I'm also interested just to read item information from chat packet.
At first instance, the information sent into the chat packet looks like ID's because I didn't found relations with the item itself, not even stats.
So for me, the ID's are sent with a unique separator pointing to a different packet which contains all this info (Not sure if iSRO works similar.. just theory, I'm not testing myself this stuff since the server I played didn't have item link)

I'll be entering to TRSRO in a few minutes to check that.
