    1. Summary from last time
    2. Discussion
      • Github for making profiles available
      • Platform identifiers
      • Support for collections
    3. Next steps



    Topic 1

    • Define platform identifiers (including version)
    • MUST have metadata-datacite.xml
    • Internal-Sender-Identifier not usable for identifying the sender
      • Sender-Identifier -> standardize
    • Missing points?
      • Fetch ok as long as URLs are permanent
      • Versioning might be missing

    Topic 2

    • Github for making profiles available
      • Good way, provides versioning
      • Some profiles (e.g. Fedora Commons) are already on GitHub
      • Is there an existing BagIt profile registry? (David asks Nick Ruest)
    • Platform identifiers
      • Compile list
      • Discussion at plenary if someone knows standard identifiers
      • Identify platform or instance?
        • Can be both, same identifier should stand for semantic and api-compatibility
      • Provide API + version?
        • There might be platforms w/o (public) API
        • Platform + version may allow to conclude on the API
      • Start with initial/basic map, wait for more comments
    • Support for Collections
      • What is a collection?
        • Option 1: Internal structure grouping datasets belonging together, e.g. investigation concept in Core Scientific Metadata Model (CSMD)
        • Option 2: ‘A collection is a digital object which is identified by a PID and consists of a set or a list of PIDs/Ids and a set of additional pointers/links and metadata together with each PID/Id.’ (Research Data Collections WG)
      • Dariah: stores single objects in bag, Fedora: arbitrary aggregations up to entire repository
      • Bags of bags? – “Funny” idea, but might be too complicated to work with
      • Currently, recommendations allow no way to describe sub-resources using metadata in META-INF
        • Suggest more flexible naming format of additional metadata, e.g. allow to include payload name in order to provide standard metadata a a payload element
      • Clean up comments in recommendations document (Thomas)
      • Publish talk(s) and minutes to WG file space after P10

    Topic 3
