ArcXA Evidence Layer; high-fidelity execution and semantic layer

ArcXA as the "Evidence Layer,"  addresses the "broader problem" of data governance and lineage.

Evidence Layer (EL), provides the connective tissue— to assist in Post Migration Issue Resolution (OMIR)

Answering the  "how" and "why" of every byte changed, for platforms like Collibra, Informatica, Atlan, and IBM InfoSphere (InfoStream) which focus on governance, discovery, and enterprise ETL.

ArcXA acts as the high-fidelity execution and semantic layer that bridges the gap between static metadata catalogs and active data movement.

The ArcXA Integrated Data Map

ArcXA integrates into an ecosystem featuring these major players:

1. Governance & Discovery (Collibra & Atlan)

ArcXA serves as the Active Metadata Provider for these platforms.

• The Integration: ArcXA feeds its graph-native lineage and ontology-aware mappings directly into Collibra or Atlan.

• The Value: Instead of Collibra just showing a table exists, ArcXA tells it exactly which policy was active during the last transformation and which semantic normalization was applied. It turns a static catalog into a living map of validated data.

2. Enterprise Integration & ETL (Informatica)

ArcXA acts as the Validation & Semantic Wrapper.

• The Integration: While Informatica moves massive volumes of data, ArcXA sits on top of the workflow orchestration to provide systems-of-systems validation.

• The Value: ArcXA tracks the "why" behind Informatica's movements. If Informatica moves data from a CRM to a Warehouse, ArcXA ensures the ontology terms stay consistent and the contract-aware policies are met before the data lands.

3. Legacy & Quality (IBM InfoSphere / InfoStream)

ArcXA functions as the Modern Interop Layer.

• The Integration: ArcXA can ingest "capability reporting" from InfoSphere’s QualityStage or Information Analyzer.

• The Value: It translates IBM’s deep technical lineage into ArcXA’s unified multi-source normalization. This allows downstream modern apps to consume legacy IBM data without needing to understand IBM's internal schemas.

Conceptual Integration Architecture

Component	Role in Ecosystem	ArcXA Synergy
Collibra / Atlan	Policy & Cataloging	ArcXA provides execution-level lineage to prove policies were actually followed.
Informatica	Heavy-lift Data Movement	ArcXA provides semantic mapping and validation to ensure movement matches the ontology.
IBM InfoSphere	Quality & Master Data	ArcXA creates unified catalogue views across legacy and modern data silos.
Downstream Apps	Consumption	ArcXA provides the confidence report (the "why" and "what changed").

ArcXA Flow: From Source to Downstream

1. Onboarding: ArcXA reports the connector capabilities of your Informatica or IBM sources.

2. Semantic Layer: It maps those sources to a unified ontology (sharing this metadata with Atlan).

3. Execution: As workflows run, ArcXA tracks row and graph-native lineage, recording which contract was active.

4. Verification: Before the data hits a downstream BI tool, ArcXA validates the system-of-systems map, ensuring no breaks in the chain.
