IASA 2018 Annual Conference

The French National Audiovisual Institute was responsible since 1974 for the preservation of the audiovisual heritage produced by national broadcasts. The massive digitization of these collections in the 1990s, the digital capture of 162 channels since 2001, the opening of a "general public" website in 2006, are some of the steps taken by the Institute to take into account the digital technologies to benefit the audiovisual preservation. However, because of a historically "fragmented" IT architecture, the Institute has been suffering these last years from an under-utilization of its millions metadata collected in support of audiovisual collections, in particular in the frame of the legal deposit of radio and television. This is why since 2014 the Institute has been remodeling its documentary IT, in close coordination with the construction of a "data lake", which will allow merging the metadata from all enterprise tools (documentary, legal, commercial). The adoption of a linked data policy tends to develop new ways of using metadata, guaranteeing their quality, whether they come from external sources or from internal activities of documentary description. The presentation will describe this multiyear project, which aims to harmonize metadata as well as to promote new uses of these contents: online editorialisation, new offers to Ina’s clients for footage or complete programs, exploration and analysis of Ina’s collections by researchers and students, data mining. The construction of the data lake will help to develop more relevant and accurate offers to Ina’s partners in the respect of intellectual property and legal frame.
