Importing, transforming, storing and indexing data should be easy.

Catmandu is a command line tool to access and convert data from your digital library, research services or any other open data sets. Catmandu provides a suite of Perl modules to ease the import, storage, retrieval, export and transformation of metadata records. Combine Catmandu modules with web application frameworks such as PSGI/Plack, document stores such as MongoDB and full text indexes such as Solr to create a rapid development environment for digital library services such as institutional repositories and search engines.

In the http://librecat.org/ project it is our goal to provide an open source set of programming components to build up digital libraries services suited to your local needs.

Blacklight is an open source Ruby on Rails gem that provides a discovery interface for any Solr index. Blacklight provides a default user interface which is customizable via the standard Rails (templating) mechanisms. Blacklight accommodates heterogeneous data, allowing different information displays for different types of objects and features faceted browsing, relevance based searching, bookmarkable items, permanent URLs for every item, and user tagging of items.
