DALIA: an Open Data repository for the open digital data of the Bologna CNR Research Area Library

The Bologna Research Area Library of the National Research Council is very active in many fields such as educational projects, services and support scientific research. NILDE (Network for Inter-Library Document Exchange), a software developed by the Bologna Library and adopted by a vast community of Italian and foreign libraries is one of the main projects carried out by the Library, started in 2001 and still active, More than 20 years of activity have brought the NILDE project to produce a large amount of digital data (multimedia materials from conferences, video interviews, multimedia teaching resources...) that need to be preserved and managed. Faced with the demand of consultation and reuse of these materials by the NILDE community, consisting of librarians, researchers and students for their daily work, the Bologna Research Area Library devised a simple way to organize the digital data produced by the projects in which it has been involved following the Open Science principles. The open data repository DALIA, accessible via web, was built to the purpose making use of the well proven open source tool CKAN. The archive has been populated starting from the data belonging to the NILDE project. The tests carried out with DALIA suggest its potentiality of a new service to be proposed to the Bologna Research Area researchers in order to introduce them to the procedures for archiving, describing and preserving data as suggested from EU.
