** Version: 0.1\ Status:** Draft (Conceptual)
This specification defines how a GEOS-certified Data Pipeline relates to one or more GEOS Outcome Signal Portfolios (GeOSP), without creating coupling or dependency violations.\ It clarifies the interface between Data Pipelines and GeOSPs while preserving strict separation of concerns.
This document applies to:
Any Data Pipeline seeking or holding GEOS certification.
The interaction boundary between a certified Data Pipeline and downstream GeOS Outcome Signal Portfolios.
This document does not define:
Outcome Signal Portfolio structure or rules.
How funders select, weight, or interpret outcome signals.
Any certification criteria for GeOSPs themselves.
A GEOS-certified Data Pipeline:
Produces standardized output artifacts at its Exit boundary.
Declares the standards, schemas, and signal families that its outputs are compatible with.
Makes no assertions about how, whether, or by whom those outputs are used downstream.
A GeOSP:
May declare dependency on one or more certified Data Pipelines.
Selects, combines, or transforms pipeline outputs according to GeOS-defined portfolio rules.
Bears responsibility for portfolio-level logic, interpretation, and finance relevance.
*Canonical rule applies:* Artifacts must declare their dependencies, never their dependents.
A GEOS-certified Data Pipeline MAY declare:
Which GEOS signal families its outputs are compatible with.
Which GEOS-defined output schemas and semantic contracts it satisfies.
The versions of GEOS standards under which compatibility is asserted.
A GEOS-certified Data Pipeline MUST NOT:
Declare which GeOSPs use, rely on, or incorporate its outputs.
Encode assumptions about portfolio composition, weighting, or selection.
Require knowledge of downstream aggregation or finance logic.
The interface between a Data Pipeline and a GeOSP is defined entirely by:
The pipeline's certified Exit artifacts (per GEOS-DP-005.
The pipeline's declared compatibility metadata.
The GeOSP's independent declaration of dependency on those artifacts.
No bidirectional linkage is permitted.
During certification or re-assessment:
Auditors evaluate whether pipeline outputs conform to declared compatibility claims.
Auditors do not assess actual downstream usage by any GeOSP.
Misalignment between a pipeline's declared compatibility and a GeOSP's dependency claims is resolved at the GeOSP level, not by modifying the pipeline.
This structure:
Preserves modularity across the GEOS standards stack.
Prevents circular dependencies between artifacts.
Allows Data Pipelines to remain stable as new GeOSPs are introduced or retired.
Mirrors separation practices in health and financial standards systems.
This specification does not require a Data Pipeline to:
Track downstream adoption.
Embed portfolio identifiers.
Change certification status based on portfolio usage.
