Agenda & Notes

• Confirm details on removing Split and Merge
  • • Wrap up https://github.com/LD4/entity_metadata_management/pull/83.
    • "Examples in the library domain include splits and merges. The Deprecate Activity below illustrates how you can reflect these without explicitly typing them as splits and merge activities using a sequence of activities."
• Date properties
  • When to use the following in our context:
    • endTime property definition
      • Getty usage - used on each Activity, the value is the same as for the "created" property (see issues with "created" below)
      • LOC usage - not used presently.
    • startTime property definition
      • Getty usage - not used presently.
      • LOC usage - not used presently.
    • published property definition
      • Getty usage? - not used presently.
      • LOC usage - used for each Activity Object like "Add" or "Remove" or "Update."  I.e., not used for each Object of an Activity.   Represents when the Activity Object was 'published.'
    • updated property definition
      • Getty usage - not used presently.
      • LOC usage - used for each Object of an Activity.  Represents the (last) 'update' date of the Object which is the focus of the Activity.
    • deleted property definition
      • Getty usage - not used presently.
      • LOC usage  - not used presently.
    • 'created' - is used by Getty, but understood not to be an AS property; this will be dropped by JSON-LD tooling (ok, because redundant with endTime value)
  • Directions forward
    • From Slack... Given LC's and Getty's current date property usage on Activities, would LC be open to using endTime for the Activity? No. How important is it to say Activities were published at a certain date, versus saying the Activity was completed at an endTime? 
    • Or... do we allow for either?
    • Published is used with LC's implementation to talk about when the activity was made available in the stream, separate from the actual date of the activity, which is recorded on the object of the activity, see subjects for where changes differ from published. Names are changed and published on the same date.
    • Decided "Should include published on the the activity for when the activity was made available, and updated for when the object for when the change to the entity actually occurred."
