[EP-tech] Re: Populating Eprints Repository with data from an OAI Data Provider



Hi Adam,

Hope I am not becoming a bother. I have decided to use the method for
importing that is explained here
http://www.nottingham.ac.uk/~uazmjg/eprints/archives/000074.html .

I have managed to create an xml file formatted as the one given.  I now want
to go to step number  3  of importing into archive. The steps are :
	
	bin/import_eprints archiveid dataset xmlfilename
	then run generate_views archiveid.

What I am not sure of is, is the keyword "dataset"   an argument that needs
replacement as with archiveid  and  xmlfilename? If it is an argument, how
or where should I get its value?

Data Provider

Hi Adam,

Thanks for the information and on the advice of not using SQL directly. I
have been trying to follow the code and  also looking at the tables in the
database, in particular the eprint table, where most of my harvested data is
destined to reside in. However, I am not sure how the authors of the
articles  harvested via OAI would be linked to the other imported data as
the authors are clearly stored in another table. I will appreciate having
any idea of the relationships between the table capturing the author names
and the eprint table;

Regards,

Admire

Hi

	I would strongly recommend against using SQL to write directly to
the database.  Using the EPrints API is the best way to do this, and you can
read more about that on the wiki (e.g.
http://wiki.eprints.org/w/Core_API#DataObj ).  Your code would look
something like this:


sub create_eprint_record
{
	my ($repository, $oai_data) = @_;
	#$oai_data is a hashref of fields that have been harvested via OAI
for a single record


	my $oai_data = get_oai_reco
	my $data = {};

	$data->{title} = $oai_data->{Title};

	#map the type from the harvester to the type in EPrints
	my $type_map = {
		'oai_type_1' => 'eprints_type_1',
		'oai_type_1' => 'eprints_type_2',
		'etc' => 'etc',
	}
	$data->{type} = 'article'; #default type
	if ($type_map->{$oai_data->{'Material Type'}})
	{
		$data->{type} = $type_map->{$oai_data->{'Material Type'}};
	}


	#more mapping



	#now that $data is complete, convert it into an eprint
	my $eprint = $repository->dataset('eprint')->create_dataobj($data);

	return $eprint;
}

Note that this was just typed directly into my email, so is almost certainly
not correct, but should get you started on writing your own function.

Best Wishes

using the  Net::OAI::Harvester. I have managed to harvest from the data
provider the following metadata:

create a complete item record in EPrints.  An SQL statement would be most
appropriate.
