Module: Hyrax::AuthorityRenderingHelper

Defined in:
app/services/hyrax/authority_rendering_helper.rb

Overview

Shared rendering helpers for authority-backed values that may have been stored as either a real URI or as free text (the M3 metadata profile, plus bulk importers such as Bulkrax and Willow Sword, can both produce free-text values that the UI's authority dropdown did not constrain).

LINKABLE_URI_SCHEMES =

Schemes considered safe to emit in an <a href>. Anything else (notably javascript:, data:, custom schemes, or non-absolute strings like "moomin") is rendered as plain text so it cannot be activated as a link.
