A timeline

Example document timeline.did

What it demonstrates

From 10.1 A timeline:

This definition was written with the timeline specification of DISL 17.2 (timeline.dis). It is a DID 0.1 definition, kept as written: it names the 0.1 schema and "did": "0.1", and it is read as a DID 0.2 definition with the same meaning. 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).
