What is Business Network CTO Modeling Language?
✍: FYIcenter.com
Business Network CTO Modeling Language is a special data modeling language to define complex data types from primitive data types.
CTO source code can be stored in a single or multiple files with the *.cto file extension.
Each CTO source code file should have the following structure.
"namespace" statement - required "import" statements - optional Resources declaration statements - optional "participant" declaration statements "asset" declaration statements "transaction" declaration statements "event" declaration statements "concept" declaration statements "enum" declaration statements
Here is an example of a CTO file, models/model.cto:
/* Copyright (c) FYIcenter.com */ namespace com.fyicenter.hyperledger import com.fyicenter.common participant Customer identified by customerId { o String customerId o String firstName o String lastName --> Address address } asset Car identified by vin { o String vin o String maker o String model o Double value o Currency currency --> Customer owner } transaction Trasfer { --> Car car --> Customer newOwner } event CarOwnerChanged { --> Car car --> Customer newOwner --> Customer oldOwner } concept Address { o String street o String city o String state } enum Currency { o USD o CAN o EUR }
