Re: [basyx-dev] BaSyx minimal server example

[Nicolas DUMINY <nicolas.duminy@xxxxxxxxxxxxxxxxx>]

Dear BaSyx development team,

This was true, I used an older version of BaSyx (1 month old), and after updating it, I don't have problems with test classes that should be main ones any more.

However, I have questions regarding how to automatically navigate through deployed AAS.
In the examples, the AAS ids, submodel ids and properties paths and ids are always known in advance and used as such.
I wonder, how a device, such as a AAS/submodels dashboard, could automatically detect every AAS connected and their structure (submodels, properties) without such prior knowledge.
Such dashboard would need to read these structures dynamically, but other devices could need to write in these too.
I'm looking at a generic case, where the registry is a SQL based-one, and the AAS/submodels can be either self-hosted or deployed on a AAS central repository (not known beforehand).

Can you explain to me how this navigation through AAS/submodels for reading/writing must or should be conducted?

Best regards,


Nicolas Duminy

Is it possible that you are running an older version of the SDK? BaSyxContext is not located any more within the test suite. It currently resides in org.eclipse.basyx.vab.protocol.http.server within the SDK. Thus, you can easily use or extend it without the need to rely on test code.

Best regards,
Frank

Betreff: [basyx-dev] BaSyx minimal server example

Dear BaSyx development team,

I'm having great difficulty to create a simple and minimal example that uses BaSyx with a simple asset (only contains a status that can change).
Indeed, I just don't know what classes to use.
Are some classes in the test source folders core functionalities (sdk/test, or components/test)?

I would simply like to have AAS deployed on a server, with a registry that show how to access it, special components that integrate my legacy devices into BaSyx (updating AAS submodels when device status changes).
I want to mimic the org.eclipse.basyx.examples.scenarios.device.RunSimpleTCPDevice test, but without TCP connection to the device.
So I'm trying to create a subclass of org.eclipse.basyx.components.devicemanager.DeviceManagerComponent that will handle the integration of my devices to BaSyx.
And I want to be sure that my implementation uses as few functionalities as possible, and no test-specific classes.

But I'm stuck at the moment, as I don't know how to avoid the org.eclipse.basyx.examples.contexts.BaSyxExamplesContext_1MemoryAASServer_1SQLDirectory class to create the network infrastructure for handling the AAS server and the registry or even avoiding org.eclipse.basyx.testsuite.support.backend.servers.BaSyxContext.
Isn't there any other way (simpler way) to create the basic network infrastructure, than to use those test classes?


Best regards,


Nicolas Duminy
