Name	English / stable code	Where it appears	When you use it
External resource	external resource	Data and Ontology → Resource Access	Registering SAP, semantic-model, knowledge, or database sources
Resource	Resource / `resourceId`	Resource list and details	Maintaining connection, owner, version, and capabilities
Resource type	Resource Type / `resourceType`	Register External Resource form	Selecting an adapter such as `semantic_model`, `sap_odata_api`, `knowledge`, or `database`
Connection reference	`connectionRef`	Resource form and Secrets	Binding a resource to a Secret version
Capabilities	capabilities	Resource form and Settings	Restricting sync scope, query endpoints, and execution boundaries
Sync job	Sync Job	Resource details → Sync Jobs	Running full or incremental syncs, retries, cancellation, or cleanup
Ontology snapshot	Ontology Snapshot / `snapshotId`	Ontology Workspace and Audit	Fixing one published view of entities, relationships, and actions
Graph version	Graph Version / `graphVersion`	Ontology Workspace and entity graphs	Reproducing graph queries and Assistant context
Ontology definition	Ontology Definition	Ontology Studio	Designing entity types, relationships, actions, and versions
Runtime projection	Runtime Projection	Ontology Workspace health	Turning a published snapshot into searchable entities and relationships
Entity	Entity	Entity search and graphs	Locating a business object by type, name, or external key
Relation	Relation	Entity graphs	Inspecting direction, endpoints, and properties between objects
Action	Action / `actionTypeCode`	Agent Tools and resource chat	Discovering, simulating, and executing an object capability
Discovery mode	discovery mode	Action contract	Deciding whether an action can be planned automatically or must be triggered manually
Policy binding	Policy Binding	Governance → Policies	Returning allow, deny, or require approval for a resource, entity type, or action
Approval request	Approval Request / `approvalRequestId`	Governance → Approvals	Getting human approval for a high-risk action
Execution audit	Execution Audit / `taskId`, `traceId`	Governance → Execution Audit	Reviewing caller, policy, snapshot, evidence, and result
Semantic-model resource	`semantic_model`	Resource types and Data & Analytics	Querying and syncing an existing BI or OLAP model
Business ontology resource	`business_ontology`	Ontology Studio and plugins	Defining cross-resource domain semantics and governance contracts
Adapter	Adapter	Resource type catalog	Mapping an external protocol to the canonical IR and actions
Canonical ontology IR	Canonical Ontology IR	Sync logs and architecture	Unifying adapter output before snapshot publication
Ontology Assistant	Ontology Assistant	Ontology Workspace and resource chat	Explaining semantics using the current resource and snapshot
ChatKit	ChatKit	Agent Workbench and resource chat	Triggering Agent Tools and visualized results through conversation

Stable codes are used by APIs, plugins, and audits. Display names can be localized, but integrations must continue to use the stable codes.
