The Council on Library and Information Resources has released Linked Data for Libraries, Museums, and Archives: Survey and Workshop Report.
Here's an excerpt:
In June 2011, Stanford University hosted a group of librarians and technologists to examine issues and challenges surrounding the use of linked data for library applications. This report summarizes the activities and discussions that took place during the workshop, describes what came out of the workshop, outlines next steps identified by the participants, and provides contextual and background information, including preliminary reports and biographies of workshop participants. The workshop report was produced and edited by the participants and staff at Stanford University Libraries.
As background for workshop participants, CLIR commissioned Jerry Persons, technology analyst at Knowledge Motifs and Chief Information Architect emeritus at Stanford, to produce a survey of the linked-data landscape, and the projects and individuals associated with it. The survey focuses on the practical aspects of understanding and applying linked data practices and technologies to the metadata and content of libraries, museums, and archives. There are numerous links in the report and the survey that lead readers to many other sources and examples regarding the use of linked data methods.
