Create Semantic Group

There are four ways in which you can create semantic group depending on a template:

1. Create new template while creating semantic group

Click on Create group button in Data Semantics tab
Click on Create template link

chose-a-template-from-already-created.pn

You will immediately get all the prompts necessary to make a template
Enter name for your template
Continue by adding Attribute - provides additional information about the semantic group
Choose Attribute type
If you check Attribute required box, value text box will be mandatory for all Attribute types

If numeric - enter number as value
If string - enter text as value
If boolean - check value box
If location - enter coordinates as value
You can add multiple number of Attributes

Continue by adding placeholder for Sensor’s feed
Go to Sensors tab
Click on Add sensor link

In new text field enter Sensor name, Reading type and Unit

Now that you created a placeholder, click on Map data button to map sensor’s feed to the placeholder
New window will pop up with the list of all the sensors’s feeds that can be mapped (have the same Reading type and Unit)
Choose the feed
Click Save
You can add multiple number of feeds
Continue by adding placeholder for Actuator
Go to Actuators tab
Click on Add actuator link
In new text filed enter Actuator name and Reading type
Please note that you should only choose reading types which are marked as actuators

Now that you created a placeholder, click on Map data button to map actuator to the placeholder
New window will pop up with the list of all the actuators that can be mapped (have the same Reading type and Unit)
Choose the actuator
Click Save
You can add multiple number of actuators
Continue by adding placeholder for Alarm
Go to Alarms tab
Click on Add alarm link
In new text field enter Alarm name

Now that you created a placeholder, click on Map data button to map alarm to the placeholder
New window will pop up with the list of all the alarms
Choose the alarm
Click Save
You can add multiple number of alarms
Now that you have created the template and the semantic group, click Save to finalise the process
Semantic group will appear in Data Semantics tab in Semantic groups field
Template you created will appear in Templates tab
Now you can continue with making your semantic group

2. Create template separately and then create semantic group

Go to Templates tab
Click on button to create new semantic group template

You will jump to Create templates screen
Create template as previously described

3. Choose template from those already created

This will automatically generate all the placeholders for Attributes/Sensors’ feeds/Actuators/Alarms you have created with a template
To continue the process, check Update template ‘[name]‘ box
Click Save and finalise the process of creating a semantic group
Semantic group will appear in Data Semantics tab in Semantic groups field

4. Create semantic group without creating template

Go to button and start creating semantic group as described in the beginning of this section
Skip choosing template or creating new template steps

Create your semantic group by adding any Attribute/Sensor/Actuator/Alarm
Click Create to complete the process
Your semantic group will be created and listed in the Semantic groups tab

Modify Semantic Group

You can modify semantic group in various ways:

Edit
Move to
Move to first level
Delete

Edit Semantic Group

To edit semantic group:

Click on a semantic group tile
You will jump to the box that contains tiles of feeds/actuators/semantic subgroups
Click on Edit group button above the box
New window will pop up with Info and Access tab

Info tab contains text file in which you can modify the name of the (sub)group

You can also Add attribute, Cancel and Update the changes you made
Access tab enables you to modify the access to your semantic (sub)groups and the data it contains
Click on Edit group button
New window will pop up with Info tab

In Info tab you can edit group’s attribute or even add some new ones.

Move to

Move to option in semantic group screen enables you to move the semantic GROUP in question to another semantic group and make it a SUBGROUP.

To do so:

Click on Move to button
New widow will pop up with the list of all the semantic groups you created/have the access to

Choose the semantic group
Click Save
Your semantic group is now a subgroup of the group you have chosen

Move to First Level

Move to First Level option allows you to move semantic SUBGROUP to the first level and make it a first level semantic GROUP.
