35 -== 3. Annotations ==
27 +Sometimes external systems only talk in a specific character set. To ensure that all the data is properly communicated between eMagiz and the other system we need to make sure that we define which character set that is so we can tell it to eMagiz via a component. That way eMagiz will deviate from its default (i.e. UTF-8) and will process the file according to that different character set. In practice, we mainly see windows-1252 as an alternative that pops up once in a while. In various components that deal with file handling, you can define the character set on which eMagiz should act. Examples of such components are:

37 -In this microlearning, we will focus on using annotations on the flow level to clarify our thought process. In the annotation, you either describe a best practice everyone should follow when they change that flow (i.e. within the asynchronous routing) or describe how the (more complex) parts of the flow work. This will help yourself and others every time changes are needed within the flow.

39 -Annotations can be used for:
33 +In all these components you have the option to define the character set within the Advanced tab of the component. In this microlearning, we will use the File to string transformer to illustrate how that will look.

45 -To clarify the use cases let us take a look at how annotations can be added within the eMagiz platform. In our first example, we will take a look at asynchronous routing. In many eMagiz projects, a best practice is followed on how to add something to the asynchronous routing (or change something within the asynchronous routing). Because the best practice contains multiple steps it makes sense to use the annotation functionality of eMagiz to define all these steps and register them at the place you need them (i.e. the asynchronous routing). Having done so will result in something like this:
37 +In this field, you can define the character set of your choice. To make this work in eMagiz you need to navigate to the Create phase of eMagiz and open the entry flow in which you want to retrieve the file to a certain location. Within the context of this flow, we need to add functionality that will ensure that the correct character set is used. To do so first enter "Start Editing" mode on flow level. After that open, the File to string transformer, navigate to the Advanced tab, and fill in the correct character set. After you have defined the correct character set the only thing left to do is to Save the component. See the suggested additional readings section on the complete list of character sets that are supported by Java 8.

39 +Congratulations you have successfully learned how to specify the character set.

49 -The second example is about using annotations on the flow level to describe parts of the flow. In this example, we will use the annotation to describe that we use a filter to determine which messages are picked up from a local directory and how we filter. That way anyway opening the flow has to merely read the annotation to get the context. Having done so will result in something like this:

51 -<p align="center">[[image:novice-devops-perspectives-annotations--describe-parts-of-flow.png||]]</p>
52 -
53 -The third example does not take place on the flow level but the message definition level. Therefore instead of going to Create, we go to Design. In Design when you navigate to the CDM, API Gateway Data model, Event Streaming Data model, message definitions, etc. you have the option to add annotations to the canvas. In this example, we want to make clear to all that make changes that a certain part of our CDM is used by a lot of integrations within eMagiz and therefore everyone should be careful and think twice before adjusting anything related to that part. Having done so will result in something like this:

57 -Now that we saw some examples let us turn our attention to the how. How can I add an annotation and how can I link it. Adding the annotation is simple. You drag the annotation icon from the left context menu onto the canvas. As a result, an empty annotation will be shown on the canvas. By double-clicking on it you can type whatever you want. Note that you need to be in "Start Editing" mode to change anything, including annotations.

61 -When you are satisfied with what you have written down you can press the Save button. After you have done so you can rescale the annotation to ensure that the complete text is visible. To link the annotation to a component (on flow level) or an entity (on message definition level) you hover over the annotation until your mouse indicator changes to a + icon, execute a right-click and drag from the annotation to the component in question.
