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
