[Dspace-general] An institution's IR vs. Subject Repository

[Beth Tillinghast]

Hi,

I have just run into my first case where I am finding our IR in 
competition with a Subject Repository. I've been working with an 
institutional center which is outside of our university but very 
closely affiliated with it. We were about to make some final 
decisions about community and collection development when my contact 
discovered a new Subject Repository supporting the type of research 
conducted at their Center and wants to explore this alternative 
before committing to submitting their work to our university repository.

I am wondering if others have run into this dilemma and can provide 
me with many good reasons why submission should take place in and 
institutional repository rather than a subject repository?

Also, as a side question, I know you can item map within your own 
DSpace instance, but is it possible to item map to another DSpace instance?

Thanks for the feedback,
Beth Tillinghast
