# observe\_rsc\_get\_raw/3 Source: https://zotonic.com/docs/2758/observe_rsc_get_raw-3 URI: https://zotonic.com/id/2758 Language: en Convert raw stored resource data to its current representation. Use this notification for resource migrations, including changes to property structures and serialization formats, such as converting legacy `props` values to JSON-friendly structures for `props_json`. Type: [foldr](/id/doc_developerguide_notifications#notification-foldr) Runs after decoding stored properties, before caching and `rsc_get`. It also runs when the database layer reads existing `rsc` properties to merge an update; that accumulator contains only custom properties, without database columns (`is_props_only = true`). Full raw resource reads set `is_props_only = false`. Observers must be idempotent and only convert stored data. Every returned value must be suitable for saving in the `rsc` record. Do not add computed fields, request-specific values, or perform database writes. Use `rsc_get` for computed fields. Reads themselves do not persist the conversion. `#rsc_get_raw{}` properties: - id: `m_rsc:resource_id()` - is\_props\_only: `boolean()`, defaults to `false`. `true` means only the merged `props`/`props_json` properties; `false` means the full raw resource record.
