=head1 NAME
C4::ILS-DI::Services - ILS-DI Services
=head1 DESCRIPTION
Each function in this module represents an ILS-DI service.
They all takes a CGI instance as argument and most of them return a
hashref that will be printed by XML::Simple in opac/ilsdi.pl
=head1 SYNOPSIS
use C4::ILSDI::Services;
use XML::Simple;
use CGI;
my $cgi = new CGI;
$out = LookupPatron($cgi);
print CGI::header('text/xml');
print XMLout($out,
noattr => 1,
noescape => 1,
nosort => 1,
xmldecl => '<?xml version="1.0" encoding="ISO-8859-1" ?>',
RootName => 'LookupPatron',
SuppressEmpty => 1);

availability of the items associated with the identifiers.
Parameters:
=head3 id (Required)
list of either biblionumbers or itemnumbers
=head3 id_type (Required)
defines the type of record identifier being used in the request,
possible values:
- bib
- item
=head3 return_type (Optional)
requests a particular level of detail in reporting availability,
possible values:
- bib
- item
=head3 return_fmt (Optional)
requests a particular format or set of formats in reporting
availability

=head2 GetRecords
Given a list of biblionumbers, returns a list of record objects that
contain bibliographic information, as well as associated holdings and item
information. The caller may request a specific metadata schema for the
record objects to be returned.
This function behaves similarly to HarvestBibliographicRecords and
HarvestExpandedRecords in Data Aggregation, but allows quick, real time
lookup by bibliographic identifier.
You can use OAI-PMH ListRecords instead of this service.
Parameters:
- id (Required)
list of system record identifiers
- id_type (Optional)
Defines the metadata schema in which the records are returned,
possible values:
- MARCXML

=head2 GetAuthorityRecords
Given a list of authority record identifiers, returns a list of record
objects that contain the authority records. The function user may request
a specific metadata schema for the record objects.
Parameters:
- id (Required)
list of authority record identifiers
- schema (Optional)
specifies the metadata schema of records to be returned, possible values:
- MARCXML
=cut
