Please help me!

Dear sir/madame:

i need your help in locating a xml-schema that can define the structure of 
humanities and social sciences journals. i've looked everywhere on the web 
and cannot find any infomation, so what i would like to know is can you 
help me? i work at the Rare Book Division at McGill University, Montreal 
and there're many journals that need to be digitally preserve. Your help is 
most appreciated. Thank so much.

Many Thanks;
Steven Gee
