I do not know exactly how PS uses the term, but -in general- "metadata" 
is information about the data, usually saved in the file. That is all 
the stuff in the file besides the actual photo -in this case- is 
metadata. It seems to have started as a HTML keyword and spread into 
other areas. Actual definition of "meta-" is beside, or after.

Note, that the term "comments" also fits into that definition, but you 
know how folks like to change the perfectly good names we already have...
