Ubiquitous Language

What Is It

Essentially it is the language used by everyone in a project from stakeholders down to engineering to improve communication and reduce misunderstandings.

So…how / why does it apply here

One thing I have noted is that I have tended to chop and change the terms I use through documentation and code which is bound to make things confusing. Whilst I completely understand what is used where and when, this doesn’t make it any easier for someone trying to implement this framework in an application. I need to be more consistent through code and through documentation to make sure everyone is clear how it works.

Definitions

Kyameru

Kyameru is the name of the framework.

Route

Route is the name of what you create to take a message from a starting point to its eventual end point. A Route consists of Components, chains and a Routable message.

Component

A Component is what you pull in to use as part of your Route. A component may be something like S3 or SQS.

Chain Link

A Chain Link refers to the implementation of the From or To parts of a component. So a component contains Chain Links that in turn are consumed by Chains in the core library.

Chain

A Chain is the fundemental implementation of the Chain Of Responsibility pattern. Each chain passes execution through to the next (depending on your Route setup) until the last in the chain.

Processor

A Processor refers to any object or class acting directly on a Routable message. Even though the Process part of the a Route is executed in a chain, because it is optional it is more of a processor than a Chain Link.

Routable

The Routable is the data passed from one Chain to another. This data is updated as it goes through each Chain and Processor.
