Defined in:
app/service_adaptors/illiad.rb

Overview

Just creates an OpenURL link out, corresponding to the current OpenURL. But tweaked in ways to try and work out for sending to ILLiad.

If you use SFX, you may want to just use SFX’s built-in ILLiad targets, which will generally be picked up by the SFX Umlaut service.

But if you don’t or if you are unhappy with what SFX is doing, you could turn off ILLiad target(s) in SFX (or configure Umlaut SFX adapter to ignore them), and use this instead.

# Pre-empting

You may want to show ILLiad links only if there is no fulltext, or only if there is no fulltext from a certain service. You can use Umlaut’s standard service pre-emption configuration for that.

Do not produce ILLiad links if there are ANY fulltext links already produced in the request. In umlaut_services.yml:

illiad:
  type: Illiad
  base_url: http://ill.university.edu/site/illiad.dll/OpenURL
  priority: 4
  preempted_by:
    existing_type: fulltext

Or, preempt ILLiad links only if there are fulltext links created by SFX specifically (assume “SFX” is the id of your sfx service in umlaut_services.yml)

illiad:
  type: Illiad
  base_url: http://ill.university.edu/site/illiad.dll/OpenURL
  priority: 4
  preempted_by:
    existing_service: SFX
    existing_type: fulltext

Pre-emption can only take account of services already generated before ILLiad service is triggered, so you’d want to make sure to give ILLiad a priority greater than the services you want to potentially preempt it.

# Config parameters ## Required

## Optional

  • display_name: Default “Place ILL Request”

  • sid_suffix: Default “ (via Umlaut)”, appended to existing sid before sending to ILLiad.

  • notes: Some additional notes to display under the link.
