DCEP — Domain-Centric Event Pattern: Semantic Topology Governance for Non-Orchestration Runtime Fabrics

📌Author Note The concepts, architectural models, governance principles, and naming structures presented in this work were conceived and developed by Ricardo Luz Holanda Viana — March 2026.

All substantive ideas, technical decisions, and final validation remain the sole responsibility of the author. ⚠️ Reading Order — Start with GDCR. GDCR (DOI: 10. 5281/zenodo. 18582492) is the foundation of the entire ecosystem. Begin there — every other layer (DDCR, ODCP, SDIA, DEIP) builds on top of it. Without GDCR, the full picture will be incomplete. DCEP (Domain-Centric Event Pattern) is a formal, vendor-agnostic semantic topology governance specification for non-orchestration runtime fabrics within the SDIA (Semantic Domain Integration Architecture) ecosystem. DCEP establishes domain-as-primary-key as a normative governance principle for event brokers, message queues, event meshes, IoT fabrics, service meshes, and edge runtimes — extending semantic continuity across the full SDIA architectural stack below the orchestration layer (ODCP). This specification defines: - Formal ABNF naming grammars for all runtime fabric types - Post-Validation Rule Layer (PVRL) with normative regex constraints - DCEP–DDCR formal activation boundary and resolution algorithm - Domain Authority governance lifecycle (8 stages) - Security threat model with namespace hijacking countermeasures - OpenTelemetry observability propagation model - Cross-fabric conformance checklist (18 criteria) Related prior art: USPTO TM 99680660 / 99691792 SDIA Ecosystem DOI: 10. 5281/zenodo. 18582492 Keywords: semantic topology governance, domain-centric architecture, event-driven integration, enterprise integration patterns, Kafka governance, IoT domain routing, service mesh governance, SDIA, DDCR, distributed systems Companion Architectures: Gateway Domain-Centric Routing (GDCR) — DOI: https: //doi. org/10. 5281/zenodo. 18582492 Domain Driven Centric Router (DDCR) — DOI: https: //doi. org/10. 5281/zenodo. 18864832 Orchestration Domain-Centric Pattern (ODCP) — DOI: https: //doi. org/10. 5281/zenodo. 18876593 Semantic Domain Integration Architecture (SDIA) — DOI: https: //doi. org/10. 5281/zenodo. 18864832 Domain Enterprise Integration Pattern — DOI: https: //doi. org/10. 5281/zenodo. 18876593 License: Creative Commons Attribution 4. 0 International (CC BY 4. 0) ORCID: https: //orcid. org/0009-0009-9549-5862 Citation — APA: Viana, R.
