The Golang coreBOS Web service library can be found here. You can add it to your project with:
go get github.com/tsolucio/corebosgowslib
and then import it into your code with
import "github.com/tsolucio/corebosgowslib"
Now you can use the corebosgowslib
object to access your coreBOS install.
In this repository you can find a test script to get you started.
Enjoy!!
