Hi,

Thanks for your help, the query worked! Now I have two follow-up questions:

1.      The query doesn’t seem to make use of the resumption tokens, at least the file output.xml contains only 10 entries. From what I understand from https://metacpan.org/pod/release/HOCHSTEN/Catmandu-OAI-0.16/lib/Catmandu/Importer/OAI.pm, there is no parameter to turn this on. The parameter resumptiontoken seems to serve only as a starting point. How do I get all records I queried?
2.      Is there a way to harvest  only the 336.835 records from https://www.tib.eu/oai/public/repository/open?verb=ListRecords&metadataPrefix=marc_xml&set=collection~tibkat_solr~documentType:r<https://www.tib.eu/oai/public/repository/open?verb=ListRecords&metadataPrefix=marc_xml&set=collection%7Etibkat_solr%7EdocumentType:r> without using sets? The set containing the records I’m interested in would be significantly larger (https://www.tib.eu/oai/public/repository/open?verb=ListRecords&metadataPrefix=oai_dc&set=tibkat with 3.612.946 records)

Not from the command line interface. But every importer is also an Catmandu::Iterable, you in perl you can apply:

   my $importer = Catmandu::Importer::OAI->new( .. );
   $importer->slice( $start, $limit )->each(sub{
      ..
   });

That doesn't mean although that only $limit records will be fetched in the background (the oai repo determines the size of each page).


Best,
Christian

Hi,

easy answer here: your selected set "collection~tibcat_solr~documentType:r" does not  exist (according to https://www.tib.eu/oai/public/repository/open?verb=ListSets).

Without the set parameter it works well

catmandu convert OAI --url https://www.tib.eu/oai/public/repository/open --metadataPrefix marc_xml --handler marcxml to MARC > output.xml

(but it doesn't provide an XML ;-) you have to specify a type).

So, one looks ok:
catmandu convert OAI --url https://www.tib.eu/oai/public/repository/open --metadataPrefix marc_xml --handler marcxml to MARC --type XML > output.xml

Best,

Vitali

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 files): https://www.tib.eu/oai/public/repository/open?verb=ListRecords&metadataPrefix=marc_xml&set=collection~tibkat_solr~documentType:r<https://www.tib.eu/oai/public/repository/open?verb=ListRecords&metadataPrefix=marc_xml&set=collection%7Etibkat_solr%7EdocumentType:r>
My approach, following the advice I received:
catmandu convert OAI --url 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 welcome.

Best,
Christian
