Thank you! Now I got message which says: *Unable to create an Entity that does already exist* * * as I understand, this means that I did it right first time. How I can read ID of this Entity? I did not use -v switch first time when I tried upload, and now I do not know ID. Or maybe I do, but I am not aware of that...
And only one more simple question... Could you please provide me a code example? I will try to search archive, or other resources that you gave me. Anyway, I would be grateful if you could help me. Once again, thank you very much!
