The ContentEngine is the foundation on which TopSoil is built.

Our engine borrows heavily from the concepts of the Git - Fast Version Control System.

To understand how Content Engine works, lets take an example in which Alex and Bob edit documents in the content engine. Lets say Alex creates a document named "ABC" in the content engine. Lets take the steps through which the Content Engine will go through

• Intially, Content Engine wont have any name "ABC" that live in the system.
• By creating the document "ABC", the system will add a name "ABC" in the engine and will point this to a vertex i.e. first version of this document.

ABC ---> ( doc1 )

• Now Alex edits the document and saves another version. At this stage, our system will add another vertex and will now point the name "ABC" to this newer version

(doc1) -> (doc2)

           ^
           |
          ABC

So, now ABC now points to doc2 i.e. the new version of the document.

• Now, another user Bob comes and they both start editing the document pointed to by name "ABC" and Bob creates a new version

(doc1) -> (doc2) -> (doc3)

                     ^
                     |
                    ABC

• Alice and Bob now decides that they have different views on topic "ABC" and they rather have their own versions of this topic. So, they the content engine looks like

                      -----> (doc5)  (doc2) -> (doc3) -> (doc4)  (doc5) -> (doc6)  (doc2) -> (doc3) -> (doc4) -----^

Consider the Content Engine as a graph where

Vertex = Particular version of a document Edge = Connecting different versions of documents Name = Name points to a vertex i.e. document
