to their inventory.
Inventory Schema		The defined structure of an inventory — the set of attributes that every inventory item must or may have, the data types of those attributes, and the relationships between attributes. A well-defined schema ensures consistency across all items in the inventory.
Inventory Steward		The individual or team responsible for the day-to-day maintenance of an inventory — adding new items, updating existing items, validating accuracy, and flagging issues to the Inventory Owner. The Inventory Steward operates within the governance framework established by the Inventory Owner.
Relationship Attribute		An attribute of an inventory item that describes a relationship between that item and an item in another inventory. Relationship attributes connect inventories to each other and are the building blocks of the Enterprise Model.
Unique Identifier	UID	A stable, unique code or key assigned to every item in an inventory that unambiguously identifies that item across all systems and inventories. Unique identifiers enable cross-inventory relationships, impact analysis, and reliable data integration.
