How do I access the submodel elements via REST API?

[faelivrintelemnar]

Hello everyone,

1. Is it possible to do POST-Requests via the REST API?

2. Will there be a documentation?

3. How do I access the submodel elements via REST API? I tried:
   http://localhost:51310/aas/3/submodels/identification/submodelelements/complete
   or
   http://localhost:51310/aas/3/submodels/identification/submodelelements/assetid
   and it didn't work.
