Where we need to use modeling language in Blockchain?
Permissions.acl file use which language? .cto file use which language? is it modeling language?
I know that logic.js file use the JavaScript language.
Please clear me about Modeling Language. Thanks in Advance.
From Wiki: https://en.wikipedia.org/wiki/Modeling_language
Modeling Language: A modeling language is any artificial language that can be used to express information or knowledge or systems in a structure that is defined by a consistent set of rules. The rules are used for interpretation of the meaning of components in the structure.
From Hyperledger Github: https://github.com/hyperledger/composer/blob/master/packages/composer-website/jekylldocs/reference/cto_language.md
The Hyperledger Composer modeling language is an object-oriented language which defines the business network model containing assets, participants, and transactions.
You can also see this tutorial. This tutorial will help to develop a project using Hyperledger Composer.
From The https://hyperledger.github.io/composer/latest/reference/cto_language
Hyperledger Composer includes an object-oriented modeling language that is used to define the domain model for a business network definition. A Hyperledger Composer CTO model file is composed of:
A single namespace. All resource declarations within the file are implicitly in this namespace.
A set of resource definitions, encompassing assets, transactions, participants, and events.
Optional import declarations that import resources from other namespaces.
And From the https://hyperledger.github.io/composer/latest/reference/acl_language.html Hyperledger Composer includes an access control language (ACL) that provides declarative access control over the elements of the domain model. By defining ACL rules you can determine which users/roles are permitted to create, read, update or delete elements in a business network's domain model.
