Libraries and Linked Data

• Increased flexibility for describing resources

• More reusable links from one record to another

• New options to contextualize external sources

• Ease of integration of catalogues into general purpose Web and social media

• Lightweight model easier to extend for future needs

• Facilitate re-use of data and ability for developers to incorporate into other apps

• Improved positioning of credible records from libraries within Web search engines
