Deliverable D3.1 - Open API design and implementation for the 6G-SANDBOX Library

The main scope of this document is to report the design and implementation activities conducted towards realising the openness approach of the 6G-SANDBOX, an approach that enables the abstraction of network and experimentation capabilities, allowing for the creation of Trial Networks. As Trial Network we define a fully configurable, manageable, and controllable network which may composed of virtual and/or physical elements, and it can support experimentation services, such as technology validations and measurement campaigns. The 6G-SANDBOX approach for the Trial Networks is built upon two main principles, namely a) the use of open and standardised APIs (based on the 3GPP Common API Framework - CAPIF) for exposing the capabilities of each of the Trial Network elements, and b) the hosting of Trial Network software components in a common repository, called in the project framework as 6G Library, which eases an experimenter to perform a modular and automatic deployment of a Trial Network by selecting on demand the required elements from the library.
