Using a "resumptionToken” when a search returns 51 or more data records

A “resumptionToken” facilitates the delivery of partial responses when a search returns 51 or more data records. The OAI harvester receives a token which it has to use for an additional request from the OAI repository in order to get the next partial response. If not all records have yet been delivered, a new “resumptionToken” is generated with each partial response and must be used to obtain the next. The element “resumptionToken” contains the attribute values of the current list position and the total number of data records (cursor="50" completeListSize="xxxxxx"). Each OAI response delivers a maximum of 50 data records. A “resumptionToken” is valid for no more than 30 minutes.
