How to set the display icon for a class?

[Tim Smith]

Hi,

I would like to be able to change the icon for instances (from the purple diamond) to a custom icon based on class membership - e.g. like I see with instances of edg:BusinessFunction.

Is it possible to assign an icon to a class?  If so, how would I do this?

Thanks,

Tim

Hi Tim,

Please see https://datashapes.org/propertyroles.html#IconRole 

This requires 7.1.

Thanks Irene!

This is good to know if I am able to upgrade to full EDG at some point.

I noticed the description for IconRole indicates it sets the Icon in trees and at the top of the form.  Is it possible to do this in a list of values produced by a property shape on a form?

For example, we use "generic" properties like "composed of" to define the composition of things.  Sometimes people use the same name (i.e. label) for instances of different classes.  In this context, this makes sense but it makes the list of instances shown with the property shape ambiguous.  I would like to either show the icon with the instance label or be able to append the class name to the instance label for display on the form.  In the screenshot below, one entry is an Order, the other is a Plan which, in this case, is shown by the labels but in other cases it is not so being able to use an icon or append the class name would be very helpful.

For example, we use "generic" properties like "composed of" to define the composition of things.  Sometimes people use the same name (i.e. label) for instances of different classes. 

During editing, if there are two instances with the same label, they will be differentiated in the dropdown e.g:

Once selected, both values will be displayed the same way. However, on the mouse over, details for each are shown, including type and icon e.g.,

Another option is to use a tabular view, described here: https://datashapes.org/forms.html#ValueTableViewer

You would need to define a Node Shape (e.g., SimpleTableView) with just two properties - label and type. It is not necessary to give it a target. Then, specify for the property shape in question:

        dash:viewer dash:ValueTableViewer ;

sh:node ex:SimpleTableView .

This will get you a table with two columns: Label and Type.

I believe all of this is available in 7.0.

In this context, this makes sense but it makes the list of instances shown with the property shape ambiguous.  I would like to either show the icon with the instance label or be able to append the class name to the instance label for display on the form.  In the screenshot below, one entry is an Order, the other is a Plan which, in this case, is shown by the labels but in other cases it is not so being able to use an icon or append the class name would be very helpful.
