[Dspace-general] submission, searching, and displaying non-dublin core metadata

[Marvin Weaver]

I just got dspace 1.5.2 up and running.  I found where in the metadata 
admin I could create a metadata schema for data not included in Dublin 
core.  Now I cannot figure out how to use the schema in the xmlui.  I 
would like to add it to the submission page, make it searchable, and 
display it in a number of places.  An entry in the FAQ seems to indicate 
that only Dublin core can be used.  If this is the case, why is the 
option to create other metadata schemas included?  I've noticed some 
discussion regarding using dublin core fields for other than their 
intended purposes (and that it is not a good idea).  Is this the only 
way to use data fields that are not in dublin core?  The last option 
seems to be adding new elements to dublin core that are not defined in 
dc.  Is this an OK thing to do?
What I am trying to do is add an author type of "SJUfaculty" to be able 
to select only our own faculty when there are non-SJU collaborators 
involved in a work.
Also, we need to do a large import so whatever solution I use needs to 
be compatible with the batch input program.
Thank you,
