In the annotation, you either describe a best practice everyone should follow when they change that flow (i.e. within the asynchronous routing), describe how the (more complex) parts of the flow work or describe (parts of) of your message definitions (i.e. CDM, API Gateway Data model, system message, etc.). This will help yourself and others every time changes are needed.

6 6  == 1. Prerequisites ==
12 +
7 7  * Basic knowledge of the eMagiz platform
8 8  
9 9  == 2. Key concepts ==
10 -This microlearning centers around the endpoint check.
11 11  
12 -By endpoint check, we mean: determine whether the WSDL is accessible on the correct endpoint so we can forward the URL to the WSDL + the URL to call to our external parties
17 +This microlearning centers around using annotations.
18 +With annotations, we mean: A piece of text to explain something to yourself and others
13 13  
14 -* The endpoint consists of the following elements:
15 - ** Starts with https:// or http://
16 - ** Second part is the host (i.e. where is the endpoint running)
17 - ** Third part is the port on which the incoming traffic is accepted
18 - ** These three things combined make up the first part of our endpoint that will vary per environment
19 - ** Following that we have a static remainder of the endpoint that is build up as follows: /{soap WS name}/{Id}/
20 - ** If you want to get to the WSDL simply add the name of the WSDL (which is defined by the Id given to the "Dynamic WSDL" support object) and the .wsdl extension to the endpoint when viewing it in the browser
20 +Annotations can be used for:
21 21  
22 -== 3. Endpoint Check ==
22 +* Describing a best practice everyone should follow
23 +* Describing (more complex) parts of the flow
24 +* Describe (parts of) your message definitions
23 23  
24 -When setting up a point where your customers can talk to you, eMagiz offers various methods for creating such a point. One option is hosting a SOAP Webservice in eMagiz that handles XML messages asynchronously or synchronously. One last check to perform before you can communicate with the external parties that the endpoint is available to receive messages and is up and running. In this microlearning, we will learn how you can perform such a check.
25 25  
26 -* The endpoint consists of the following elements:
27 - ** Starts with https:// or http://
28 - ** The second part is the host (i.e., where the endpoint is running)
29 - ** The third part is the port on which the incoming traffic is accepted
30 - ** These three things combined make up the first part of our endpoint, which will vary per environment
31 - ** Following that, we have a static remainder of the endpoint that is built up as follows: /{soap WS name}/{Id}/
32 - ** If you want to get to the WSDL, add the name of the WSDL (which is defined by the ID given to the "Dynamic WSDL" support object) and the .wsdl extension to the endpoint when viewing it in the browser
33 33  
34 -As you can see, the endpoint can be divided into two parts. One part is dynamic across environments, and one part is static across environments. Let us first determine how to find the first part of our endpoint.
28 +== 3. Annotations ==
35 35  
36 -=== 3.1 HTTPS or HTTP ===
30 +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.
37 37  
38 -We start at the top with the determination of HTTPS or HTTP. A simple rule of thumb is that when running in the eMagiz Cloud, the endpoint starts with https://, and when running locally (i.e., on-premise), the endpoint starts with http:// (unless you secure it yourself; more on that later).
32 +Annotations can be used for:
39 39  
40 -=== 3.2 Host ===
34 +* Describing a best practice everyone should follow
35 +* Describing (more complex) parts of the flow
36 +* Describe (parts of) your message definitions
41 41  
42 -The next part of the endpoint is the host. The host is the (virtual) machine on which the endpoint runs. When hosting an endpoint in the eMagiz cloud, the host part is the combination of the DNS left-most label on the Route level and the cloud slot on which your environment is running. The first part of the equation can be found under Deploy -> Architecture. The second part can be found under Deploy -> Properties by looking for the {technicalnameproject}.amqp01.host. You need to combine the two elements via a dash -. An example of this is spwbsrv-test-cloud0001.emagizcloud.com. In an on-premise installation, you should ask your customer what the IP address or DNS name is to connect to the machine on which your runtime is running. If the runtime runs locally on your laptop, the host equals localhost.
38 +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:
43 43  
44 -=== 3.3 Port and Path ===
40 +[[image:Main.Images.Microlearning.WebHome@novice-devops-perspectives-annotations--annotation-best-practice-async-routing.png]]
45 45  
46 -The location determines whether or not the port needs to be defined to get to the endpoint. If the endpoint is hosted in the eMagiz Cloud, the port is *not* part of the endpoint. However, when you host your endpoint locally, the endpoint becomes part of your endpoint. Set up your route properly to make this piece work in the eMagiz Cloud. More on that in our Cloud Management courses. You can determine the port for the endpoint or the route by navigating to the infra flow of the runtime through which you host your SOAP web service. You can also find the remainder of the path to the WSDL location in the "infra flow."
42 +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:
47 47  
48 -The infra flow has a support object of the type "Dynamic WSDL". Here, you see the default location of the hosted SOAP endpoint, which is http://localhost:${entry.connector.ws.port}/ws/{soap WS name}/. Based on this, you can find the WSDL by adding {Id}.wsdl to the URI. In this example, when hosting the SOAP web service on-premise, a valid URI would be {{code}}http://localhost:8099/ws/soapgn3-connector/soapgn3-connector.wsdl{{/code}}.
44 +[[image:Main.Images.Microlearning.WebHome@novice-devops-perspectives-annotations--describe-parts-of-flow.png]]
49 49  
50 -{{info}}Note that when running your web service in the eMagiz cloud, the first part (the host part) will change depending on your configuration in Deploy Architecture and the cloud slot on which you are running. An example URI, in that case, would be {{code}}https://soap-test-cloud0000.emagizcloud.com/ws/soapgn3-connector/soapgn3-connector.wsdl{{/code}}{{/info}}
46 +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:
51 51

48 +[[image:Main.Images.Microlearning.WebHome@novice-devops-perspectives-annotations--describe-crucial-part-of-cdm.png]]
53 53  
54 -== 4. Key takeaways ==
50 +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.

56 -* The endpoint consists of the following elements:
57 - ** Starts with https:// or http://
58 - ** The second part is the host (i.e., where the endpoint is running)
59 - ** The third part is the port on which the incoming traffic is accepted
60 - ** These three things combined make up the first part of our endpoint, which will vary per environment
61 - ** Following that, we have a static remainder of the endpoint that is built up as follows: /{soap WS name}/{Id}/
62 - ** If you want to get to the WSDL, add the name of the WSDL (which is defined by the ID given to the "Dynamic WSDL" support object) and the .wsdl extension to the endpoint when viewing it in the browser
63 -* The relevant information can be derived from the "Dynamic WSDL" support object and by determining where the endpoint is hosted

65 -== 5. Suggested Additional Readings ==
54 +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.
