[OAI-implementers] Sets in OAI-PMH and DSpace

[Sarah L. Shreeves]

In response to your question about how many people use sets for selective 
harvesting...

At UIUC for our Gateway to Cultural Heritage Resources 
(http://nergal.grainger.uiuc.edu/search/) we selectively harvest sets 
because our indexes are based on the general type of material (eg. images 
and video, text and sheet music, archival collections are our three very 
general groupings). Harvesting specific sets allows us to broadly 
categorize collections by type of material.

In our IMLS Digital Collections and Content project 
(http://imlsdcc.grainger.uiuc.edu) we are selectively harvesting sets that 
are specific IMLS funded digital collections.  For data providers which do 
not provide sets, we end up writing filters on our ends that grab the IMLS 
funded resources.

I think sets are going to be absolutely vital -- it'll be interesting, 
however, to see how they develop.  I think that data providers have tended 
to create sets based on their internal structures and needs;  it might be 
more productive to understand what service providers need/use sets for.
