Discussion:

The client must have a standard way of interacting with Collection UROs. This includes communication with UROs and URO behavior. The URO receives a Collection root node from the client via gRPC and performs pre-programmed behavior combined with client input. URO pre-programmed behavior references default attributes of nodes that are required for the successful execution of the URO. The URO standard will begin by writing two go library packages.

1. The gRPC API for queuing default behavior of a URO.
2. The UOR storage provider interface is used to translate URO content references to UOR attribute references.

Task:

Write the URO gRPC API for queuing default behavior of a URO and the UOR storage provider interface.
