# Introduction

In the representation section we saw how to use [`BaseDoc`][docarray.base_doc.doc.BaseDoc], [`DocList`][docarray.array.doc_list.doc_list.DocList] and [`DocVec`][docarray.array.doc_vec.doc_vec.DocVec]
to represent multimodal data. In this section we will see **how to send such data over the wire**.

This section is divided into two parts:

- [Serializing](./serialization.md) [`BaseDoc`][docarray.base_doc.doc.BaseDoc], [`DocList`][docarray.array.doc_list.doc_list.DocList] and [`DocVec`][docarray.array.doc_vec.doc_vec.DocVec]
- [Using DocArray with a web framework to build a multimodal API](./api/jina.md)
