Portal Architecture

مكونات المنصة

The portal is organized into clear layers that support the browse/search experience, content governance and releases, developer enablement, and security/audit— ensuring transparency, scalability, and easy consumption of national assets (Data Elements / Value Sets / Mappings).

تتكون المنصة من طبقات واضحة تدعم تجربة المستخدم والحوكمة وتمكين المطورين ومتطلبات الأمن والتدقيق.

SoT: Source of Truth Lineage: Generated In Impact: Where Used / Consumers Analytics: OMOP CDM Interoperability: FHIR / NPHIES Outputs: API / Export
Generated In HIS / Operational Systems Point of capture Hub Data Elements / Value Sets / Mappings SoT + Versioning + Change Log Where Used (Consumers) + Impact API / Exports SoT Authoritative custodian Consumers NHO / Data Bank / BI OMOP Analytics via CDM
Experience layer
  • Bilingual search and browse (AR/EN)
  • Artifact pages showing SoT, Generated In, Where Used, and mappings (FHIR/NPHIES/OMOP)
  • Change impact view: deprecation/replacement and consumer impact
Content & governance layer
  • Structured repositories: Domains, Data Elements, Value Sets, Code Systems, Mappings
  • Review/approval workflow (Change Requests) with decision log and comments
  • Releases + effective dates + deprecation/replacement tracking
Developer enablement layer
  • REST APIs (search/retrieve/releases/exports)
  • CSV/JSON exports + release artifacts
  • Implementation aids: FHIR JSON viewer + mapping transform examples
Security & audit
  • RBAC for content administration with clear separation of duties
  • Access-tier segmentation (Public / Restricted)
  • Comprehensive audit trail for changes, mappings, and releases
Important note
The portal does not create new national registries; it standardizes publishing and strengthens transparency (SoT/Lineage/Impact), enabling interoperability and analytics through governed mappings.
