=head1 NAME

|
|
|
C4::External::BakerTaylor
|
|
|
|
=head1 DESCRIPTION
|
|
|
|
Functions for retrieving content from Baker and Taylor, inventory availability and "Content Cafe".
|
|
|
|
The settings for this module are controlled by System Preferences:
|
|
|
|
These can be overridden for testing purposes using the initialize function.
|
|
|
|
=head1 FUNCTIONS
|
|
|
|
=head2 availability($isbn);
|
|
|
|
$isbn is a isbn string
|
|
|
|
=head1 NOTES
|
|
|
|
A request with failed authentication might see this back from Baker + Taylor:
|
|
|
|
<?xml version="1.0" encoding="utf-8"?>
|
|
<InventoryAvailability xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" DateTime="2008-03-07T22:01:25.6520429-05:00" xmlns="http://ContentCafe2.btol.com">
|
|
<Key Type="Undefined">string</Key>
|
|
<Availability>false</Availability>
|
|
<Error>Invalid UserID</Error>
|
|
</InventoryAvailability>
|
|
|
|
Such response will trigger a warning for each request (potentially many). Point being, do not leave this module configured with incorrect username and password in production.
