See Table 8 on page .
A list of terms form a sentence. Every sentence is generated by only one dagent but, depending on the connections in the conversation, may be consumed by many dagents. The sentence enters the conversation from one connection and leaves the conversation at another connection.
In the conversation the sentence is atomic. The sentence is either all present or not present at all. A sentence cannot be interrupted preventing the overlapping of two sentences.
Every sentence has an identifier.
