what about exposing dead props into rest API
let user to store preferences, labels on resources
| Use case | What it looks like | Why dead-props help |
|---|---|---|
| Photo annotations | captions, ratings (1-5), notes per photo | already keyed by `file_id`; round-trips via WebDAV without re-implementing |
| Web-UI tags / labels | `oxi:user:tag/project=alpha`, color flags, "archived" markers | per-resource user metadata without new tables |
| Folder UI preferences | default sort, default view mode, "favourite" flag | persistent per-folder, shared across users on shared drives |
| Cross-protocol bridge | Thunderbird sets `oxi:lastsync=...` via PROPPATCH → web UI reads it via REST | one store, two surfaces — visibility goes both ways |
| Workflow / approval state | `reviewed_by=alice`, `due=2026-09-15` | ad-hoc state per resource without schema sprawl |
| Third-party integrations | external apps store scratch space per resource | lower barrier than implementing WebDAV |
