Business network archive

Composer business is comprised of four different types of files: model file (.cto), script file (.js), access control list (ACL) file (.acl), and query file (.qry).

Network model file (.cto)

A CTO file is composed of the following elements:

Element	Description
A single namespace	Defines the composer model namespace; every .cto model file requires a namespace.
Resources - asset	Anything of value that can be exchanged between parties.
Resources - participant	Business network member.
Resources - enum	A data type consisting of a set of named values.
Resources - concept	Any object you want to model that is not one of the other types.
Resources - transactions	Defines the blockchain business logic.
Resources - events	Blockchain transaction notification.
Import	Imports resources from other namespaces.

 

The composer model language, like other programming languages, has data types including String, Double, Integer, and so on.
