Bug 23173: Provide core infrastructure
This patch adds the required infrastructure to enable ILL availability plugins to intercept the request creation process and, using the supplied metadata, search for and display possible relevant items from whichever availability plugins are installed. Currently three availability plugins exist: z39.50 - Searches any number of the Koha instance's configured Z targets https://github.com/PTFS-Europe/koha-plugin-ill-avail-z3950 EDS - Searches the EBSCO Discovery Service https://github.com/PTFS-Europe/koha-plugin-ill-avail-eds Unpaywall - Searches the Unpaywall API for possible open access versions of the requested item https://github.com/PTFS-Europe/koha-plugin-ill-avail-unpaywall The Unpaywall plugin is intended to serve as a "reference" plugin as the API it deals with is extremely simple Signed-off-by: Niamh Walker-Headon <Niamh.Walker-Headon@tudublin.ie> Signed-off-by: Kyle M Hall <kyle@bywatersolutions.com> Signed-off-by: Martin Renvoize <martin.renvoize@ptfs-europe.com>

Koha::Illrequest::Availability - Koha ILL Availability Searching
|

|

=head1 SYNOPSIS
|
||||
|
||||
Object-oriented class that provides availability searching via
|
||||
availability plugins
|
||||
|
||||
=head1 DESCRIPTION
|
||||
|
||||
This class provides the ability to identify and fetch API services
|
||||
that can be used to search for item availability

my $availability = Koha::Illrequest::Logger->new($metadata);
|
||||
|
||||
Create a new Koha::Illrequest::Availability object.
|
||||
We also store the metadata to be used for searching

|

|
||||
Given our metadata, iterate plugins with the right method and
|
||||
check if they can service our request and, if so, return an arrayref
|
||||
of services. Optionally accept a hashref specifying additional filter
|

parameters
