If you reduced your b2b exchanges to the simplest schema, what would they look like? For example a response to a bid could look like this:
```
{
item_id: int
bid: int // USD
size: enum // { S, M, L, XL }
}
```
Emphasis on the word "data", as in not your natural language communications, unless there's the possibility to describe them in such a structured way.
