has published "Analysis of 2018 International Linked Data Survey for Implementers" in the Code4Lib Journal.
Here's an excerpt:
A total of 143 institutions in 23 countries responded to one or more of the surveys. This analysis covers the 104 linked data projects or services described by the 81 institutions which responded to the 2018 survey—those that publish linked data, consume linked data, or both. This article provides an overview of the linked data projects or services institutions have implemented or are implementing; what data they publish and consume; the reasons given for implementing linked data and the barriers encountered; and some advice given by respondents to those considering implementing a linked data project or service. Differences with previous survey responses are noted, but as the majority of linked projects and services described are either not yet in production or implemented within the last two years, these differences may reflect new trends rather than changes in implementations.
