You’ve heard of MOOCs… We’d like to introduce you to MOODs … Massive Open Online Discovery
IUCAT: Blacklight discovery interface Digital Collections Search (beta) : Blacklight discovery interface IUB Library Web Site Search: Drupal + Solr Currently in development (wireframe)
One Big Index in the Sky (Solr)
Phase One Enable indexing & combined search of Indiana University catalog, repository, digital collections, website data – Combine feeds of catalog (IUCAT) & digital collections (DCS) data via MODS – Single index: author, date, format, language, location, & subject – Facets: author, date, format, & subject
Website Content IU Collections Data (MODS) IUCAT: MARC to MODS DCS: MODS
Phase Two Expose IU dataset for potential combination with other institutional datasets IU Dataset Pat Q Scholar I.M. Hacker
Goal: Identify best practices for UX around discovery in the context of metadata Surveyed institutions to identify approaches to Solr indexing and end-user options

Solr Schemas Used
Solr Schema Fields Modified
Reasons for Modifying Fields Connections to original metadata
What is being indexed?
Metadata mapped to Solr/SolrMARC
Discovery Layer
Shared File Sets Just what we asked for!
Proof of Concept Internship Goal: Explore possibilities of combining multiple metadata feeds into one central index Feed 1 Feed 2 Index ?
Questions What are our data sources? ? ? Index ?
Questions What is Apache Solr, and how does it work? IUCAT Fedora Solr ? ? ? ? ? ? ? Librarian-friendly documentation is on the way!
Questions What’s the best way to get the data? IUCAT Fedora Solr ? ? ?
Questions What’s the “native” format? IUCAT Fedora Solr ? Z39.50 OAI-PMH ? ?
Questions What data should we index? IUCAT Fedora Solr ? Z39.50 OAI-PMH MARCXML MODS ?
Our custom Solr schema
Questions How can we transform it? IUCAT Fedora Solr Z39.50 OAI-PMH MARCXML MODS schema.x ml ? ?
Questions How can we automate the process? IUCAT Fedora Solr Z39.50 OAI-PMH MARCXML MODS schema.x ml XSLT Batch Ingest
Future Goals ? Fedora Solr ? OAI-PMH ? MODS schema.xml XSLT Batch Ingest IUCAT Z39.50 MARCXML XSLT ? ? ?
