CERN Document Server (CDS) is the CERN Institutional Repository based on the Invenio open source digital repository framework. CDS aims to be the CERN's document hub. To achieve this we are transforming CDS into an aggregator over specialised repositories, each having its own software stack, with features enabled based on the repository's content. The first specialised repository created is CDS Videos. CDS Videos provides an integrated submission, long-term archival and dissemination of CERN video material. It offers a complete solution for the CERN video team, as well as for any department or user at CERN, to upload video productions. Since it was released in production, the yearly number of uploaded videos at CERN doubled, showing that the creation of a specialised platform based on user needs, rather that a generic platform capable of dealing with many document types, has been benefit for the CERN community and for the video heritage of CERN.
