Hi Nguyen,

i'll assume that you're using OAI_DC as schema for exposing that information from the repository. 

By convention OAI_DC schema (simplified DC) establishes that authors must be exposed as dc.creator. However DSpace uses another schema (qualified DC), which uses dc.contributor.author to store author's, blocking this conversion isn't advisable (and it's only achieved with code changes). But that isn't the limitation, OAI_DC doesn't supports qualified elements, basically, it isn't correct to expose qualified elements, like dc.contributor.author, using OAI_DC.

I would recommend to expose metadata using QDC (the same used by DSpace by default).

You can also use the XOAI add-on (another OAI interface for DSpace) which allows you to modify every schema in a simple way (http://www.lyncode.com/dspace/addons/xoai/). The new DSpace 3.0 is going to replace the old OAI module by this new one (XOAI).
