I just had the opportunity to watch the video of Karen Smith-Yoshimura’s presentation of “Linked Data Implementations-Who, What and Why”. Video available here.
The video is a presentation of survey results from 2 surveys, one in 2014 and one in 2015. OCLC Research has shared the data here.
Wikidata is mentioned a few times as a source of linked open data that is consumed by some of the projects discussed in the presentation.
I found this video to be a great overview of linked data projects across libraries and museums.
