10. Example

Contents of DID 0.1

This definition was written with the timeline specification of DISL 17.2 (timeline.dis). Several things to notice:

  • Elements are a flat list; relations are separate.
  • All placement of tasks and milestones lives in the model (start, end, assignee). The view stores only a moved label and the viewport.
  • References (assignee, relation ends) are plain ids.
  • Unset attributes and defaults are omitted (status of Build pages, lag of most dependencies).
