| Subject: | HTTP::OAI::Harvester GetRecord() method hangs? |
Dear reader,
the attached script is trying to get all records from
http://arachne.uni-koeln.de:8080/OAI-PMH/oai-pmh.xml .
The script is fetching one identifier at a time and then is trying to
get the according record via GetRecord(), but there the script is using
100% cpu and does not seem to end anymore.
I am not sure if the repository has changed something, but i think there
should be an error or the script should be able to get the data.
The first record could be get by
wget -O -
'http://arachne.uni-koeln.de:8080/OAI-PMH/oai-pmh.xml?verb=GetRecord&metadataPrefix=mets&identifier=oai%3Aarachne.uni-koeln.de%3Abuch%2F1'
Kind regards,
JB
