[OAI-implementers] Requesting a part of a record possible with OAI-OMH?

[Joachim Wackerow]

Is it possible to offer/request only a part of a record with OAI-PMH?

For example: exists a way to request only the "dc:title" of an identifier?

I browsed the open archives web site and found only the verb 
"GetRecord". In addition to offer or request a whole record, we would 
like to offer or request only one element of a XML document stored in a 
record.

Background:
Requesting a whole record with DC information is no problem. But we are 
thinking about using OAI-PMH to offer DDI-structured information on 
social science surveys. DDI is an extensive description format (in XML) 
with ca. 300 elements on surveys (http://www.icpsr.umich.edu/DDI/). For 
some scenarios it would be more effective to offer/request only one 
element or one element group of the xml document.
