ItemName from ItemLink

[trou23]

I'm going throught the guild sales transactions and pulling the data out using the GetGuildEventInfo method, which when dealing with a guild store sale returns the item link of the item that was sold. My question is, the item link sometimes has a ^n or ^p and I'm not sure why. Why are they being included in the item link?

Examples:
"|H0:item:54512:81:50:45870:81:50:0:0:0:0:0:0:0:0:0:5:0:0:0:0|hruby necklace of reduce spell cost^n|h"
"|H0:item:45100:51:50:26580:51:50:0:0:0:0:0:0:0:0:0:1:0:0:10000:0|hcalcinium pauldron of health^p|h"

I'm also curious why sometimes the names come back in all lower case and sometimes in proper case. Is there a trick I'm missing here?

Thanks in advance.
