Abstract

Gateway Domain-Centric Routing (GDCR) – Version 5. 0A Vendor-Agnostic Metadata-Driven Architecture for Enterprise API GovernanceJavaScript “Maverick Ghost” Reference Implementation v15. 1 ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ This paper introduces Gateway Domain-Centric Routing (GDCR), a vendor-agnostic architectural framework designed to structurally reduce API and integration sprawl by routing requests through business semantics rather than system-specific proxies. Instead of multiplying gateways and packages per backend, GDCR uses a metadata-driven control plane to route traffic by domain, entity, and action (e. g. , /sales/orders/create). Version 5. 0 consolidates the model with a validated SAP BTP reference implementation combining DCRP (gateway) and PDCP (orchestration), achieving up to 90% structural reduction while preserving performance, security, and vendor flexibility. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ WHAT WAS VALIDATED — GDCR v5. 0 (Sandbox the author assumes no liability for usage. Evolution to v15. 1 — The Maverick Ghost Edition All validation milestones above were executed using JavaScript v14. 2 as baseline. Version v15. 1 (Maverick Ghost) introduces algorithmic optimizations (binary search O (log n), zero-allocation string handling, strict normalization rules) that further reduce routing latency and improve determinism. These improvements do not change the architectural conclusions, but reinforce that GDCR’s control-plane model scales without becoming a performance bottleneck. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ RELATED WORK Blog Posts: • Medium: Gateway Domain-Centric Routing https: //medium. com/@rhviana/gateway-domain-centric-routing-a-vendor-agnostic-api-architecture-52ad30d1d1d9 Code: GitHub repo under construction: https: //github. com/rhviana/gdcp - Under Construction release date 27/02 ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ ALTERNATIVE NAMES (FOR SEARCH/DISCOVERY) GDCR has been called by different names in different contexts: • DCRP (Domain-Centric Routing Pattern) • MDAGR (Metadata-Driven API Gateway Routing) • DOAGA (Domain-Oriented API Gateway Architecture) • APSRA (Anti-Proxy-Sprawl Routing Architecture) • Informal: "The Viana Pattern", "Commander's Brain", "Maverick Ghost" Pick whichever resonates with your architecture style. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ CONTACT Ricardo Luz Holanda Viana Independent Researcher & SAP Integration Architect 📧rhviana@gmail. com LinkedIn: https: //www. linkedin. com/in/ricardo-viana-br1984/ Medium: @rhviana Questions, feedback, and collaboration inquiries welcome. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ LICENSE & TRADEMARK License: CC BY 4. 0 (share, adapt, commercial use OK with attribution) Trademark: Maverick Engine™ is a trademarked component of GDCR. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ ACKNOWLEDGMENTS Thanks to the SAP Community for feedback on DCRP/PDCP, and to the architects who validated this in real sandboxes.
