Integrating the Kaltura Video Platform with the Photodentro Video Repository: A Case Study

This work presents a case study for the integration of two web-based systems, the "Kaltura" video platform and the "Photodentro Video" digital repository. The integration is based on the Open Archives Initiative Protocol for Metadata Harvesting and an associated automation, transformation, and push/pull notification strategy. Kaltura is a video management platform, which allows publishers and content producers to distribute, manage, and monetize their videos and other rich-media content. Photodentro Video is the Greek Educational Video Repository for primary and secondary education, based on the DSpace open source digital repository management system. The architecture and the orchestrated workflow of the integration of Kaltura and Photodentro Video are presented, with emphasis on the addressed challenges. Furthermore, the technologies for scaling up the video service provided by Kaltura to a massive number of end-users are reviewed and discussed along with the proposed solution. Finally, the performance of the overall integrated platform is evaluated.
