<p>Importing, transforming, storing and indexing data should be easy.</p><p>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.</p><p>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.</p><p>Read an in depth introduction into Catmandu programming at https://github.com/LibreCat/Catmandu/wiki/Introduction.</p>
