Dear all,


in the mailing list archive it looks like my mail from yesterday wasn't
sent out to the list members. Please excuse me, if you receive this a
second time now.


Despite the support of Patrick Hochstenbach
(https://twitter.com/hochstenbach/status/1017087798132736002, thanks a
lot!) I cannot achieve my desired result.


I want to write the following set as MARC/XML into a file (or many

My approach, following the advice I received:

catmandu convert OAI --url https://www.tib.eu/oai/public/repository/open
<https://www.tib.eu/oai/public/repository/open>  --set
collection~tibcat_solr~documentType:r --metadataPrefix marc_xml
--handler marcxml to MARC > output.xml


This leads to the following error message:

Use of uninitialized value $\ in concatenation (.) or string at
/usr/local/share/perl/5.22.1/HTTP/OAI/Repository.pm line 169.


I use Catmandu 1.09 on Ubuntu. Any advice on how to proceed is very
