GASP Framework Terms
ATL (Attribution Taxonomy Layer)
ATL (Attribution Taxonomy Layer): The tagging layer that classifies CEL events by lifecycle stage, expansion type and cost function. ATL is what enables dual-lens metrics (Operating form vs Market form).
Related Terms
Other definitions in GASP Framework Terms:
CEL (Commercial Event Ledger)
The atomic, immutable event layer from which all GASP metrics derive. Every metric in the standard traces back to CEL events. If an event is not in the CEL, it does not exist for metric purposes.
Adapter
The JSON mapping file that connects GASP's canonical field names to your warehouse columns. Each field declares its `schema.table.column` reference plus optional owners for the definition and the pipeline. The adapter is the only file a consuming organization writes.
Digital Twin
The combination of the GASP standard (metrics, relationships, ontology), your adapter (warehouse mapping) and an MCP server (agent access layer). Together they form a read-only semantic model of how a SaaS business operates. Agents read from the twin, not from source systems directly.
Ontology
The structured representation of GASP's entities, concepts, fields, source categories, temporal semantics and validation rules. The ontology sits below the metric layer and provides the canonical vocabulary that adapters, queries and agents reference.
Signal Type
A classification that describes what kind of signal a metric provides. Every GASP metric has exactly one primary signal type; some carry a secondary.
Sensitivity Tier
GASP's recommended data sensitivity classification for each metric. Aligns with ISO 27001 and OSSA `data_classification` conventions.
Access Scope
GASP's recommended filtering pattern for each metric. Describes whether the metric is naturally filterable by user context.
Change Nature
Optional CEL field that captures the intent behind a revenue movement. Does not alter metric calculations. Enables downstream analysis of revenue quality (e.g. Adjusted NRR).
Structured Formula
A decomposed representation of a metric's formula: explicit references to other metric nodes (with roles like numerator, denominator, addend) and the raw fields required. Enables agents to walk the dependency tree without parsing formula text.
Metric Owner
The named team or person responsible for a metric definition in an organization's adapter. Ownership is a required adapter field. When a metric value is disputed, the owner resolves the dispute. GASP provides the canonical definition; the owner decides whether their organization follows it or deviates, and documents the deviation.
Temporal Semantics
GASP's structured description of a metric's time grain, aggregation method and reporting frequency. Each metric has a mapping (e.g. MRR = End-of-month snapshot, Daily sync).
