From: Dan Scott Date: Tue, 19 Sep 2017 02:14:04 +0000 (-0400) Subject: Realtime Wikipedia description lookups X-Git-Url: https://old-git.evergreen-ils.org/?a=commitdiff_plain;h=281e7517243edfd5eb32cd400b8f359373c10ff4;p=contrib%2FConifer.git Realtime Wikipedia description lookups These are English-only but provide the first sentence of the Wikipedia description of the performer, as well as a link to the related Wikipedia page via the WP icon. We also remove the non-functioning toggle code and generate unique DOM IDs for each of the musicians.
