  1. Content Terminology in CDNIdraft-deventer-cdni-content-terminology IETF 81 – Quebec, CDNI WG Oskar van Deventer Ray van Brandenburg

  2. Current definition of ‘Content’ As defined in draft-jenkins-cdni-problem-statement-02: “Content: Any form of digital data. One important form of Content with additional constraints on Distribution and Delivery is continuous media (i.e. where there is a timing relationship between source and sink). “ • Generic definition may seem desirable but might prove problematic in the area of Content Distributon Metadata

  3. How to deal with …? • Content that is available in different formats/codecs • Single content ‘object’ (with metadata) ? • Or separate content ‘objects’ (each with their own metadata)? • Content that is available in different qualities • Single content ‘object’ (with metadata) ? • Or separate content ‘objects’ (each with their own metadata)? • Segmented content (e.g. http adaptive streaming) • Every segment as a content ‘object’? • Or single content ‘object’ for all segments • Are segments always moved as if they are a single entity? Different CDNs might deal with this in different ways!

  4. Need for additional content terminology • Terminology for describing content ‘groups’ • Terminology for describing relationships between content objects Thanks!
