Hi, We're trying to define a OAI set for records corresponding to the pattern 0247_a:'urn:nbn:ch:rero' but which are OLDER THAN 6 MONTHS.
How can we implement the second criterion? The OAI Repository Admin Interface does not propose date-based criteria, nor does oaiarchive, apparently. Is there any other way of doing this from Invenio, before resorting to a custom script? Thanks in advance. Best regards, Miguel Invenio v0.99.1 http://doc.rero.ch/
