student picks site out and about in Philadelphia or greater environs

example korean war memorial in Philadelpihia

Student transcribes related primary source (newspaper coverage of events of Korean war etc)
Student annotates the now digitized primary source
Student annotates on google maps with above as well as other links s/he curates from web

so obviously I’m using google maps for part, but I’d like something like the omeka interface to allow students to collectively put up their original source, and then its annotation, but I can’t figure out how to do that in Omeka.  I’m also worried about students abilities to run Omeka.  I also am not sure what the best platform for text annotating is.
