It's my impression that dct:relation would be too generic a property. 
It's a little tough without a domain and range specified but it seems 
like dct:references is appropriate for citations as well as other types 
of resources.  Are you familiar with the bibo ontology[1]?  The property 
bibo:cites[2] might be useful for distinguishing a resource that is 
cited from a resource that is referenced.
