Embark: Dynamic documents for making plans

The article argues that app-based trip planning is fragmented, because apps do not share context, their views cannot be combined, and their output is ephemeral, and that dynamic documents could fix this by combining the flexibility of text notes with live data, computations and views. It uses Paul's canoeing weekend as its example: he must copy locations from a reviews app into a weather app, cannot merge maps from the reviews, weather and routing apps, and can only save screenshots and URLs to record his reasoning. The authors say that transclusion, mentions, structured properties and inline formulas in existing tools each offer partial solutions, but most restrict what data and computations can be combined.
