** Version: 0.1\ Status:** Draft (Proposed)
1. Purpose ————--
This specification defines the mandatory artifacts produced when a Data Pipeline is certified under GEOS, and the schema by which those artifacts are recorded and discoverable in a GEOS-recognized registry.
The purpose is to enable repeatable reliance, audit, and reference to certified Data Pipelines without disclosing operational data or introducing coupling to downstream artifacts.
2. Scope ————
This specification applies exclusively to:
Artifacts created as a result of Data Pipeline certification
The minimal registry metadata required to reference those artifacts
It does not define:
Registry governance or hosting
Access control mechanisms
Funding, policy, or operational decisions
3. Certification Artifacts ——————————
Upon successful certification, the following artifacts MUST exist.
A formal declaration that a specific Data Pipeline conforms to applicable GEOS-DP standards.
The certificate MUST include:
Pipeline Identifier (globally unique)
Certified Specification Version(s)
Certification Date
Certification Validity Period
Conformity Assessment Reference
Pipeline Version Identifier
Hash or immutable reference to the certified configuration
The certificate asserts conformity only; it makes no claims about effectiveness, impact, or funding eligibility.
A machine- and human-readable description of what was certified.
The scope statement MUST specify:
Entry boundary covered by certification
Exit boundary covered by certification
Processing stages included
Explicit exclusions (if any)
This artifact constrains interpretation of the certificate and prevents overextension of claims.
A structured declaration affirming that the certified pipeline satisfies GEOS-DP traceability requirements.
It MUST reference:
Applicable traceability standard(s)
Methods used to establish lineage integrity
Evidence references examined during assessment
A structured declaration affirming that integrity and tamper-resistance requirements were assessed.
It MUST specify:
Integrity controls evaluated
Versioning and immutability mechanisms relied upon
Limitations or assumptions, if any
A minimal, non-sensitive summary suitable for public discovery.
It MUST include:
Pipeline Identifier
Certification Status
Validity Period
High-level description of pipeline purpose
It MUST exclude operational details, data content, and confidential metadata.
4. Registry Schema (Minimal) ——————————--
A GEOS-recognized registry MUST support, at minimum, the following fields for each certified Data Pipeline:
Field Description ———————-- ————————————————— Pipeline ID Unique identifier for the certified Data Pipeline Pipeline Version Version of the pipeline configuration certified Certification Status Active, expired, suspended, or withdrawn Certification Date Date of certification decision Valid Until End of certification validity Certified Specs List of GEOS-DP specs satisfied Scope Reference Link or hash to Certification Scope Statement Certificate Reference Link or hash to Data Pipeline Certificate Public Summary Link to Certification Summary
The registry records certification artifacts; it does not execute logic or enforce behavior.
5. Dependency Declaration —————————--
Certification artifacts MAY declare:
Which GEOS-DP specifications they depend upon
Which versions of those specifications were applied
Certification artifacts MUST NOT declare:
Which Outcome Signal Portfolios consume the pipeline
Which downstream artifacts rely on the pipeline
This enforces the Canon rule: artifacts declare dependencies, never dependents.
6. Versioning of Certification Artifacts ——————————————--
Each certification artifact MUST be versioned independently.
A change to:
Pipeline configuration
Applicable specification version
Integrity or traceability mechanism
REQUIRES issuance of a new certification artifact set.
Historical artifacts MUST remain accessible for audit and longitudinal comparison.
7. Withdrawal and Supersession ———————————-
If certification is withdrawn or superseded:
The registry status MUST be updated
Prior artifacts MUST remain immutable
A withdrawal or supersession notice MUST be issued
Withdrawal does not imply fault unless explicitly stated.
8. Non-Requirements ———————--
This specification does not require:
Public disclosure of pipeline internals
Real-time registry updates
Any particular registry technology
Any coupling to funding mechanisms
