unable to reproduce AAS server JSON serialization

[mhrimaz]

Hi,

I am using the official docker image of AAS server (eclipsebasyx/aas-server:1.3.0). However, the JSON response of AAS server is different than basyx-python-sdk JSON serialization result (Version: 0.2.2)

For example, when kind of submodel is instance there is no "kind":"Instance" in the output. In the image below you can see the structure is not consistent and this is reflected in the code too, however I don't know this is according to specification or just implementaiton difference.

And here you can see there are asset and assetRef on the left produced by AAS server. python sdk asset is equivalent to assetRef and asset is completely missing.

Is there any way to reproduce exact result of AAS server in python? or which java library should be used, basyx-java-sdk or eclipse-aas4j/aas4j or something else?

Please let me know if you require further information.

Which version of the asset administration shell model does this server use? Version 0.2.2 uses Version 2.0.1. of the AAS model (https://www.plattform-i40.de/IP/Redaktion/DE/Downloads/Publikation/Details_of_the_Asset_Administration_Shell_Part1_V2.pdf?__blob=publicationFile&v=6)

The output without "kind":"Instance" is still schema conform in V2.0.1, as the Kind=Instance per default, if nothing is given in JSON.

There is no assetRef in JSON Schema for the version V2.0.1 of the AAS. I guess all the content which is in "assetRef" shoud actually be in "asset".
