retrieve_resource_types

This X-Service enables you to retrieve a list of resource types by institution.

If there is no specific institution include file, the service will return the types from the generic file ./dat01/www_m_eng/type-include. If the generic file does not exist or is empty, the service returns an error message.

• login – Called once by the calling application with valid /X user name and password. The session-id retrieved should be passed to all other API calls
• retrieve_resource_types

Mandatory

1. SESSION_ID – X(50)

Optional

2. INSTITUTE – X(30)

Explanation of the mandatory and optional parameters:

• session_id: The session ID is the unique identifier of the login.
• institute – Default is blank – the service will use the generic resource types list. If specified, the service will look for the institution specific resource list.

Example 1:

<?xml version = "1.0" encoding = "UTF-8"?>
<x_server_request>
  <retrieve_resource_types_request>
    <institute>METALIB</institute>
    <session_id>TL6HGNJDJ8A93JCAY39U18LCJ5AM3XX1MMAS343RAHC8M5VATM</session_id>
  </retrieve_resource_types_request>
</x_server_request>

The XML output includes:

• • institute – The code of the institution as defined in ./vir00/tab_institute.
  • resource_types – The resource types as defined in ./dat01/www_m_eng/type-include[MetaLib:-inst].

1. If the session_id, provided as an input parameter, is not valid, the following error message appears in the XML output:

<error_code>0151</error_code>
<error_text>You are not authorized to use this function</error_text>

This can be caused by not using the session_id returned from the Login X-Service.

2.If this X-Service was activated after the session had timed out:

<error_code>2050</error_code>
<error_text>session timeout</error_text>

3. If one of the parameters is missing:

<error_code>2038</error_code>
<error_text>Missing element from XML request - " verification ".</error_text>

4. If no resources were found for the requested institution:

<error_code>6044</error_code>
<error_text>No resource type for institution '<institute>'</error_text>

5. If the institution does not exist:

<error_code>6025</error_code>
<error_text>Institute '<institute>' does not exist</error_text>

(Up to metalib_version 4.3.4 (657))

This service has problems with type name and display_name containing non ASCII characters: the characters will be dropped. If you had the type-include file utf8 encoded, they would display correctly but the types would no longer work in the Management inteface (/V is fine)…

Also, the display_name contains a lot spaces around the name which must be stripped.
