Note
Low Risk
Adds a new optional metadata field and wires it through PDF partitioning; behavior is additive and low risk aside from potential downstream consumers expecting a fixed metadata schema.
Overview
Adds table-provenance metadata for extracted tables.
ElementMetadatanow includes an optionaltable_extraction_method(e.g.,grid,tatr,vlm) and includes it in metadata consolidation.During PDF partitioning, the value is propagated from each
LayoutElementonto the resulting element metadata, enabling downstream consumers to identify which table-extraction algorithm produced a given table. Version is bumped to0.22.26and the changelog is updated accordingly.Reviewed by Cursor Bugbot for commit fe6135a. Bugbot is set up for automated code reviews on this repo. Configure here.
