What happend to grounding in description layer and what is quality and is it used??

[flomickl]

Hi
still working on the processor documentation.
During this process, I was wondering that the functions of the groundings are no longer used in the declairMethod.

So this "old" picture is out of date, I guess.
Was it replaced with something else or now totally in the backend?

What happend to it, why and why are the method then still integrated?

.supportedFormats(TransportFormat... format)
supportedFormats(List< TransportFormat > formats)

supportedProtocols(TransportProtocol... protocol)
supportedProtocols(List< TransportProtocol> protocols)

Furthermore
I did not find any examples of the quantity layer.
The only part I found was in the meassermentURI, but I guess this is also part of the Event Schema itself?

I want to create a newer version of it:

How would you describe it now?

Grounding is still being used, but we typically don't define it directly in the data processor anymore, but in the provideServiceDefinition method of the submitter to ease the defintion of pipeline elements. So when registering a messaing fromat or protocol, the description is automatically added to the processor.
Quality has been removed for now, as we didn't make any real use of it and were trying to simplify the codebase.

ah good to know.
So for now, the event schema is the only layer.

and these are the variables from the event schema that are still used?

SP Class	Name	Type	Description
Class EventProperty	label	String
Class EventProperty	description	String
	measurementUnit	String
Class EventProperty	boolean required	boolean
Class EventProperty	propertyScope	String
Class EventProperty	index	int
Class EventProperty	runtimeID	String

and this variables are not in use?

spcLASS	Name	Type
Class EventProperty	eventPropertyQualities	ArrayList
Class EventProperty	requiresEventPropertyQualities	ArrayList
	String valuesSpecitication	String
