Multimodal RAG Platform
A platform that ingests text, PDFs, images, tables, audio and video, and answers natural-language questions across all of it with grounded, cited responses.
16 views, each in three formats.
Open a view to read it in full. Every SVG carries its diagram source inside it, so it opens in diagrams.net fully editable with no import step; the draw.io files are the same diagrams as plain source.
-
01
System Context
C4 Level 1. Who uses the platform, which content sources feed it, and which external services it depends on.
-
02
High-Level Architecture
The whole platform in six stages: ingest, understand, index, retrieve, generate, serve. The picture a sponsor should understand without narration.
-
03
Layered Architecture
Six layers with dependencies pointing downward only. Establishes what may call what.
-
04
Container Architecture
C4 Level 2. Deployable units, their technology, and the synchronous query path between them.
-
05
Multimodal Ingestion Pipeline
One lane per modality across five stages. The lanes run in parallel and converge on a single chunk record.
-
06
Indexing & Embedding Pipeline
How a normalised chunk becomes a retrievable, governed index entry.
-
07
Retrieval & Generation Flow
The query path from admitted question to verified, cited answer.
-
08
Data Architecture
Four zones by ownership and rebuildability. Only one of them is irreplaceable.
-
09
Integration Architecture
Every inbound and outbound interface, with protocol, cadence and direction.
-
10
Security Architecture
Five trust zones in decreasing exposure, with every boundary crossing labelled — including the attacker's path.
-
11
Deployment & Infrastructure
What runs where, across two availability zones and a warm standby region.
-
12
CI/CD & Environment Promotion
How a change reaches production, and what stops a bad one — including a bad prompt.
-
13
Observability & Evaluation Matrix
Six signal types across five stages. A matrix rather than a flow, because it makes the gaps visible.
-
14
RAGOps Lifecycle
The improvement loop, drawn as a loop. A RAG system is never finished at launch.
-
15
Critical Flow — Question to Cited Answer
The end-to-end request as ordered messages across eight participants, including the abstain path.
-
16
Core Data Model
Nine entities carrying multi-tenancy, multimodal provenance and citation lineage.
Everything as it was delivered.
These files are served exactly as they were produced — the diagram pages keep their own house style because that is the artifact, not a rendering of it.
