Spotlight metadata for indexed items?

Using .dt3 files from metadata works really nice with e.g. Alfred to query and open DT items. It seems indexed items don’t get indexed in the Spotlight metadata. This makes sense (otherwise there would be duplicates). But as I think .dt3 are exceptionally useful (quick links directly inside DT3) - would there be a way to generate .dt3 metadata files for indexed content?

No, it’s a proprietary format.

Darn. Would there be another way to create .dt3 files for indexed content?
