How to load EnergyADE extensions #41

Closed PieterBlomme closed 1 year ago

PieterBlomme commented 1 year ago

I'm trying to convert a CityGML file that uses the EnergyADE extension.
I'm getting a warning that 'Non-CityGML content is skipped unless a matching ADE extension has been loaded'. How would I load the EnergyADE extension? I can't find any documentation on it.

(base) ubuntu@P220024:/mnt/c/Users/BLOMMEP/Downloads/citygml-tools-2.0.0$ ./citygml-tools --extensions=extensions --log-level=debug to-cityjson ../Mandel_20220701.gml [13:17:36 INFO] Starting citygml-tools.

citygml-tools does not handle CityGML ADEs in a generic way. It needs a Java software module that adds support for reading and writing the ADE data. Since citygml-tools is built on top of citygml4j, this module must be implemented against the ADE API of citygml4j. Currently, there is no such module for the EnergyADE freely available for the latest version of citygml4j.

Independent of this, it seems you want to map the EnergyADE content to a CityJSON representation?! As far as I know there is no CityJSON extension defined for the EnergyADE. So, even if there was an EnergyADE module for citygml-tools, how should the tool know how to map EnergyADE content to CityJSON?

Thanks for the info, in that case the warning is just about unclear I guess.

I'm happy to improve it if you have a good suggestion.
