Hello W.,
Now I understand the issue, between:
- class attribute compartment: fields
- class operator compartment: method
To force the "series entry" to be on the upper attribute compartment, you can use the keyword: {field}.
Here is the result:
@startuml
class Event_or << Entity >> {
{field}[[https://www.openresearch.org/wiki/Property:Event_in_series{foreign key(pagename) of the Event series this event belongs to} series]] : TEXT
}
@enduml
You can use {field} and {method} modifiers to override default behaviour of the parser about fields and methods.
If that can help,
Regards,
Th.
