[Dspace-general] How does DSpace support richful metadata, such as the record in CiteSeer?

[Scott Yeadon]

Hi Xiaoyan,

If you have RDF metadata you may be better off storing it as a bitstream within the item. The example you give holds metadata not only about the item (i.e. its author) but metadata about metadata (i.e. the author's address and affiliation). The DSpace database only handles flat metadata models not hierarhical ones.

There is a qualified DC crosswalk incoporated in the next version of DSpace (1.4) which will be released in alpha shortly (or you can have look at it in the current CVS).

Scott.

We are currently uploading data from the CiteSeer collection to DSpace, and 
face the problem of how
to map richful metadata to something that DSpace can manage well. Further, we 
plan to make the data
accessible through NSDL, but it is not clear precisely how to use Dublin Core 
with
qualifiers (e.g., how to apply the ideas of DC-Ed) in a way suitable for NSDL
(www.nsdl.org).

We suspect that DSpace can only use strings, not RDF, for entries in the 
metadata?

One particular concern is how to map rich information into DSpace records. 
Normally
we would use DC:creator, but how would we code:
<oai_citeseer:author name="Gabriele Scheler">
   <address>80290 Munchen , Germany</address>
   <affiliation>Institut fur Informatik; Technische Universitat 
Munchen</affiliation>
</oai_citeseer:author>

Please advise.

Thanks,
xiaoyan
