http: //www. flickr. com/photos/danielito 311/5847295876/ You’ve heard of MOOCs… We’d like to introduce you to MOODs … Massive Open Online Discovery

Digital Collections Search (beta) : Blacklight discovery interface http: //webapp 1. dlib. indiana. edu/dcs/ IUCAT: Blacklight discovery interface http: //iucat. iu. edu IUB Library Web Site Search: Drupal + Solr Currently in development (wireframe)

One Big Index in the Sky (Solr) http: //www. flickr. com/photos/thukral/1983931186/

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

IUC AT : M MO ARC DS to IU Collections Data (MODS) S D O M : S DC Website Content

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

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 Z 39. 50 ? Fedora OAI-PMH ? Solr

Questions What data should we index? MARCXML IUCAT Z 39. 50 MODS Fedora OAI-PMH ? ? Solr

Our custom Solr schema

Questions How can we transform it? MARCXML IUCAT Z 39. 50 ? schema. x ml Solr MODS Fedora OAI-PMH ?

Questions How can we automate the process? MARCXML IUCAT Z 39. 50 XSLT Batch Ingest MODS Fedora OAI-PMH XSLT schema. x ml Solr
