The document discusses the German National Library's efforts to create and share library data as linked open data. It notes that currently library data formats are not readily understood outside of libraries. By linking authority data, national bibliographies, and ontologies, the library aims to make its data more accessible and useful to both libraries and other organizations. This linked data could help improve search capabilities and allow other services to more easily reuse library information. The ultimate goal is to contribute to a global linked data cloud and more interconnected web of bibliographic information.

most interesting dataset

libraries, we can create a critical mass of
data and head towards the bibliographical
future
