Multimodal RAG Platform

Architecture Views

16 views. Every view ships three ways: as this HTML page, as SVG that re-opens in diagrams.net fully editable, and as draw.io source.

01 System ContextC4 Level 1. Who uses the platform, which content sources feed it, and which external services it depends on. HTML · SVG · draw.io 02 High-Level ArchitectureThe whole platform in six stages: ingest, understand, index, retrieve, generate, serve. The picture a sponsor should understand without narration. HTML · SVG · draw.io 03 Layered ArchitectureSix layers with dependencies pointing downward only. Establishes what may call what. HTML · SVG · draw.io 04 Container ArchitectureC4 Level 2. Deployable units, their technology, and the synchronous query path between them. HTML · SVG · draw.io 05 Multimodal Ingestion PipelineOne lane per modality across five stages. The lanes run in parallel and converge on a single chunk record. HTML · SVG · draw.io 06 Indexing & Embedding PipelineHow a normalised chunk becomes a retrievable, governed index entry. HTML · SVG · draw.io 07 Retrieval & Generation FlowThe query path from admitted question to verified, cited answer. HTML · SVG · draw.io 08 Data ArchitectureFour zones by ownership and rebuildability. Only one of them is irreplaceable. HTML · SVG · draw.io 09 Integration ArchitectureEvery inbound and outbound interface, with protocol, cadence and direction. HTML · SVG · draw.io 10 Security ArchitectureFive trust zones in decreasing exposure, with every boundary crossing labelled — including the attacker's path. HTML · SVG · draw.io 11 Deployment & InfrastructureWhat runs where, across two availability zones and a warm standby region. HTML · SVG · draw.io 12 CI/CD & Environment PromotionHow a change reaches production, and what stops a bad one — including a bad prompt. HTML · SVG · draw.io 13 Observability & Evaluation MatrixSix signal types across five stages. A matrix rather than a flow, because it makes the gaps visible. HTML · SVG · draw.io 14 RAGOps LifecycleThe improvement loop, drawn as a loop. A RAG system is never finished at launch. HTML · SVG · draw.io 15 Critical Flow — Question to Cited AnswerThe end-to-end request as ordered messages across eight participants, including the abstain path. HTML · SVG · draw.io 16 Core Data ModelNine entities carrying multi-tenancy, multimodal provenance and citation lineage. HTML · SVG · draw.io
