Metadata Extraction
MakerVault reads inside LightBurn .lbrn and .lbrn2 files at scan time to extract metadata that’s normally invisible without opening LightBurn.
What gets extracted
Section titled “What gets extracted”| Data | Source in file | Where it appears |
|---|---|---|
| Show Notes | <Notes> element | Detail panel, search index |
| Cut Settings | <CutSetting> elements | Detail panel, preview |
| Text Elements | <Shape Type="Text"> attributes | Detail panel, deep search |
| Font Names | Font attribute on text shapes | Detail panel, font auto-linking |
| App Version | <LightBurnProject AppVersion> | Detail panel |
| Embedded Thumbnail | <Thumbnail Source> | Preview |
File format handling
Section titled “File format handling”LightBurn uses two file formats:
.lbrn— Plain XML.lbrn2— Can be either plain XML or ZIP-compressed XML
MakerVault handles both transparently. It tries ZIP decompression first, then falls back to reading the file as plain XML.
When extraction happens
Section titled “When extraction happens”Metadata is extracted during the initial folder scan. If you add LightBurn files to a watched folder later, the file watcher picks them up and extracts metadata automatically.
MakerVault also has a stale metadata refresh that re-extracts data for files that were scanned before certain extraction features were added (like font extraction).
Storage
Section titled “Storage”Extracted metadata is stored in two forms:
- Structured JSON — For display in the detail panel and preview
- Flattened text — For full-text search via the FTS5 index
