SAP CPI to BTP NEO Document Service

Hi All,

I am looking into the possibility of storing documents in SAP BTP NEO document service using CPI.

So far I have seen that Document Service is OpenCMIS which uses Apache Chemistry.
The examples all seem to take the approach that a java application is build on top of document service for storing documents.

I just want to connet CPI to it and store documents.
Has anyone ever done this? The documentation talks about the OpenCMIS API, but I do nit really see a description of this API and am wondering if this can be consumed by CPI at all.

Thanks

Tom
