PowerGraph Semantic Control Plane (SCP)

 

Equitus and its ArcXA platform function as a Semantic Control Plane (SCP), leveraging an ISV relationship with IBM (specifically centered on IBM Power10 hardware and Knowledge Graph Neural Networks / KGNN architectures) to re-engineer cross-system migrations.

By embedding a Triple Store model (Subject – Predicate – Object), ArcXA elevates data migrations out of rigid ETL scripts and into a semantically-governed metadata overlay.

Key Architectural Pillars

1. Hardware & Runtime Alignment (IBM Power Systems)

• On-Premise Inferences: ArcXA and Equitus KGNN are optimized for IBM Power10 hardware, exploiting its Matrix Math Accelerator (MMA) engines. This allows localized graph calculations, vector embedding matching, and semantic reasoning directly on enterprise data cores (z/OS mainframes or Power Systems) without sending data to public clouds.

• High-Throughput Local Graph Sharding: Utilizing native arcxa-shard RDF/SPARQL runtimes, ArcXA scales triple store lookups across distributed memory spaces, enabling real-time validation during massive legacy-to-cloud transfers.

2. The Semantic Control Plane (SCP)

Traditional migration tools move rows from Source Table A to Target Table B using static schema mappings. As an SCP, ArcXA sits above existing ETL pipelines:

• Decoupled Execution: ETL handles heavy lifting/data transport, while ArcXA governs intent, context, and schema lineage.

• Policy-Driven Validation: Ensures cross-system consistency by executing constraints against the active ontology, blocking invalid transformations before target persistence occurs.

3. Enhancing Migrations via Triple Stores (S – P – O)

Instead of flattening complex relationships into relational tables, data entities and mappings are stored as knowledge graph triples:

{Subject (Source Entity)}--->{Predicate (Semantic Relationship)}} {Object (Target / Standard Ontology)}

• Contextual Mapping: A legacy IBM mainframe field CUST_LST_NM is mapped via triples:

  (S) [db2:CUST_LST_NM] -> (P) [owl:sameAs] -> (O) [core:CustomerLastName]

• Lossless Schema Evolution: When moving from a mainframe COBOL copybook/DB2 schema to a modern cloud database, field definitions, dependencies, and business meanings are preserved regardless of structural differences.
