NAME ^

Catmandu::Importer::OAI - Package that imports OAI-PMH feeds

SYNOPSIS ^

    use Catmandu::Importer::OAI;

    my $importer = Catmandu::Importer::OAI->new(
                    url => "...",
                    metadataPrefix => "..." ,
                    from => "..." ,
                    until => "..." ,
                    set => "...",
                    handler => "..." );

    my $n = $importer->each(sub {
        my $hashref = $_[0];
        # ...
    });

METHODS ^

new(url => URL, %options)

Create a new OAI-PMH importer for the URL. Optionally provide OAI-PMH parameters: metadataPrefix, from, until and set. To parse metadata records into Perl hashes optionally a handler can be provided. This is a Perl package that implements two methods:

  * metadataPrefix  - which should return a metadataPrefix string for which it can parse
  the metadata
  * parse($dom) - which recieves a XML::LibXML::DOM object and should return a Perl hash

E.g.

  package MyHandler;

  use Moo;

  has metadataPrefix => (is => 'ro' , default => sub { "oai_dc" });

  sub parse {
      my ($self,$dom) = @_;
      return {};
  }

count

each(&callback)

...

Every Catmandu::Importer is a Catmandu::Iterable all its methods are inherited. The Catmandu::Importer::OAI methods are not idempotent: OAI-PMH feeds can only be read once.
