A Pod of One's Own
The local device covers the ultra-private. The home NAS covers the family-scale. What's missing is everything that should be mine and reachable from anywhere, and shareable with specific people without handing it to a platform. That's the slot the Solid protocol is designed for.
The local device covers the ultra-private. The home NAS covers the family-scale private. What's missing from the ladder is everything that should be mine and reachable from anywhere, and everything I want to share with specific people without handing it to a platform.
That's the slot the Solid protocol is designed for. A pod is a personal online datastore you own, addressed by a WebID, with access control per resource. In Timeline OS terms, one pod supplies three rungs of the security ladder at once: a private space (tier 3, only me, authenticated, from anywhere), a shared space (tier 4, named people, revocable), and a public space (tier 5, the open web).
The fit is close. Timeline entries are small, timestamped, typed resources. Solid stores linked-data resources with per-resource access control. The unified index already treats "where does this live" as the load-bearing fact about every entry. A pod doesn't replace the archive. It's the reachable shelf of it. The public site still never reads it directly; it gets a hand-picked copy of the public space.
What had to survive contact with reality
Before betting the upper half of the ladder on Solid I ran a spike against the hard parts:
- Authentication from a browser app, without the session collapsing on every refresh.
- Reading an entry back as linked data, round-trip clean.
- Merging pod entries with local ones without loss.
- Working offline. The timeline must never depend on the pod being up.
- Is this pleasant enough to build a life on?
The verdict: go
The spike came back green, and a read-only first version now lives in the app. You authenticate to a pod, read your entries, and they join the same chronological stream as everything else. When the pod is unreachable, the app falls back to the rest of your timeline. For now the pod is the reachable, private shelf the ladder was missing. Writing entries back is the next rung.
