[OAI-implementers] VRA in OAI-PMH

[Sarah L. Shreeves]

Hi Will,

You've touched on an issue that is coming up in various forums....

I think that your assumptions are correct - Dublin Core and variations of 
Dublin Core are the most used schemas. MARC is used a fair amount as well, 
though I don't know of many service providers that are making use of the 
MARC records (please correct me if I'm wrong). OLAC (the Open Language 
Archive Community) has adapted Dublin Core (beyond the dcterms list) to 
meet their particular needs (see 
http://www.language-archives.org/OLAC/metadata.html#The%20metadata%20set 
for more information). Also, there are probably closed systems where 
schemas other than Dublin Core are being used.

There have been more conversations among service providers - particularly 
those within the Digital Library Federation - recently about the need to 
actively encourage the use of metadata schemas in addition to Dublin Core. 
Dublin Core is useful in so far that it provides a -somewhat- common 
denominator, but we at Illinois and other service providers have found that 
DC use is so variant that it takes significant resources to normalize it 
and massage it into a useful form. If data providers would provide their 
native metadata schema as well as DC (to be conformant) we could 
potentially make better use of it. Even qualified DC provides more useful 
semantics than simple DC.
