I do this in jruby using the dspace-jruby gem I developed
see on GitHub https://github.com/akinom/dspace-jruby
<https://github.com/akinom/dspace-jruby>
#find items with given metadata value
items = DSpace.findByMetadataValue('pu.workflow.state', 'reviewed',
DConstants::ITEM)
# print their ids and handles
items.each do |i|
puts [i.getID, i.getHandle].join "\t”
end
#find bitstreams with metadata dc.type = other
bits = DSpace.findByMetadataValue('dc.type', 'other', DConstants::BITSTREAM)
# then go look at file name with an extension that you are interested in
bits.each do |b|
ext = b.getName.split('.')[-1]
if (["pdf", "txt", "jpeg"].include?(ext)) then
puts [ext, b.getID, b.getName, b.getParentObject.getID,
b.getParentObject.getHandle].join "\t"
end
end
# bitstreams for items with dc.contributor = ‘University of Stuff’
items = DSpace.findByMetadataValue('dc.contributor', 'University of Stuff',
DConstants::ITEM)
items.each do |i|
bits = i.getBundles('ORIGINAL')[0].getBitstreams
# similar to the above example
end
Let me know if you need help with using this
