The Oslo Public Library, Deichmanske bibliotek, has developed a library services platform based on linked data. It can be seen in action at the library's website, and the source code is available on GitHub.
The platform uses a work-based model for its public-facing catalog; for an example of this "FRBR-ized" interface, see the display for the film Harry Potter and the Order of the Phoenix. The display provides prominently positioned work-level information, and then shows information for two different DVD versions of the movie, as well as a Blu-Ray version. It also very nicely highlights the film's position in the Harry Potter series, by providing "continues" and "continued in" links to the appropriate films. It also includes a "based on" link to the book of the same name. Following this link brings you to an even more impressive display of various print and audiobook holdings for this title.
More information about the behind-the-scenes cataloging work can be found in this post from 2014 on the library's blog.
