There is a pressing need to provide concrete demonstrations of the benefits of linked data in order to help motivate the transition of library catalogs from MARC. Within LD4P2, work to enhance the discovery of library resources was the focus of WP4: Discovery. The partners had committed to working with the Blacklight framework to demonstrate enhanced discovery features such as:
- knowledge panel in search results to present contextual information powered by linked data;
- browsing based on authority files and links to related entities in external data;
- semantic search, which could include laying out alternative terms in a “no results” page, suggesting semantically related terms in a type-ahead, or providing richer, geo-based browse by leveraging URIs for places; and
- microdata on item pages to enable machine crawling.
In all of these areas there is opportunity for community input on and discussion of the best approaches and the desired outcomes. The LD4 Discovery Affinity Group will provide a forum for these discussions, with the following goals:
- identify exemplar systems/features the demonstrate the benefits of linked data and could be applied to library resources
- identify opportunities for enhanced discovery of library resources using linked data that can be implemented in the short to medium term
- document connections between cataloging practices and discovery outcomes
- document effective assessment approaches
- provide advice to LD4P2 partners and cohort members for WP4: Discovery
- Co-chaired by Jessie Keck & Huda Khan
