Hello,
i have a problem two understand the use of HasComponent and Organizes.
Have someone a good description or a short example for me?
Thanks for your help.
An example could be the model of a city.
The city has several homes. Each home would be part of the city and therefore referenced with HasComponent.
Each home – among many other tings – has a front door. Again referenced with HasComponent.
“Organizes” is mostly used to group related things. For the city, for instance, I could imagine a folder that groups all green front doors – i.e. this folder would contain “Organizes” References to several front doors which are also referenced via “HasComponent” from homes.

Hello Karl-Heinz,
first thanks for your example:
Is this a correct interpretation of your example?
Graph:
Almost 🙂
The arrow of the “Organizes” References should point from the “Homes with green doors” folder to the homes.

Thanks for your help again 😉
Then let me try to apply the example to a real server.
I have the following structure on a Server
The Server has the ReferenceType “Organizes”.
When i understand the example correctly it means that is “Server” not created in the Folder Objects. Server is only a Reference on a another Object on the Server.
Not sure I understand the question. The basic organization of an AddressSpace which includes “Objects” and “Server” and how they reference each other is defined in UA Part 5.
The “Server” object in some way is a standalone object. I.e. it isn’t a component of another object. To make it discoverable, however, the UA standard requires an “Organizes” Reference from the “Objects” folder to this “Server” object.

Ah, okay.
Without the organize Reference i have no chance to find the Server Object.
And why should i not use “has component” for the Server-Object?
Thank for your help 🙂
