We had a similar need. Our library discovery layer pulls content from
DSpace using the OAI harvester.
We needed to distinguish full text content from non-full text content in
our OAI metadata. We noticed that we could key off of data within the
dc.provenance field.
Here is an SQL version of the query we ran for this purpose.
and exists
(
select 1
from metadatavalue m
where m.item_id = i.item_id
and m.metadata_field_id = (
select metadata_field_id from metadatafieldregistry mfr
where mfr.element = 'description' and mfr.qualifier = 'provenance'
)
and (text_value ~ '^.*No\. of
bitstreams.*\.(PDF|pdf|DOC|doc|PPT|ppt|DOCX|docx|PPTX|pptx).*$')
)
