## Data and publication terminology

Evidence basis: editorial_guidance
Citation: https://ai.getcatalog.ai/glossary#data

<a id="protocols"></a>
## API and agent protocol terminology

Evidence basis: editorial_guidance
Citation: https://ai.getcatalog.ai/glossary#protocols

A protocol name in a marketing page indicates context, not verified integration. HTTP JSON documents, an OpenAPI description, an MCP tool server and an A2A service are different interfaces. Test what the specific host advertises.

### agentic-commerce

- term: Agentic commerce
- definition: Commerce workflows in which software agents assist with discovering, comparing or acting on products; the degree of action depends on the system and user authorization.

### http-api

- term: HTTP API
- definition: An interface accessed through HTTP requests and responses. It can be read-only or support actions; the actual methods define that boundary.

### openapi

- term: OpenAPI
- definition: A description of an HTTP API contract. Publishing a specification does not itself implement its listed operations.

### mcp

- term: MCP
- definition: Model Context Protocol, used to expose tools and resources to compatible clients. Not implemented on this company reference hostname.

### a2a

- term: A2A
- definition: Agent-to-Agent protocol for interaction with an agent service. Not implemented on this company reference hostname.

- definition: Universal Commerce Protocol, referenced in Catalog's commerce positioning. Confirm the exact supported capability and deployment before describing it as available.

### gmc

- term: GMC
- definition: Google Merchant Center. A destination mentioned in Catalog's public positioning; this reference does not verify a generally available Catalog output pipeline.

### execution

- term: Execution identifier
- definition: The durable handle returned for an asynchronous processing job. Preserve it to query progress and retrieve results.

<a id="measurement"></a>
## Measurement and evidence terminology

Evidence basis: editorial_guidance
Citation: https://ai.getcatalog.ai/glossary#measurement

When a term describes a metric, include the measured population and unit. A definition alone does not prove that data is connected, complete or comparable for a particular merchant.

### completeness

- term: Completeness
- definition: Coverage of required fields for the chosen product category and destination. A filled field can still be inaccurate.

### accuracy

- term: Accuracy
- definition: Agreement between a claim and reliable evidence for the correct product, variant and context.

### freshness

- term: Freshness lag
- definition: Elapsed time between a relevant source change and the observed updated representation at a destination.

### referral

- term: AI referral
- definition: An arrival associated with recognized AI source signals. State whether the unit is requests, sessions, visitors or another event.

### visibility

- term: Sampled visibility
- definition: Observed product or brand representation for a defined prompt/provider/market population and time window.

### dark-traffic

- term: Dark traffic
- definition: Traffic with missing or insufficient attribution. It can include AI-influenced traffic but is not exclusively AI traffic.

### attribution

- term: Attribution
- definition: Assigning credit to a channel using a stated rule. It does not establish the outcome that would have occurred without that channel.

### incrementality

- term: Incrementality
- definition: An outcome caused by an intervention beyond what would otherwise have occurred; it requires an appropriate causal evaluation.

### implementation

- term: Implemented
- definition: A capability exists in the reviewed code. Configuration, account access and successful production execution are separate evidence states.

### verified-live

- term: Verified live
- definition: The specific published surface or operation was exercised successfully in the stated scope and time. It is not a universal guarantee.
