| The proposed architecture involves the creation of two megaservices. | ||
| - The first megaservice functions as the core pipeline, comprising four microservices: embedding, retriever, reranking, and LVLM. This megaservice exposes a MMRagBasedVisualQnAGateway, allowing users to query the system via the `/v1/mmrag_visual_qna` endpoint. | ||
| - The second megaservice manages user data storage in VectorStore and is composed of a single microservice, embedding. This megaservice provides a MMRagDataIngestionGateway, enabling user access through the `/v1/mmrag_data_ingestion` endpoint. |

Can this be an enhanced microservice based on the existing data ingestion?

@hshen14 Thanks for your comments. The simple answer is yes. We will enhance/reuse the existing data ingestion microservice. Current data ingestion microservice supports only TextDoc. In our proposal, we will enhance its interface to accept MultimodalDoc which can be either TextDoc, ImageDoc, ImageTextPairDoc, etc... If the input is of type TextDoc, we will divert the execution to current microservice/functions.

This megaservice is composed of 2 microservices: transcripting and LVLM. This megaservice provides a MMRagVideoprepGateway, enabling user access through the `/v1/mmrag_video_prep` endpoint. |

You mentioned either audio-to-text models for transcripting or LVLM model for captioning, while you also mentioned they need to be composed. If composing is not mandatory, does it make sense to make it as microservice?

@hshen14 Thanks for your comment. We were proposing each transcripting and LVLM being a microservice. The composition is not mandatory. We believe that when we ingest a video, it is better to include both frames' transcripts and frames' captions as metadata for inference (LVLM) after retrieval. However, in the megaservice we will have different options for user to choose whether they want transcript only, caption only or both. The composition here is optional. Hope this is clear to you.

The overall RFC is good to me. just minor comment here. I think this interface is implementation specific one, right?. my point here is you don't need to mention that. you just need tell user what's the standard input and output just like you did in Data Classes section, that's enough.

The RFC file naming convention follows this rule: yy-mm-dd-[OPEA Project Name]-[index]-title.md
For example, 24-04-29-GenAIExamples-001-Using_MicroService_to_implement_ChatQnA.md

We submit our RFC for Multimodal-RAG based Visual QnA.
@ftian1 @hshen14: Could you please help to provide feedbacks?
